[0008] A: Embodiment FIG. 1 is a block diagram illustrating a configuration of an acoustic system 100 according to one embodiment of the present disclosure. The acoustic system 100 of this embodiment includes an acoustic processing device 10 and an information processing device 20. The acoustic processing device 10 is a digital mixer that executes various acoustic processes. The information processing device 20 is a computer system that assists the operation of the acoustic processing device 10. For example, a smartphone, a tablet terminal, a personal computer, or the like is used as the information processing device 20. The acoustic processing device 10 and the information processing device 20 are capable of communicating with each other. Note that the functions of the information processing device 20 may be incorporated in the acoustic processing device 10.

[0009] The sound processing device 10 is a computer system including a control device 11, a storage device 12, a communication device 13, an operation device 14, a signal processing device 15, and an input / output interface 16.

[0010] The control device 11 is a single or multiple processors that control each element of the sound processing device 10. Specifically, the control device 11 is configured by one or more types of processors, such as a central processing unit (CPU), a graphics processing unit (GPU), a sound processing unit (SPU), a digital signal processor (DSP), a field programmable gate array (FPGA), or an application specific integrated circuit (ASIC).

[0011] The storage device 12 is one or more memories that store programs executed by the control device 11 and various data used by the control device 11. For example, a known recording medium such as a semiconductor recording medium or a magnetic recording medium, or a combination of multiple types of recording media, is used as the storage device 12. Note that, for example, a portable recording medium that is detachably attached to the sound processing device 10, or a recording medium that the control device 11 can access via the communication network 200 (for example, cloud storage) may be used as the storage device 12.

[0012] The communication device 13 communicates with the information processing device 20. The communication between the communication device 13 and the information processing device 20 may be either wired communication or wireless communication. Note that the communication device 13 separate from the sound processing device 10 may be connected to the sound processing device 10.

[0013] 2 is a plan view illustrating an example of the appearance of the sound processing device 10. The sound processing device 10 includes a housing 50. The housing 50 is a hollow structure that houses each element of the sound processing device 10. Specifically, the control device 11, the storage device 12, the communication device 13, the signal processing device 15, and the input / output interface 16 are housed and supported in the housing 50.

[0014] The operation device 14 is an input device that accepts operations by a user U1 of the sound processing device 10. As illustrated in Fig. 2, the operation device 14 includes three operation knobs 51-1 to 51-3, three operation buttons 52a to 52c, a fader 53, and an operation knob 54. The three operation knobs 51-1 to 51-3, the three operation buttons 52a to 52c, the fader 53, and the operation knob 54 are physical operators provided on the housing 50. The operation knob 51-1 is an example of a "first operator", and the operation knob 51-2 is an example of a "second operator".

[0015] Each operation knob 51-n (n=1 to 3) is a rotating body that can be rotated within a predetermined range by operation of the user U1. The operation knob 54 is also a rotating body that can be rotated in a similar manner. The three operation buttons 52a to 52c are operators that can be pressed by the user U1. The fader 53 is an operator that can be moved linearly by the user U1. The operation device 14 may include, for example, a touch panel that detects contact by the user U1.

[0016] The input / output interface 16 in Fig. 1 is an interface for connecting peripheral devices to the sound processing device 10. Specifically, the input / output interface 16 is composed of a plurality of connection terminals corresponding to different formats. Each connection terminal is installed, for example, on the side surface of the housing 50. For example, the input / output interface 16 includes connection terminals for wired connection, such as a Universal Serial Bus (USB) terminal, a High-Definition Multimedia Interface (HDMI / registered trademark) terminal, a Musical Instrument Digital Interface (MIDI) terminal, or a phone terminal. Note that the peripheral devices may be connected to the sound processing device 10 wirelessly.

[0017] In this embodiment, it is assumed that the sound collection device 31, the sound emission device 32, and the game device 33 are connected to the sound processing device 10 as peripheral devices. The sound collection device 31 is a microphone that generates a sound signal A-1 by collecting the sound uttered by the user U1. The sound emission device 32 emits a reproduced sound corresponding to the sound signal Bx output from the sound processing device 10. For example, a speaker or a headphone is used as the sound emission device 32. Note that an A / D converter that converts the sound signal A-1 from analog to digital and a D / A converter that converts the sound signal Bx from digital to analog are omitted from the illustration for convenience. The game device 33 is an information device that provides a game to the user U1. The game device 33 supplies the sound processing device 10 with a sound signal A-3 that represents a sound corresponding to the progress of the game. Note that the game device 33 is not limited to an information device dedicated to a game, and may be a general-purpose information device such as a smartphone, a tablet terminal, or a personal computer.

[0018] The signal processing device 15 performs acoustic processing on the sound signals An (A-1 to A-3). The acoustic processing is, for example, signal processing such as mixing, filtering, or equalizing. The signal processing device 15 is realized by, for example, a DSP dedicated to acoustic processing. Note that some or all of the functions of the signal processing device 15 may be realized by the control device 11 executing a program stored in the storage device 12.

[0019] The information processing device 20 is a computer system including a control device 21, a storage device 22, a communication device 23, an operation device 24, and a display device 25. The information processing device 20 may be realized as a single device, or may be realized as a plurality of devices configured separately from each other.

[0020] The control device 21 is a single or multiple processors that control each element of the information processing device 20. Specifically, the control device 21 is configured by one or more types of processors such as a CPU, a GPU, an SPU, a DSP, an FPGA, or an ASIC.

[0021] The storage device 22 is one or more memories that store programs executed by the control device 21 and various data used by the control device 21. For example, a known recording medium such as a semiconductor recording medium or a magnetic recording medium, or a combination of multiple types of recording media, is used as the storage device 22. Note that, for example, a portable recording medium that is detachably attached to the information processing device 20, or a recording medium that the control device 21 can access via the communication network 200 (for example, cloud storage) may be used as the storage device 22.

