[0004] In the acoustic parameter editing method of Patent Document 1, information such as the model of the signal processing engine (the acoustic device to be edited) is pre - characterized.

[0005] Therefore, an object of one embodiment of this invention is to provide an acoustic parameter editing method that can edit acoustic parameters offline without specifying information about the acoustic device to be edited.

Means for Solving the Problems

[0006] The acoustic parameter editing method is an acoustic parameter editing method for an acoustic system comprising: a plurality of acoustic devices having an acoustic signal processing engine for performing acoustic signal processing; and a management device for editing the acoustic parameters of the acoustic signal processing performed by the plurality of acoustic devices. The management device accepts the editing of the acoustic parameters when the plurality of acoustic devices are not connected, and the management device or the plurality of acoustic devices acquire correspondence information between a first acoustic parameter stored in the memory of the plurality of acoustic devices and a second acoustic parameter stored in the memory of the management device. When any of the plurality of acoustic devices is connected to the management device, the management device or the connected acoustic device changes the second acoustic parameter to the first acoustic parameter based on the correspondence information. [Effects of the Invention]

[Figure 11] Another example of a manager tool is the GUI screen for calculating the placement distribution of acoustic devices for a given input condition. [Figure 12] This is a state transition diagram for the GUI. [Figure 13] This figure shows an example of a GUI (system settings screen) for searching for acoustic devices and displaying the search results. [Figure 14] This diagram shows the GUI when the first network interface is accepted. [Figure 15] This diagram shows the GUI after the selection of the first protocol (UID) has been accepted. [Figure 16] This diagram shows the GUI after the audio device to be connected has been specified. [Figure 17] This diagram shows the GUI when the selection of the second protocol (TCP) is accepted. [Modes for carrying out the invention]

[0009] Figure 1 is a block diagram showing the configuration of the sound system 1. The sound system 1 comprises a mixer 11, a control device 12, a network 13, a speaker 14, and a microphone 15. The mixer 11, speaker 14, and microphone 15 are examples of multiple sound devices having a sound signal processing engine for processing sound signals in the present invention.

[0010] The mixer 11, management device 12, speaker 14, and microphone 15 are connected via a network 13 such as a LAN. However, in the present invention, the connections between devices are not limited to this example. For example, the mixer 11, management device 12, speaker 14, and microphone 15 may be connected by an audio cable, a USB cable, or wireless communication.

[0011] The mixer 11 receives an audio signal from the microphone 15. Also, the mixer 11 outputs the audio signal to the speaker 14. In this embodiment, the speaker 14 and the microphone 15 are shown as examples of acoustic devices connected to the mixer 11, but actually, a number of acoustic devices are connected to the mixer 11. The mixer 11 receives audio signals from a plurality of acoustic devices such as the microphone 15, performs audio signal processing such as mixing, and outputs the audio signal to a plurality of acoustic devices such as the speaker 14.

[0012] FIG. 2 is a block diagram showing the configuration of the mixer 11. 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.

[0013] The CPU 206 is a control unit that controls the operation of the mixer 11. The CPU 206 performs various operations by reading a predetermined program stored in the flash memory 207, which is a storage medium, into the RAM 208 and executing it.

[0014] Note that the program read by the CPU 206 does not necessarily need to be stored in the flash memory 207 within the device itself. For example, the program may be stored in a storage medium of an external device such as a server. In this case, the CPU 206 may read the program from the server into the RAM 208 and execute it each time.

[0015] The signal processing unit 204 is composed of a DSP for performing various audio signal processes. The signal processing unit 204 performs audio signal processes such as mixing processing and filter processing on the audio signal input from an acoustic device such as the microphone 15 via the audio I / O 203 or the network I / F 205. The signal processing unit 204 outputs the processed audio signal to an acoustic device such as the speaker 14 via the audio I / O 203 or the network I / F 205.

[0016] The user sets the acoustic parameters (first acoustic parameters) for sound signal processing in the mixer 11 via the user interface 202. The set first acoustic parameters are stored in the flash memory 207 or RAM 208. The signal processing unit 204 and CPU 206 perform sound signal processing based on the first acoustic parameters stored in the flash memory 207 or RAM 208.

[0017] Next, Figure 3 is a block diagram showing the configuration of the management device 12. The management device 12 consists of, for example, a personal computer or a dedicated embedded system.

[0018] The management device 12 includes a display 301, a user interface 302, a CPU 303, RAM 304, a network interface 305, and flash memory 306.

[0019] The CPU 303 reads a program stored in the flash memory 306, which is the storage medium, into the RAM 304 to perform a predetermined function. Note that the program read by the CPU 303 does not necessarily have to be stored in the flash memory 306 within the device itself. For example, the program may be stored in the storage medium of an external device such as a server. In this case, the CPU 303 can simply read the program from the server into the RAM 304 each time and execute it.

