[0022] Figure 1 1 is a block diagram showing the configuration of an acoustic system. The acoustic system 100 includes a mixer 11 , an information processing terminal 12 , an I / O device 13 , a plurality of speakers 14 , and a plurality of microphones 15 .

[0023] The mixer 11 and the I / O device 13 are connected via a network cable. The I / O device 13, the plurality of speakers 14, and the plurality of microphones 15 are connected via an audio cable. The information processing terminal 12 is connected to the mixer 11 via wireless communication.

[0024] However, in the present invention, the connection between devices is not limited to the above examples. For example, the mixer 11 and the information processing terminal 12 can also be connected via a USB cable, HDMI (registered trademark), or MIDI communication line. In addition, the mixer 11 and the I / O device 13 can also be connected via an audio cable.

[0025] The mixer 11 is an example of the sound processing device of the present invention. The mixer 11 receives an audio signal from the I / O device 13 or outputs an audio signal to the I / O device 13. In addition, the sound processing device is not limited to the mixer 11. For example, a system composed of hardware or software for performing operations such as recording, editing, or mixing audio (DAW: Digital Audio Workstation) is also an example of the sound processing device.

[0026] Figure 2 It is a block diagram showing the structure of the I / O device 13. Figure 3 : is a block diagram showing the structure of the mixer 11. Figure 4 This is a block diagram functionally showing a signal processing unit. Figure 5 It is a block diagram showing the structure of the information processing terminal 12.

[0027] The I / O device 13 includes a display 101 , a user interface (I / F) 102 , an input / output terminal 103 , a flash memory 104 , a RAM 105 , a network interface (I / F) 106 , and a CPU 107 .

[0028] The display 101 , the user interface (I / F) 102 , the audio interface (I / F) 103 , the flash memory 104 , the RAM 105 , the network interface (I / F) 106 , and the CPU 107 are connected to the bus 151 .

[0029] The display 101 is composed of, for example, an LCD (Liquid Crystal Display) or an OLED (Organic Light-Emitting Diode), and displays various information. The user I / F 102 is composed of a switch, a knob, or a touch panel, and receives user operations. When the user I / F 102 is a touch panel, the user I / F 102 and the display 101 together constitute a GUI (Graphical User Interface, hereinafter omitted).

[0030] The CPU 107 reads the program stored in the flash memory 104 as a storage medium into the RAM 105 to implement the specified function. In addition, the program read by the CPU 107 does not need to be stored in the flash memory 104 in the device. For example, the program may also be stored in a storage medium of an external device such as a server. In this case, the CPU 107 may also read the program from the server to the RAM 105 each time and execute it.

[0031] Figure 6 1 is a diagram showing the appearance of the I / O device 13. As an example, the I / O device 13 has a rectangular parallelepiped housing. Figure 61 is a diagram showing a front panel of a housing. A display 101, input / output terminals 103, and a network I / F 106 are arranged on the front panel of the housing. In addition, a user I / F 102 composed of a touch panel is stacked on the display 101.

[0032] The display 101 displays the model name of the I / O device 13 ( Figure 6 However, the model name does not need to be displayed on the display 101. The model name may also be printed or engraved on a part of the housing.

[0033] The input / output terminal 103 is composed of a plurality of input / output terminals. Figure 6 In the example of , the input / output terminal 103 has 8×3, i.e., 24 input terminals. Each input terminal is connected to the microphone 15. A sound signal is input to each input terminal from the microphone 15. In addition, the input / output terminal 103 has 8 output terminals. Each output terminal is connected to the speaker 14. Each output terminal outputs a sound signal to the speaker 14. In addition, the number of terminals is not limited to this example.

[0034] CPU 107 transmits the audio signal input from each input terminal of input / output terminal 103 to mixer 11 via network I / F 106. CPU 107 also outputs the audio signal received from mixer 11 via network I / F 106 to each output terminal of input / output terminal 103.

[0035] The mixer 11 includes a display 201 , a user I / F 202 , an audio I / O (Input / Output) 203 , a signal processing unit (DSP) 204 , a network I / F 205 , a CPU 206 , a flash memory 207 , and a RAM 208 . These components are connected via a bus 171 .

[0036] The CPU 206 is a control unit that controls the operation of the mixer 11. The CPU 206 reads a predetermined program stored in the flash memory 207 as a storage medium into the RAM 208 and executes the program, thereby performing various operations.