[0022] The communication device 23 communicates with the sound processing device 10. Note that a communication device 13 separate from the sound processing device 10 may be connected to the sound processing device 10. The communication device 23 also communicates with the distribution device 41 and the terminal device 42 via a communication network 200 such as the Internet. For example, the communication device 23 includes a communication unit that communicates with the sound processing device 10 and a communication unit that communicates with the distribution device 41 and the terminal device 42.

[0023] The distribution device 41 is a server system that distributes video content including the sound signal By generated by the sound processing device 10. The terminal device 42 is an information device used by the user U2. For example, an information device such as a smartphone, a tablet terminal, or a personal computer is exemplified as the terminal device 42. The user U2 is, for example, a participant in the recording of the video content. That is, the user U1 plays a game while talking with the user U2. The terminal device 42 transmits a sound signal A-2 representing a voice pronounced by the user U2 to the information processing device 20. The communication device 23 of the information processing device 20 receives the sound signal A-2 transmitted from the terminal device 42. The distribution device 41 and the terminal device 42 are examples of "information devices".

[0024] The operation device 24 is an input device that accepts operations by the user U1. For example, input devices such as a keyboard or a mouse are exemplified as the operation device 24. The display device 25 displays an image under the control of the control device 21. For example, various display panels such as a liquid crystal display panel or an organic EL (Electroluminescence) panel are used as the display device 25. Note that a touch panel mounted on the display device 25 may be used as the operation device 24. In addition, the operation device 24 or the display device 25, which are separate from the information processing device 20, may be connected to the information processing device 20 by wire or wirelessly.

[0025] 3 is a block diagram illustrating an example of a functional configuration of the sound processing device 10. An sound processing unit 60 and an operation control unit 70 are realized by execution of a program by the control device 11 and an electronic circuit mounted on the signal processing device 15. The sound processing unit 60 and the operation control unit 70 are housed in a housing 50.

[0026] The sound processing unit 60 generates a sound signal Bx and a sound signal By by performing sound processing on the three systems of sound signals A-1 to A-3. As described above, the sound signal A-1 is a signal representing the voice of the user U1, the sound signal A-2 is a signal representing the voice of the user U2, and the sound signal A-3 is a signal representing the sound of the game. For example, the sound signal A-1 is an example of a "first sound signal," the sound signal A-2 is an example of a "second sound signal," and the sound signal A-3 is an example of a "third sound signal."

[0027] Sound processing section 60 is equipped with three input channels 61-1 to 61-3, three adjustment sections 62-1 to 62-3, three adjustment sections 63-1 to 63-3, a first mixing bus 64, a second mixing bus 65, and an output adjustment section 66.

[0028] Each input channel 61-n performs acoustic processing on the sound signal An. FIG. 4 is a block diagram of the input channel 61-1 of the sound processing unit 60. The input channel 61-1 includes a first amplifier 611, an effect imparting unit 612, and a second amplifier 613. The first amplifier 611 amplifies the sound signal A-1 in response to an operation of the user U1 on the operation knob 54. The effect imparting unit 612 imparts various acoustic effects to the sound signal A-1 in response to an operation of the user U1 on the three operation buttons 52a to 52c. For example, the effect imparting unit 612 performs various effect imparting processes such as an equalizing process for adjusting the frequency characteristics of the sound signal A-1, a reverberation imparting process for imparting reverberation to the sound signal A-1, and a voice quality conversion process for converting the voice quality of the sound signal A-1. The second amplifier 613 adjusts the volume of the sound signal A-1 in response to an operation of the user U1 on the fader 53. The second amplifier 613 may adjust the volume of the sound signal A-1 in response to an operation on the operation knob 51-1. The second amplifier 613 may be disposed after the adjustment unit 62-1.

[0029] The input channel 61-2 executes sound processing such as effect imparting processing on the sound signal A-2. For example, the input channel 61-2 executes sound image localization processing for localizing the sound image of the voice of the user U2 represented by the sound signal A-2. The parameters of the sound processing by the input channel 61-2 are adjusted in response to, for example, the operations on the operation knobs 51-1 to 51-3.

[0030] Similarly, the input channel 61-3 executes sound processing such as effect imparting processing on the sound signal A-3. For example, the input channel 61-3 executes virtual surround processing that assigns game sounds represented by the sound signal A-3 to multiple virtual sound sources. The parameters of the sound processing by the input channel 61-3 are adjusted according to the operation of the operation knobs 51-1 to 51-3, for example. Note that the types of sound processing executed by each input channel 61-n are not limited to the above examples and can be changed arbitrarily.

[0031] Each adjustment unit 62-n adjusts the sound signal An supplied from the input channel 61-n. The sound signal An after adjustment by each adjustment unit 62-n is supplied to the first mixed bus 64. The adjustment unit 62-n of this embodiment adjusts the sound signal An according to a send level Xn. The send level Xn is a parameter (gain) that specifies the signal level of the sound signal An supplied from the input channel 61-n to the first mixed bus 64. In other words, the adjustment unit 62-n adjusts the volume of the sound signal An according to the send level Xn. Each send level Xn is stored in the storage device 12 and is set according to an operation by the user U1.

[0032] The adjustment unit 62-1 is an example of a “first adjustment unit,” the adjustment unit 62-2 is an example of a “third adjustment unit,” and the adjustment unit 62-3 is an example of a “fifth adjustment unit.” The feed amount X-1 is an example of a “first parameter,” the feed amount X-2 is an example of a “third parameter,” and the feed amount X-3 is an example of a “fifth parameter.”