[0020] The flash memory 306 stores, for example, a GUI program. The management device 12 executes the GUI program to provide the user with a GUI.

[0021] Figure 4 shows an example of a GUI. The GUI shown in Figure 4 is a manager tool for accepting settings of acoustic parameters for each signal processing component. A signal processing component refers to a functional configuration that receives an audio signal, performs predetermined audio signal processing on the received audio signal, and outputs an audio signal. In the example in Figure 4, the signal processing components include audio signal processing components such as the input component 502, attenuator (ATT) 503, mixing component (Mix) 504, amplifier 505, and output component 506. Through such a GUI program, the user can edit the acoustic parameters of the audio signal processing to be performed by each audio device such as the mixer 11. For example, in the example in Figure 4, the input component 502 has set an acoustic parameter to turn on the first channel and an acoustic parameter to turn off the second channel.

[0022] The GUI program may be a native application program running on the operating system of the management device 12, or it may be a web application program, for example. If the GUI program is a web application program, the user receives the GUI from the GUI program via a web browser application program.

[0023] Acoustic parameters edited with the manager tool are stored as second acoustic parameters in flash memory 306 or RAM 304. The contents of flash memory 306 or RAM 304 are synchronized with the flash memory 207 or RAM 208 of the mixer 11 when connected to the mixer 11. For example, when a user changes the second acoustic parameter via a GUI program, the CPU 303 updates the contents of flash memory 306 or RAM 304 and sends the updated second acoustic parameter to the mixer 11. The mixer 11 synchronizes the first acoustic parameter with the second acoustic parameter. This allows the user to edit the first acoustic parameter via the management device 12.

[0024] Furthermore, for example, if a user changes the first acoustic parameter by operating the user interface 202 of the mixer 11, the mixer 11 updates the contents of the flash memory 207 or RAM 208 and sends the updated first acoustic parameter to the management device 12. The CPU 303 receives the first acoustic parameter via the network interface 305 and synchronizes the contents of the flash memory 306 or RAM 304 as the second acoustic parameter. This also allows the user to directly edit the first acoustic parameter.

[0025] The control device 12 can edit the second acoustic parameter even when it is not connected to an acoustic device such as the mixer 11.

[0026] Figure 5 is a flowchart illustrating the operation of the management device 12. The management device 12 accepts editing of the second acoustic parameter when the acoustic device is offline and not connected (S11). For example, the management device 12 accepts editing of the acoustic parameter of the signal processing component via the manager tool shown in Figure 4.

[0027] Conventional manager tools accepted the specification of the model (type and model name) of the audio device to be edited while it was online, and then accepted the editing of the acoustic parameters of the signal processing component corresponding to the specified model. Therefore, conventional manager tools accepted the editing of acoustic parameters on the premise that the device was online. Alternatively, Japanese Patent Publication No. 2022-85045 accepted offline editing when the model of the audio device to be edited was specified in advance. However, the management device 12 of this embodiment accepts the editing of acoustic parameters of the signal processing component even when offline, without specifying the model of the target audio device.

[0028] Next, the management device 12 acquires correspondence information between the first acoustic parameter and the second acoustic parameter (S12). Figure 6 shows an example of the correspondence information. The correspondence information shows the relationship between the second acoustic parameter accepted by the manager tool of the management device 12 and the first acoustic parameter for each acoustic device. In the example in Figure 6, the acoustic parameter includes information about sound input and output. The correspondence information is configured to change the second acoustic parameter to the first acoustic parameter so that the sound input and output in sound signal processing become the sound input and output specified by the second acoustic parameter.

[0029] For example, in the manager tool example in Figure 4, an acoustic parameter is set to turn on the first channel and an acoustic parameter is set to turn off the second channel in the input component 502. In this manager tool, the "on" acoustic parameter means turning on the input and output of the sound signal, and the "off" acoustic parameter means turning off the input and output of the sound signal. In contrast, in a certain acoustic device A, the "on" acoustic parameter means turning on mute, and the "off" acoustic parameter means turning off mute. In other words, the on and off acoustic parameters edited in the manager tool of the management device 12 and the on and off acoustic parameters in acoustic device A have opposite meanings. Therefore, the mapping information shown in Figure 6 maps the "on" acoustic parameter of the management device 12 to the "off" acoustic parameter of acoustic device A, and the "off" acoustic parameter of the management device 12 to the "on" acoustic parameter of acoustic device A. Also, the on and off acoustic parameters of a certain acoustic device B have the same meaning as the on and off acoustic parameters edited in the manager tool of the management device 12. Therefore, the mapping information shown in Figure 6 associates the "on" acoustic parameter of the control device 12 with the "on" acoustic parameter of acoustic device B, and associates the "off" acoustic parameter of the control device 12 with the "off" acoustic parameter of acoustic device B. In addition, the acoustic parameter of acoustic device C is represented by a variable from 0 to 1. Acoustic device C is off with an acoustic parameter of "0.0" and on with acoustic parameters other than "0.0". Therefore, the mapping information shown in Figure 6 associates the "on" acoustic parameter of the control device 12 with an acoustic parameter of, for example, "1.0" of acoustic device C, and associates the "off" acoustic parameter of the control device 12 with an acoustic parameter of "0.0" of acoustic device C. Note that the "off" acoustic parameter does not necessarily have to be associated with "0.0". For example, the "off" acoustic parameter may be associated with a volume value that is inaudible to the human ear (for example, a value between 0.0 and 0.5), and the "on" acoustic parameter may be associated with any other value.