[0037] In addition, the program read by the CPU 206 does not need to be stored in the flash memory 207 in the device. For example, the program can also be stored in a storage medium of an external device such as a server. In this case, the CPU 206 can also read the program from the server to the RAM 208 and execute it each time.

[0038] The signal processing unit 204 is composed of a DSP for performing various signal processing. The signal processing unit 204 performs signal processing such as mixing processing and filtering processing on the audio signal input from the I / O device 13 or other devices via the audio I / O 203 or the network I / F 205. The signal processing unit 204 outputs the audio signal after the signal processing to other devices such as the I / O device 13 via the audio I / O 203 or the network I / F 205.

[0039] Figure 4 2 is a functional block diagram showing signal processing implemented by the signal processing unit 204 and the CPU 206. Figure 4 As shown, signal processing is functionally performed through an input port (Patch) 401 , an input channel 402 , a bus 403 , an output channel 404 , and an output port 405 .

[0040] The input channel 402 has a signal processing function for 24 channels as an example. The input port 401 allocates each input terminal of the I / O device 13 to any channel of the input channel 402 .

[0041] An audio signal is supplied from the input port 401 to each channel of the input channel 402. Each channel of the input channel 402 performs various signal processing on the input audio signal. In addition, each channel of the input channel 402 sends the audio signal after the signal processing to the bus 403 of the subsequent stage.

[0042] The bus 403 mixes the input audio signals and outputs them. The bus 403 includes a plurality of buses such as an STL (stereo L) bus, a STR (stereo R) bus, an AUX bus, and a MIX bus.

[0043] The output channel 404 performs signal processing on each audio signal output from a plurality of buses. The output port 405 distributes each channel of the output channel 404 to each output terminal of the I / O device 13. The output port 405 sends the audio signal to the I / O device 13 via the audio I / O 203 or the network I / F 205.

[0044] The information processing terminal 12 is an information processing device such as a personal computer, a smartphone, or a tablet PC, etc. The information processing terminal 12 includes a display 301 , a user I / F 302 , a CPU 303 , a network I / F 305 , a flash memory 306 , a RAM 307 , and a camera 308 .

[0045] A user I / F 302 composed of a touch panel is stacked on the display 301 to form a GUI. The CPU 303 reads the program stored in the flash memory 306 as a storage medium into the RAM 307 to implement the specified function. In addition, the program read by the CPU 303 does not need to be stored in the flash memory 306 in the device. For example, the program can also be stored in the storage medium of an external device such as a server. In this case, the CPU 303 can also read the program from the server to the RAM 307 each time and execute it.

[0046] The CPU 303 configures the recognition unit 371 , the arrangement data generation unit 372 , the acquisition unit 373 , and the display processing unit 374 through the above-mentioned program.

[0047] Figure 7 303 is a flowchart showing the operation of the CPU 303. The recognition unit 371 of the CPU 303 first recognizes the model of the I / O device 13 (S11). Specifically, the recognition unit 371 extracts information about the model name from the image data captured by the camera 308, and recognizes the model based on the extracted model name. The user uses the camera 308 of the information processing terminal 12 to capture the front panel of the housing of the I / O device 13. The recognition unit 371 extracts information corresponding to the model name through image recognition processing. Figure 6 In the example of , the model name is displayed on the display 101. Therefore, the recognition unit 371 extracts the model name of "A0001". In addition, the recognition unit 371 may send the image data to the server and extract the corresponding model name on the server, thereby identifying the model. In addition, when the information of the model name is not displayed on the housing, the recognition unit 371 may also identify the model through image recognition processing. In this case, the recognition unit 371 infers the model that is most similar to the image data taken by the camera 308 and identifies the model.

[0048] Next, the configuration data generation unit 372 of the CPU 303 generates configuration data representing the configuration of the plurality of input / output terminals based on the recognition result of the recognition unit 371 (S12). The flash memory 306 stores the configuration data of each model in advance. The configuration data generation unit 372 refers to the flash memory 306 and reads the corresponding configuration data using the recognition result, i.e., the information of the model name. The configuration data includes information representing the number of input / output terminals, information representing the name of each input / output terminal, and information representing the position of each input / output terminal. The position of the input / output terminal is shown, for example, in rectangular coordinates with a predetermined position of the I / O device 13 (e.g., the lower left position when the front panel is viewed from the front) as a reference.

[0049] In addition, the configuration data generation unit 372 can also download the configuration data from the server. The server stores the configuration data of each model. The configuration data generation unit 372 sends the identification result, that is, the model name information to the server. The server replies with the configuration data corresponding to the received model name information.