[0033] The first mixing (MIX) bus generates a sound signal Bx by mixing a sound signal A-1 adjusted by the adjustment unit 62-1, a sound signal A-2 adjusted by the adjustment unit 62-2, and a sound signal A-3 adjusted by the adjustment unit 62-3. That is, the sound signals A-1 to A-3 of the three systems are added together at a mixing ratio according to each feed amount Xn to generate the sound signal Bx. The first mixing bus 64 is an example of a "first mixing unit."

[0034] The output adjustment unit 66 adjusts the signal level of the sound signal Bx generated by the first mixed bus 64. The sound signal Bx output from the output adjustment unit 66 is supplied to the sound emitting device 32. The sound of the sound signal Bx reproduced by the sound emitting device 32 is heard by the user U1 of the sound processing device 10. Specifically, the user U1 can hear a mixed sound of his / her own voice (sound signal A-1), the voice of the user U2 (sound signal A-2), and the game sound (sound signal A-3). The sound signal Bx is an example of a "first output signal."

[0035] Each adjustment unit 63-n adjusts the sound signal An supplied from the input channel 61-n. The sound signal An after adjustment by each adjustment unit 63-n is supplied to the second mixed bus 65. The adjustment unit 63-n of this embodiment adjusts the sound signal An according to the feed amount Yn. The feed amount Yn is a parameter (gain) that specifies the signal level of the sound signal An supplied from the input channel 61-n to the second mixed bus 65. In other words, the adjustment unit 63-n adjusts the volume of the sound signal An according to the feed amount Yn. Each feed amount Yn is stored in the storage device 12 and is set according to an operation by the user U1.

[0036] The adjustment unit 63-1 is an example of a “second adjustment unit,” the adjustment unit 63-2 is an example of a “fourth adjustment unit,” and the adjustment unit 63-3 is an example of a “sixth adjustment unit.” The feed amount Y-1 is an example of a “second parameter,” the feed amount Y-2 is an example of a “fourth parameter,” and the feed amount Y-3 is an example of a “sixth parameter.”

[0037] The second mixing (MIX) bus generates a sound signal By by mixing the sound signal A-1 adjusted by the adjustment unit 63-1, the sound signal A-2 adjusted by the adjustment unit 63-2, and the sound signal A-3 adjusted by the adjustment unit 63-3. That is, the sound signal By is generated by adding the three sound signals A-1 to A-3 at a mixing ratio according to each feed amount Yn. As described above, in this embodiment, two sound signals (Bx, By) can be generated by mixing the sound signal A-1, the sound signal A-2, and the sound signal A-3 at different mixing ratios. The second mixing bus 65 is an example of a "second mixing unit".

[0038] The sound signal By output from the second mixed bus 65 is supplied to the information processing device 20. The information processing device 20 generates video content including, for example, a video including a game screen and an image of the user U1, and the sound signal By supplied from the sound processing device 10, and transmits the video content to the distribution device 41. That is, the sound signal By is transmitted to the distribution device 41 via the communication network 200. A viewer of the video content (including the user U2) can hear a mixed sound of the voice of the user U1 (sound signal A-1), the voice of the user U2 (sound signal A-2), and the sound of the game (sound signal A-3) by viewing the video content distributed from the distribution device 41. The sound signal By is an example of a "second output signal." The sound signal By may be transmitted to the terminal device 42 of each viewer without passing through the distribution device 41.

[0039] As can be understood from the above description, each of the forwarding amounts Xn is a parameter related to the sound for playback (monitoring) for the user U1, and each of the forwarding amounts Yn is a parameter related to the sound for distribution of the video content. As described above, according to this embodiment, it is possible to generate a sound signal Bx for listening by the user U1 and a sound signal By for distribution.

[0040] The operation control unit 70 in Fig. 3 controls the operation of the sound processing unit 60. The operation control unit 70 sets each of the feed amounts Xn (X-1 to X-3) and each of the feed amounts Yn (Y-1 to Y-3) stored in the storage device 12 in response to an instruction from the user U1. In this embodiment, the operation modes for setting the feed amounts Xn and Yn include an individual control mode and an interlocking control mode. The individual control mode is an example of a "first operation mode", and the interlocking control mode is an example of a "second operation mode".

[0041] 5 is a conceptual diagram for explaining the operation modes. The individual control mode is an operation mode in which the feed amount Xn and the feed amount Yn are individually controlled. That is, the feed amount Xn and the feed amount Yn are individually controlled by different operations by the user U1. Specifically, in the individual control mode, the operation control unit 70 sets the feed amount Xn in response to an operation Qx-n by the user U1 on the operation knob 51-n of the sound processing device 10, and sets the feed amount Yn in response to an operation Qy-n by the user U1 on the operation device 24 of the information processing device 20. As explained above, the operation Qx-n and the operation Qy-n are different operations.

[0042] On the other hand, the interlocking control mode is an operation mode in which the feed amount Xn and the feed amount Yn are controlled in an interlocking manner. Specifically, in the interlocking control mode, the operation control unit 70 sets both the feed amount Xn and the feed amount Yn in response to an operation Qx-n by the user U1 on the operation knob 51-n of the sound processing device 10. Specifically, in the interlocking operation mode, the feed amount Xn and the feed amount Yn are set to equal values ​​in response to the operation on the operation knob 51-n.

[0043] As shown in the above example, the operation knob 51-n is used for operating the feed amount Xn alone in the individual control mode and for operating the feed amount Xn and the feed amount Yn together in the interlocking control mode. However, the operation knob 51-n cannot be used for operating the feed amount Yn alone. For example, the process of assigning the feed amount Yn alone to the operation knob 51-n or the process of controlling only the feed amount Yn in response to the operation of the operation knob 51-n is not executed in this embodiment.

[0044] Note that operation Qx-1 is an example of a "first operation," and operation Qy-1 is an example of a "second operation." Operation Qx-2 is an example of a "third operation," and operation Qy-2 is an example of a "fourth operation." Operation Qx-3 is an example of a "fifth operation," and operation Qy-3 is an example of a "sixth operation."