[0050] On the other hand, the acquisition unit 373 of the CPU 303 acquires the sound processing parameters corresponding to each of the plurality of input and output terminals (S13). The sound processing parameters are, for example, channel name, gain, on / off of phantom power, polarity, content of signal processing (e.g., filter processing), on / off of CUE, etc. The acquisition unit 373 acquires the sound processing parameters for each of the plurality of input and output terminals from the mixer 11. For example, the acquisition unit 373 acquires the allocation information of the input port 401.

[0051] The display processing unit 374 displays the sound processing parameters corresponding to each of the plurality of input and output terminals on the display 301 based on the configuration data generated in S12 (S14). Figure 8 As shown, the display processing unit 374 displays the channel name at each position of the plurality of input and output terminals in the image of the front panel of the I / O device 13. The image of the front panel of the I / O device 13 may be pre-stored in the flash memory 306 or downloaded from the server. In addition, the image of the front panel of the I / O device 13 may be an image taken by the camera 308. When the image taken by the camera 308 is used, the display processing unit 374 displays the sound processing parameter in a superimposed manner on the image currently taken by the camera 308.

[0052] exist Figure 8 In the example of , the input channel with the channel name of Vocal corresponds to the first input terminal. Therefore, the display processing unit 374 displays the channel name of Vocal on the first input terminal. In addition, in this example, the user inputs the channel name to each input channel in advance. However, if the user does not input the channel name, the display processing unit 374 may display the channel name such as "input channel 1" on each input / output terminal.

[0053] Thus, the user can easily understand which audio processing parameter is assigned to which input / output terminal. In addition, if the assignment is changed in the mixer 11, the display processing unit 374 also displays the changed content on the display 301. Therefore, even if the assignment is changed, the user can easily understand the content of the audio processing parameter assigned to each input / output terminal.

[0054] (Variant 1)

[0055] In the above example, the recognition unit 371 recognizes the model based on the image of the front panel of the I / O device 13 captured by the camera 308. However, the recognition unit 371 may acquire the model information from the I / O device 13 using, for example, a predetermined communication function. Fig. 9 This is a diagram showing the appearance of an I / O device 13 and an information processing terminal 12 according to Modification 1.

[0056] exist Fig. 9 In the example, NFC is used as the communication interface. Fig. 9 As shown, NFCI / F502 is, for example, provided at a part of the housing of the I / O device 13. NFCI / F is an example of a communication interface, and communicates with other devices via an antenna. The NFC standard limits the communicable distance to a very close distance such as 10 cm. Therefore, NFC can only communicate with devices at very close distances. Of course, the communication interface is not limited to NFC. For example, the housing of the I / O device 13 may also have a Bluetooth (registered trademark) low energy beacon. The information processing terminal 12 may also obtain information on the model name using Bluetooth (registered trademark).

[0057] like Fig. 9 As shown, the user brings the information processing terminal 12 close to the housing of the I / O device 13. In this case, the information processing terminal 12 also has an NFC I / F. The identification unit 371 obtains the model name information from the I / O device 13 via NFC. Thus, the identification unit 371 can also identify the model.

[0058] (Variant 2)

[0059] Fig.10 and Fig.11 This is a display example of the display 301 according to Modification 2. A user I / F 302 composed of a touch panel is stacked on the display 301 to form a GUI. The user I / F 302 receives an operation on an audio processing parameter by a user via the touch panel.

[0060] For example, when the user touches the display 301, the display processing unit 374 displays Fig.10 and Fig.11 The "INPUT INFO" screen shown in the figure. "INPUT INFO" is a screen for display switching operations. Fig.10 In the example shown in the figure, "INPUTINFO" contains "NAME", "GAIN", "+48V", "POLARITY" and "FILTER". "NAME" indicates the channel name. "GAIN" indicates the gain. "+48V" indicates the phantom power. "POLARITY" indicates the polarity. "FILTER" indicates the filter.

[0061] Here, as a display switching operation, the user selects "GAIN", for example. Fig.11 As shown in FIG. 1 , the display processing unit 374 displays gain instead of channel name as the sound processing parameter. Fig.11 In the example of FIG. 3 , the display processing unit 374 displays the value of the gain and the level indicator (Level gauge). The gain may be only a value or only a level indicator. Fig.12 As shown, the display processing unit 374 may display both the channel name and the level indicator. This allows the user to view the gain of each input and output terminal at a glance.