[0045] 6 is a schematic diagram of a screen (hereinafter referred to as "setting screen 80") displayed on display device 25 for setting each feed amount Yn. Setting screen 80 includes three regions R-1 to R-3 corresponding to different feed amounts Yn.

[0046] In each region Rn, a selection button 81-n, an adjustment bar 82-n, and a signal level image 83-n are arranged. The selection button 81-n and the adjustment bar 82-n in each region Rn are virtual controls displayed on the display device 25. The selection button 81-n is an example of a "selection control." The signal level image 83-n is an image that represents the signal level of the sound signal An after adjustment by each adjustment unit 63-n.

[0047] The selection button 81-n is a virtual operator for the user U1 to select either the interlocking control mode or the individual control mode. Specifically, every time the user U1 operates the selection button 81-n, the operation mode is changed from one of the interlocking control mode and the individual control mode to the other. The control device 21 notifies the sound processing device 10 of the change in the operation mode via the communication device 23.

[0048] As can be seen from Fig. 6, the selection buttons 81-n are arranged for each area Rn. The user U1 can individually operate the selection buttons 81-n for each of the three areas R-1 to R-3. That is, an operation mode is set individually for each sound signal An. For example, an operation mode for a pair of feed amounts X-1 and Y-1 is set in response to an operation on the selection button 81-1, an operation mode for a pair of feed amounts X-2 and Y-2 is set in response to an operation on the selection button 81-2, and an operation mode for a pair of feed amounts X-3 and Y-3 is set in response to an operation on the selection button 81-3.

[0049] The adjustment bar 82-n of each region Rn is a virtual operator that allows the user U1 to adjust the feed amount Yn in the individual control mode. The user U1 can set the feed amount Yn to a desired value by operating the adjustment bar 82-n using the operation device 24. An operation Qy-n in Fig. 5 is an operation by the user U1 on the adjustment bar 82-n of the region Rn. The control device 21 notifies the sound processing device 10 of the setting value of the feed amount Yn instructed by the user U1 via the communication device 23.

[0050] 7 is a flowchart of a process (hereinafter referred to as a "first process") executed by the control device 21 of the information processing device 20 in relation to switching of the operation mode. The first process is executed sequentially or in parallel for each sound signal An, and is repeated at a predetermined cycle.

[0051] When the first process is started, the control device 21 judges whether or not a transition from the individual control mode to the coordinated control mode has been instructed by the user U1 operating the selection button 81-n (Sa1).

[0052] When a transition to the linked control mode is instructed (Sa1: YES), the control device 21 sets the adjustment bar 82-n to an invalid state (Sa2). The invalid state is a state in which an operation Qy-n from the user U1 on the adjustment bar 82-n is not accepted. The adjustment bar 82-n in the invalid state is displayed, for example, as a grayed-out state. Furthermore, the control device 21 notifies the sound processing device 10 of the transition from the individual control mode to the linked control mode via the communication device 23 (Sa3). On the other hand, when a transition to the linked control mode is not instructed (Sa1: NO), the state control of the adjustment bar 82-n (Sa2) and the notification of the operation mode transition (Sa3) are not executed.

[0053] Furthermore, the control device 21 judges whether or not a transition from the interlocking control mode to the individual control mode has been instructed by the user U1 operating the selection button 81-n (Sa4).

[0054] When a transition to the individual control mode is instructed (Sa4: YES), the control device 21 sets the adjustment bar 82-n to an enabled state (Sa5). The enabled state is a state in which an operation Qy-n from the user U1 to the adjustment bar 82-n is accepted. The control device 21 also notifies the sound processing device 10 of the transition from the linked control mode to the individual control mode via the communication device 23 (Sa6). On the other hand, when a transition to the individual control mode is not instructed (Sa4: NO), the state control of the adjustment bar 82-n (Sa5) and the notification of the operation mode transition (Sa6) are not executed.

[0055] In the individual control mode, the user U1 can instruct to change the forward amount Yn in response to an operation Qy-n on the adjustment bar 82-n in an active state. The control device 21 judges whether or not the operation Qy-n has been performed by the user U1 (Sa7). If the operation Qy-n from the user U1 has occurred (Sa7: YES), the control device 21 updates the display of the adjustment bar 82-n in response to the operation Qy-n (Sa8). The control device 21 also notifies the sound processing device 10 of the operation Qy-n performed by the user U1 (Sa9). Specifically, the control device 21 transmits the value of the forward amount Yn after the change in response to the operation Qy-n from the communication device 23 to the sound processing device 10. The above is a specific procedure of the first process.

[0056] 8 is a flowchart of a process (hereinafter referred to as "second process") executed by the control device 11 (operation control unit 70) of the sound processing device 10 in relation to switching of the operation mode. The second process is executed sequentially or in parallel for each sound signal An, and is repeated at a predetermined cycle.

[0057] When the second process is started, the control device 11 judges whether or not a transition from the interlocking control mode to the individual control mode has been notified from the information processing device 20 (Sb1). In other words, it is judged whether or not a transition from the interlocking control mode to the individual control mode has been instructed by the user U1.

[0058] When the mode has transitioned to the individual control mode (Sb1: YES), the control device 11 releases the link between the feed amount Xn and the feed amount Yn (Sb2). The values ​​of the feed amount Xn and the feed amount Yn stored in the storage device 12 are maintained at the values ​​immediately before the transition to the individual control mode. On the other hand, when the mode has not transitioned to the individual control mode (Sb1: NO), the link between the feed amount Xn and the feed amount Yn is not released.

[0059] The control device 11 determines whether or not a transition from the individual control mode to the coordinated control mode has been notified by the information processing device 20 (Sb3). That is, it is determined whether or not a transition from the individual control mode to the coordinated control mode has been instructed by the user U1.