[0062] In addition, the switching of the display is not limited to the above-mentioned example. For example, the display processing unit 374 may also display a preview of a scene review. The scene review is a process of reading the scene data stored in the flash memory 207 of the mixer 11. If the user performs a scene review, the content of the sound processing parameter changes. The preview display of the scene review is a function of changing only the content of the sound processing parameter displayed on the display 301 while maintaining the sound processing parameter of the mixer 11 unchanged. If the user performs a preview display operation of the scene review, the information processing terminal 12 receives the corresponding scene data from the mixer 11. The display processing unit 374 displays the content of the sound processing parameter corresponding to the scene data at the position of each input and output terminal of the display 301. Thus, the user can understand how the content of the sound processing parameter will change when the scene review is performed. At this time, since the content of the signal processing of the mixer 11 has not changed, the user can easily understand the content of the sound processing parameter even in a state where the sound is not switched during a formal performance of a concert.

[0063] (Variant 3)

[0064] Fig.13 3 is a display example of the display 301 according to the modification example 3. The information processing terminal 12 of the modification example 3 can set the mixer 11. For example, when the user touches the position of each input / output terminal displayed on the display 301, the display processing unit 374 displays the following information: Fig.13 The setting screen of each input and output terminal is shown.

[0065] exist Fig.13 In the example, input terminal 1 is touched. Display processing unit 374 displays a setting screen "IN1: Vocal" for input terminal 1. The setting screen includes "PATCH", "NAME", "GAIN", "+48V", "POLARITY", "FILTER", "EDIT", "CUE", and "CANCEL".

[0066] If the user touches "PATCH", the input channel assigned to the input terminal 1 can be changed. If the user changes the input channel assigned to the input terminal 1, the information processing terminal 12 sends information indicating the input channel to be assigned to the mixer 11. The mixer 11 changes the assignment of the input port 401 based on the received information.

[0067] If the user touches "NAME", the channel name can be changed. In this case, the allocation of the input port 401 is not changed, and only the channel name is changed.

[0068] If the user touches "GAIN", the gain can be changed. If the display processing unit 374 receives the touch of "GAIN", it displays, for example, a knob or a volume controller. The information processing terminal 12 receives the gain change operation by receiving the operation of the knob or the volume controller. The information processing terminal 12 sends the information of the changed gain to the mixer 11. The mixer 11 changes the allocation of the input port 401 based on the received gain information.

[0069] If the user touches "+48V", the phantom power can be turned on / off. If the user touches "POLARITY", the polarity can be reversed. If the user touches "FILTER", the screen can be switched to the filter setting screen to turn the filter on / off and set the filter characteristics.

[0070] When the user touches "EDIT", the screen jumps to the channel setting screen. The channel setting screen allows setting of, for example, the content of signal processing, the destination of the audio signal, the transmission amount, etc.

[0071] When the user touches "CUE", the CUE can be turned on or off. When the CUE is turned on, the audio signal of the corresponding channel is sent to the user's monitoring headphones.

[0072] If the user touches "CANCEL", the setting screen closes.

[0073] exist Fig.13 Although an example in which the contents of the sound processing parameters of the input terminals and the input channels are changed is shown, the contents of the sound processing parameters of the mixer 11 can be changed similarly in the output terminals and the output channels.

[0074] (Variant 4)

[0075] In the examples described above, the recognition unit 371 extracts information about the model name from the image data captured by the camera 308, and recognizes the model based on the extracted model name. However, the recognition unit 371 may recognize the model based on, for example, the unit ID of the user or inherent information (manufacturing number) of each device instead of the model name. In addition, the unit ID refers to a management number (for example, an alphanumeric number) inherently assigned to each of the multiple devices constituting the audio system 100 in the audio system 100. The unit ID may be manually assigned to each device by the user using a device (for example, the mixer 11) as a host, or may be automatically assigned by the device as a host. Thus, the recognition unit 371 can distinguish between the individual I / O devices even when using multiple I / O devices of the same model.

[0076] The description of the present embodiment is illustrative in all aspects and is not restrictive. The scope of the present invention is not represented by the above-mentioned embodiment but by the claims. Moreover, the scope of the present invention includes all changes within the meaning equivalent to the claims and the scope.

[0077] For example, the operation accepting unit may also accept the user's operation through voice recognition processing. In addition, the information processing terminal may also be a head-mounted information processing terminal. In this case, the operation accepting unit of the information processing terminal recognizes the user's gesture and accepts the operation corresponding to the user's gesture.