[0060] If the mode has transitioned to the interlocking control mode (Sb3: YES), the control device 11 sets the current feed amount Yn to the value of the feed amount Xn immediately before the transition (Sb4). That is, the feed amount Yn is changed to a value equal to the feed amount Xn. On the other hand, if the mode has not transitioned to the interlocking control mode (Sb3: NO), the control of the feed amount Yn (Sb4) is not executed. The above is the specific procedure of the second process.

[0061] 9 is a flowchart of a process (hereinafter referred to as a "setting process") executed by the control device 11 (operation control unit 70) for setting the feed amount Xn and the feed amount Yn. The setting process is executed sequentially or in parallel for each sound signal An, and is repeated at a predetermined cycle.

[0062] When the setting process is started, the control device 11 judges whether or not the current operation mode is the individual control mode (Sc1). If the current operation mode is the individual control mode (Sc1: YES), the control device 11 judges whether or not an operation Qx-n on the operation knob 51-n has been accepted (Sc2). If the operation Qx-n has been accepted (Sc2: YES), the control device 11 controls the feed amount Xn in accordance with the operation Qx-n (Sc3). Specifically, the value of the feed amount Xn stored in the storage device 12 is changed in accordance with the operation Qx-n. On the other hand, if the operation Qx-n has not been accepted (Sc2: NO), the control device 11 does not execute the control of the feed amount Xn (Sc3).

[0063] In the individual control mode, the control device 11 judges whether or not an operation Qy-n by the user U1 has been notified from the information processing device 20 (Sc4). That is, it is judged whether or not an operation Qy-n has been performed by the user U1.

[0064] When the operation Qy-n is notified (Sc4: YES), the control device 11 controls the feed amount Yn in accordance with the operation Qy-n (Sc5). Specifically, the value of the feed amount Yn stored in the storage device 12 is changed to the value notified from the information processing device 20. On the other hand, when the operation Qy-n is not notified (Sc4: NO), the control device 11 does not execute the control of the feed amount Yn (Sc5). As described above, in the individual control mode, the control of the feed amount Xn in accordance with the operation Qx-n (Sc3) and the control of the feed amount Yn in accordance with the operation Qy-n (Sc5) are executed separately.

[0065] On the other hand, if the current operation mode is the interlocking control mode (Sc1: NO), the control device 11 judges whether or not an operation Qx-n on the operation knob 51-n has been accepted (Sc6). If the operation Qx-n has been accepted (Sc6: YES), the control device 11 controls the feed amount Xn and the feed amount Yn in an interlocking manner according to the operation Qx-n (Sc7). Specifically, the feed amount Xn and the feed amount Yn are changed to equal values. On the other hand, if the operation Qx-n has not been accepted (Sc6: NO), the control device 11 does not execute the control of the feed amount Xn and the feed amount Yn (Sc7).

[0066] As described above, in this embodiment, in the individual control mode, the feed amount Xn and the feed amount Yn are each individually controlled. Therefore, each of the feed amount Xn and the feed amount Yn can be precisely adjusted according to the intention of the user U1. On the other hand, in the interlocking control mode, the feed amount Xn and the feed amount Yn are controlled according to the operation Qx-n on the operation knob 51-n. That is, the operation Qx-n is used in common for the control of the feed amount Xn and the control of the feed amount Yn. Therefore, in the interlocking control mode, the operation Qy-n for adjusting the feed amount Yn is not required. According to the above embodiment, the operation required for controlling the feed amount Xn and the feed amount Yn can be simplified compared to the embodiment in which only the individual control of the feed amount Xn and the feed amount Yn is allowed. That is, the adjustment work of the mixture ratio in the first mixed bus 64 and the second mixed bus 65 is easy. In particular, in this embodiment, the feed amount Xn and the feed amount Yn are controlled in an interlocking manner. Therefore, both the feed amount Xn and the feed amount Yn can be easily changed according to the intention of the user U1.

[0067] In this embodiment, the feed amount Yn immediately before the transition from the interlocking control mode to the individual control mode is maintained even immediately after the transition to the individual control mode. Therefore, the feed amount Xn and the feed amount Yn are individually controlled after the transition to the individual control mode, based on the feed amount Xn and the feed amount Yn set in an interlocking manner in the interlocking control mode. That is, in the interlocking control mode, the feed amount Yn is set to a target value in a state in which the feed amount Xn and the feed amount Yn are interlocked, and then in the individual control mode, the feed amount Xn is fine-tuned by the difference between the target value of the feed amount Yn and the target value of the feed amount Xn, so that each of the feed amounts Xn and Yn can be quickly and easily set to the target value.

[0068] In the adjustment process exemplified above, the user U1 can check both the adjustment status of the feed amount Yn (and the feed amount Xn) in the interlocking control mode and the adjustment status of the feed amount Xn in the individual control mode at any time by listening to the sound reproduced by the sound emitting device 32. That is, by listening to the sound reproduced by the sound emitting device 32, the user U1 can complete the adjustment of both the feed amount Xn and the feed amount Yn.

[0069] In addition, in this embodiment, when the control mode is switched from the individual control mode to the interlocking control mode, the feed amount Yn is set to the value of the feed amount Xn immediately before the transition. That is, the feed amount Yn can be adjusted in the interlocking control mode with the feed amount Xn set in the individual control mode as the initial value. Therefore, compared with a form in which the feed amount Yn is not changed when the control mode is switched to the interlocking control mode, the operation for setting both the feed amount Xn and the feed amount Yn to the target value can be simplified.

[0070] In this embodiment, an operation mode (individual control mode / interlocking control mode) is set individually for each pair of feed amount Xn and feed amount Yn. Therefore, compared with a form in which the operation mode is set collectively for the three systems of sound signals A-1 to A-3, each feed amount Xn and each feed amount Yn can be set in a variety of ways by a simple operation.

[0071] In the interlocking control mode, the feed amount Xn and the feed amount Yn are controlled according to the operation Qx-n on the operation knob 51-n, so that the sound processing device 10 does not need a physical operator dedicated to adjusting the feed amount Yn (operation Qy-n). Therefore, compared to a form in which a physical operator for the operation Qy-n is provided in addition to the operation knob 51-n for the operation Qx-n in the sound processing device 10, it is easy to reduce the size of the housing 50 of the sound processing device 10. Moreover, the selection button 81 for selecting the operation mode is a virtual operator displayed on the display device 25. Therefore, compared to a form in which a physical operator for selecting the operation mode is provided in the housing 50, it is easy to reduce the size of the housing 50 of the sound processing device 10.

[0072] B: Variation Specific modified embodiments added to each of the above-mentioned embodiments are exemplified below. Two or more embodiments selected from the following examples may be appropriately combined as long as they are not mutually contradictory.

[0073] (1) In the above embodiment, the feed amount Xn and the feed amount Yn are set to equal values ​​in the interlocking control mode, but the configuration in which the feed amount Xn and the feed amount Yn are set to equal values ​​in the interlocking control mode is not essential to the present disclosure. That is, the "interlocking" relationship between the feed amount Xn and the feed amount Yn is not limited to the example in the above embodiment. For example, the concept of "interlocking" also includes a relationship in which the feed amount Xn and the feed amount Yn are interlocked while maintaining a predetermined difference. The "interlocking" in the above embodiment is a relationship in which the feed amount Xn and the feed amount Yn are controlled to correspond to a change in the other one.

[0074] Furthermore, even if the manner of change of the feed amount Xn and the manner of change of the feed amount Yn are different, they can be included in the concept of "linkage." The manner of change is, for example, a change condition such as the direction of change (increase / decrease / maintenance), the rate of change, or the amount of change. As can be understood from the above explanation, the "linkage" between the feed amount Xn and the feed amount Yn is comprehensively expressed as a relationship in which the feed amount Xn and the feed amount Yn change in response to a common operation Qx-n.

[0075] (2) In the above embodiment, the control of the send amount (Xn, Yn) for the sound signal An is exemplified, but the parameters controlled for the sound signal An are not limited to the above example. For example, the operation control unit 70 may control parameters of the sound processing for the sound signal An. For example, the present disclosure is also applicable to the control of various parameters related to the sound processing such as equalization processing, filtering processing, reverberation processing, and voice quality conversion processing.

[0076] (3) In the above embodiment, the feed amount Xn (and in the interlocking control mode, the feed amount Yn) is controlled in response to the operation Qx-n on the operation knob 51-n. However, the form of the physical operator used to control the feed amount Xn is arbitrary and is not limited to the above example. For example, a button-type or fader-type physical operator may be used to operate the feed amount Xn. Furthermore, the operator that accepts the operation Qx-n of the feed amount Xn is not limited to the physical operator exemplified above. For example, the feed amount Xn may be controlled in response to an operation on a touch panel mounted on the display device.

[0077] (4) In the above embodiment, the selection buttons 81-n are exemplified as virtual operators displayed on the display device 25. However, the selection buttons 81-n may be physical operators provided on the housing 50 of the sound processing device 10.

[0078] (5) In the above embodiment, the sound signal A-1 represents the voice of user U1, the sound signal A-2 represents the voice of user U2, and the sound signal A-3 represents the sound of a game, but the type of sound represented by each sound signal An is not limited to the above examples. For example, the sound signal A-1 may be a signal representing, for example, the voice of user U2 or the sound of a game. The sound signal A-2 may be a signal representing, for example, the voice of user U1 or the sound of a game. The sound signal A-3 may be a signal representing, for example, the voice of user U1 or user U2. Types of sound other than the above examples may be represented by the sound signal An.

[0079] In the above embodiment, the sound signal A-3 is supplied from the game device 33 to the sound processing device 10 via the input / output interface 16, but the source and route of the sound signal A-3 are not limited to the above example. For example, in a form in which the information processing device 20 provides a game to the user U1, the sound signal A-3 representing the sound of the game may be supplied from the information processing device 20 to the sound processing device 10. For example, the sound signal A-3 transmitted from the communication device 23 of the information processing device 20 is received by the communication device 13 of the sound processing device 10.

[0080] (6) In the above embodiment, the sound signal Bx represents the sound to be listened to by the user U1, and the sound signal By represents the sound to be distributed. However, the uses of the sound signals Bx and By are not limited to the above examples. For example, a form in which the sound signal Bx represents the sound to be distributed, and the sound signal By represents the sound to be listened to by the user U1, is also possible. In addition, one or both of the sound signals Bx and By may be recorded on a recording medium such as the storage device 12.

[0081] 10, a switching unit 67 may be provided in the sound processing device 10. The switching unit 67 switches the output source for the sound emitting device 32 (output adjustment unit 66) between the sound signal Bx and the sound signal By. For example, the switching unit 67 selects the output source for the sound emitting device 32 from the sound signal Bx and the sound signal By in response to an operation from the user U1 on the operation device 14 or the operation device 24. According to the above configuration, the sound signal By for distribution is reproduced by the sound emitting device 32, so that the user U1 can confirm it.

[0082] (7) In each of the above-described embodiments, an operating mode (individual control mode / interlocking control mode) is set individually for each pair of feed amount Xn and feed amount Yn. However, the operating mode may be set collectively for the three sound signals A-1 to A-3.

[0083] Also, the interlocking control mode may be set for some of the sound signals An among the three sound signals A-1 to A-3. For example, the operation control unit 70 controls the feed amounts Xn and Yn of two sound signals An among the three sound signals A-1 to A-3 in an interlocking manner in response to an operation by the user U1, and controls the feed amounts Xn and Yn of the remaining sound signal An individually.

[0084] (8) In the above embodiment, the feed amount Yn is set to the value of the current feed amount Xn at the stage of transition from the individual control mode to the interlocking control mode, but the timing at which the feed amount Yn is set to the value of the feed amount Xn is not limited to the time of transition to the interlocking control mode. For example, the feed amount Yn may be set to the value of the feed amount Xn at any time during operation in the interlocking operation mode or at the time when a transition to the individual control mode is instructed.

[0085] (9) In each of the above-described embodiments, two types of operation modes, the individual control mode and the interlocking control mode, are exemplified, but other operation modes may be included in the selection candidates. For example, in addition to the individual control mode and the interlocking control mode, an operation mode that prohibits changes in the feed amount Xn and the feed amount Yn may be selected. As can be understood from the above description, the operation control unit 70 selects one of a plurality of operation modes including the individual control mode and the interlocking control mode.

[0086] (10) The functions of the sound processing device 10 exemplified above are realized by the cooperation of one or more processors constituting the control device 11 and the program stored in the storage device 12, as described above. The program according to the present disclosure can be provided in a form stored in a computer-readable recording medium and installed in a computer. The recording medium is, for example, a non-transitory recording medium, and a good example is an optical recording medium (optical disk) such as a CD-ROM, but also includes any known type of recording medium such as a semiconductor recording medium or a magnetic recording medium. Note that the non-transitory recording medium includes any recording medium except for a transient propagating signal, and does not exclude a volatile recording medium. In addition, in a configuration in which the distribution device 41 distributes a program via the communication network 200, the storage medium that stores the program in the distribution device 41 corresponds to the non-transitory recording medium described above.

[0087] (11) In this application, the term "mth" (m is a natural number) is used only as a formal and convenient label to distinguish each element in the description and does not have any substantial meaning. Therefore, there is no room for restrictive interpretation of the arrangement or order of each element based on the term "mth".

[0088] C: Notes From the above-described exemplary embodiments, the following configurations can be understood, for example.

[0089] A control method for a sound processing device according to one aspect (aspect 1) of the present disclosure includes a first adjustment unit that adjusts a first sound signal in accordance with a first parameter, a second adjustment unit that adjusts the first sound signal in accordance with a second parameter, a third adjustment unit that adjusts the second sound signal in accordance with a third parameter, a fourth adjustment unit that adjusts the second sound signal in accordance with a fourth parameter, a first mixing unit that mixes a signal adjusted by the first adjustment unit and a signal adjusted by the third adjustment unit, and a second mixing unit that mixes a signal adjusted by the second adjustment unit and a signal adjusted by the fourth adjustment unit, wherein in a first operation mode, the first parameter is controlled in accordance with a first operation on a first operator, the second parameter is controlled in accordance with a second operation different from the first operation, the third parameter is controlled in accordance with a third operation on a second operator, and the fourth parameter is controlled in accordance with a fourth operation different from the third operation, and in a second operation mode, the first parameter and the second parameter are controlled in accordance with the first operation, and the third parameter and the fourth parameter are controlled in accordance with the third operation.

[0090] In the above aspect, in the first operation mode, the first parameter and the second parameter are individually controlled. Therefore, each of the first parameter and the second parameter can be precisely adjusted. On the other hand, in the second operation mode, the first parameter and the second parameter are controlled in response to the first operation on the first operator. That is, the first operation is used in common for the control of the first parameter and the control of the second parameter. Therefore, in the second operation mode, the second operation for adjusting the second parameter is not required. According to the above aspect, compared with the aspect in which only the individual control of the first parameter and the second parameter is allowed, the operation required for controlling the first parameter and the second parameter can be simplified. The same is true for the third parameter and the fourth parameter. As described above, in the second operation mode, the control of the first parameter and the second parameter in response to the first operation and the control of the third parameter and the fourth parameter in response to the third operation are executed, so that the adjustment of the mixing ratio in the first mixing section and the second mixing section is easy.

[0091] The "m-th parameter" (m=1 to 4) is a parameter applied to the adjustment of the m-th sound signal by the m-th adjustment unit. For example, the send level of the m-th sound signal is exemplified as the "m-th parameter".

[0092] The first operation is an operation on the first operator. On the other hand, the second operation is an operation different from the first operation on the first operator. For example, the second operation is an operation on an operator separate from the first operator. The operator that accepts the second operation may be an operator installed in the sound processing device, or an operator of a peripheral device connected to the sound processing device. In addition, the operator that accepts the second operation may be either a physical operator or a virtual operator. Although the above description focuses on the second operation, the same applies to the fourth operation.

[0093] In a specific example (aspect 2) of aspect 1, in the second operation mode, the first parameter and the second parameter are controlled in conjunction with each other in response to the first operation, and the third parameter and the fourth parameter are controlled in conjunction with each other in response to the second operation. In the above aspect, since the first parameter and the second parameter are controlled in conjunction with each other, it is easy to change both the first parameter and the second parameter according to the user's intention. The same applies to the third parameter and the fourth parameter.

[0094] In a specific example (aspect 3) of aspect 2, when the second operation mode is transitioned to the first operation mode, the link between the first parameter and the second parameter is released while maintaining the value of the second parameter immediately before the transition, and the link between the third parameter and the fourth parameter is released while maintaining the value of the fourth parameter immediately before the transition. In the above aspect, the second parameter immediately before the transition from the second operation mode to the first operation mode is maintained immediately after the transition to the first operation mode. Therefore, starting from the first parameter and the second parameter set in conjunction with each other in the second operation mode, the first parameter and the second parameter are each individually controlled after the transition to the first operation mode. That is, in the second operation mode, the second parameter is set to a target value (target value of the feed amount for the second mixing section) while the first and second parameters are linked, and then in the first operation mode, the first parameter is fine-tuned by the difference between the target value of the second parameter and the target value of the first parameter (target value of the feed amount for the first mixing section), thereby quickly and easily setting each of the first and second parameters to their target values. The same applies to the third and fourth parameters.

[0095] In a specific example (Aspect 4) of Aspect 2 or Aspect 3, when the first operation mode is transitioned to the second operation mode, the second parameter is set to the value of the first parameter immediately before the transition, and the fourth parameter is set to the value of the third parameter immediately before the transition. In the above aspect, the value of the first parameter set in the first operation mode is set as an initial value, and the second parameter can be adjusted in the second operation mode. Therefore, the operation for setting both the first parameter and the second parameter to target values ​​can be simplified.

[0096] In a specific example (Aspect 5) of any of Aspects 1 to 4, one of a plurality of operation modes including the first operation mode and the second operation mode is individually selected for each of the set of the first parameter and the second parameter and the set of the third parameter and the fourth parameter. In the above aspects, an operation mode (first operation mode / second operation mode) is individually set for each of the set of the first parameter and the second parameter and the set of the third parameter and the fourth parameter. Therefore, compared to a form in which the operation mode is collectively set for the first parameter to the fourth parameter, each of the first parameter to the fourth parameter can be diversified and set by a simple operation.

[0097] "Operation modes are set individually" means that operation modes are set independently for each of the set of the first and second parameters and the set of the third and fourth parameters. Therefore, for example, the first operation mode is selected for one of the set of the first and second parameters and the set of the third and fourth parameters, and the second operation mode is selected for the other.

[0098] In a specific example (Aspect 6) of any one of Aspects 1 to 5, the sound processing device further includes a fifth adjustment unit that adjusts a third sound signal in accordance with a fifth parameter, and a sixth adjustment unit that adjusts the third sound signal in accordance with a sixth parameter, the first mixing unit mixes a signal adjusted by the first adjustment unit, a signal adjusted by the third adjustment unit, and a signal adjusted by the fifth adjustment unit, the second mixing unit mixes a signal adjusted by the second adjustment unit, a signal adjusted by the fourth adjustment unit, and a signal adjusted by the sixth adjustment unit, and in the first operation mode, further controls the fifth parameter in accordance with a fifth operation on a fifth operator, and controls the sixth parameter in accordance with a sixth operation different from the fifth operation, and in the second operation mode, further controls the fifth parameter and the sixth parameter in accordance with the fifth operation. In the above aspects, the first sound signal, the second sound signal, and the third sound signal are mixed by the first mixing unit and the second mixing unit after adjustment of each parameter. Therefore, it is possible to generate two systems of signals in which the first sound signal, the second sound signal, and the third sound signal are mixed at different mixing ratios.

[0099] In a specific example (Aspect 7) of any one of Aspects 1 to 6, the first output signal after mixing by the first mixer is supplied to a sound emitting device, and the second output signal after mixing by the second mixer is transmitted to an information device via a communication network. In the above aspects, the first output signal is supplied to the sound emitting device and is heard by a user of the sound processing device. On the other hand, the second output signal is transmitted to an information device separate from the sound processing device. In other words, a first output signal for hearing by the user and a second output signal for transmission to the information device can be generated.

[0100] A sound processing device according to one embodiment (embodiment 8) of the present disclosure includes a first adjustment unit that adjusts a first sound signal in accordance with a first parameter, a second adjustment unit that adjusts the first sound signal in accordance with a second parameter, a third adjustment unit that adjusts the second sound signal in accordance with a third parameter, a fourth adjustment unit that adjusts the second sound signal in accordance with a fourth parameter, a first mixing unit that mixes a signal adjusted by the first adjustment unit and a signal adjusted by the third adjustment unit, a second mixing unit that mixes a signal adjusted by the second adjustment unit and a signal adjusted by the fourth adjustment unit, and an operation control unit, wherein in a first operation mode, the operation control unit controls the first parameter in accordance with a first operation on a first operator, controls the second parameter in accordance with a second operation different from the first operation, controls the third parameter in accordance with a third operation on a second operator, and controls the fourth parameter in accordance with a fourth operation different from the third operation, and in a second operation mode, controls the first parameter and the second parameter in accordance with the first operation, and controls the third parameter and the fourth parameter in accordance with the third operation.

[0101] In a specific example (aspect 9) of aspect 8, a housing is provided that houses the first adjustment unit, the second adjustment unit, the third adjustment unit, the fourth adjustment unit, the first mixing unit, and the second mixing unit, and the first operation and the third operation are operations on a physical operator installed on the housing, and the second operation and the fourth operation are operations on a virtual operator displayed on a display device. As described above, in the second operation mode, the first parameter and the second parameter are controlled in conjunction with each other in response to the first operation on the first operator, so that a physical operator dedicated to adjusting the second parameter (second operation) is not required for the sound processing device. Therefore, it is easier to reduce the size of the housing of the sound processing device compared to a configuration in which a physical operator for the second operation is installed in addition to the first operator for the first operation.

[0102] A "physical operator" is a tangible user interface that a user can actually touch in real space. Examples of "physical operators" include various operators such as buttons, switches, knobs, and keys. On the other hand, a "virtual operator" is a virtual user interface realized by software. For example, a GUI (Graphical User Interface) such as a virtual operator displayed on a display device is an example of a "virtual operator".

[0103] In a specific example (aspect 10) of aspect 9, a selection operator for selecting the first operation mode or the second operation mode is provided, and the selection operator is a virtual operator displayed on the display device. According to the above aspect, the selection operator for selecting the first operation mode or the second operation mode does not need to be installed as a physical operator on the housing. Therefore, it is easier to reduce the size of the housing compared to a configuration in which a physical operator for selecting an operation mode is installed on the housing of the sound processing device.