[0030] The management device 12 then checks whether any of the multiple sound devices are connected (S13). If the management device 12 determines that a sound device is connected (if S13 is YES), it changes the second sound parameter to the first sound parameter based on the correspondence information (S14). If the management device 12 determines that no sound device is connected (if S13 is NO), it returns to the process in S11. After changing the second sound parameter to the first sound parameter, the management device 12 transmits the first sound parameter to the target sound device (S15). The sound device receives the first sound parameter and stores the received first sound parameter in flash memory or RAM.

[0031] This allows users to edit acoustic parameters offline without having to specify information such as the model name of the acoustic device being edited, providing a new customer experience.

[0032] (Variation 1) Figure 7 is a flowchart showing the operation of the control device 12 according to Modification 1, and Figure 8 is a flowchart showing the operation of the mixer 11 according to Modification 1.

[0033] In the modified example 1, the management device 12 accepts editing of the second acoustic parameter while offline and no acoustic device is connected (S11), and then checks whether any of the multiple acoustic devices are connected (S13). If the management device 12 determines that an acoustic device is connected (if S13 is YES), it sends the second acoustic parameter to the target acoustic device (mixer 11 in this example) (S104).

[0034] Mixer 11 receives a second acoustic parameter from the control device 12 (S21). Mixer 11 acquires correspondence information between the first acoustic parameter and the second acoustic parameter (S22). Based on the acquired correspondence information, Mixer 11 changes the second acoustic parameter to the first acoustic parameter (S23). Mixer 11 stores the first acoustic parameter in flash memory or RAM (S24).

[0035] Thus, instead of the management device 12, the acoustic device may acquire the correspondence information and convert the second acoustic parameter to the first acoustic parameter.

[0036] Furthermore, for some acoustic devices, the management device 12 may convert the second acoustic parameter to the first acoustic parameter, while for other acoustic devices, the acoustic device itself may convert the second acoustic parameter to the first acoustic parameter. This prevents the management device 12 from being overloaded with conversion processing.

[0037] (Modification 2) Figure 9 shows the correspondence information related to Modification Example 2. The correspondence information related to Modification Example 2 shows the correspondence between the second acoustic parameter received by the manager tool of the management device 12 and the first acoustic parameter for each acoustic device. The acoustic parameter related to Modification Example 2 includes information on sound localization. The correspondence information related to Modification Example 2 is configured to change the second acoustic parameter to the first acoustic parameter so that the sound localization in sound signal processing becomes the sound localization specified by the second acoustic parameter.

[0038] For example, the localization information of the management device 12 in the correspondence information of Figure 9 is represented by a three-dimensional physical position (range: -50.0m to +50.0m) relative to a certain position. The localization information of the management device 12 for sound source A in Figure 9 is represented by three-dimensional physical position coordinates (x,y,z)=(+25,0,-25). In contrast, acoustic device A is represented by logical position coordinates linearly interpolated from the physical position coordinates. For example, the localization information of sound source A in Figure 9 is represented by (x,y,z)=(+0.5,0,-0.5) for acoustic device A. The localization information of acoustic device B is represented by the same physical coordinates as the localization information of the management device 12. Therefore, the localization information of sound source A shown in Figure 9 is represented by physical position coordinates (x,y,z)=(+25,0,-25) for acoustic device B. The localization information of acoustic device C is expressed in the same physical coordinates as the localization information of management device 12, but the range is -100.0m to +100.0m. Therefore, the localization information of sound source A shown in Figure 9 is expressed in acoustic device C as physical position coordinates (x,y,z)=(+50,0,-50).

[0039] The management device 12 or the acoustic device acquires such correspondence information and determines localization information based on the correspondence information.

[0040] (Variation 3) Figure 10 shows the correspondence information related to Modification 3. The acoustic parameters related to Modification 3 include information about volume. The correspondence information related to Modification 3 changes the second acoustic parameter to the first acoustic parameter so that the volume in the sound signal processing becomes the volume specified by the second acoustic parameter.

[0041] Figure 11 shows a GUI screen for calculating the placement distribution of acoustic devices for a given input condition, as another example of a manager tool. This manager tool uses a predetermined trained model to input the received acoustic space and the target signal-to-noise ratio (SNR) distribution (dB value) within that acoustic space, and determines the placement distribution of acoustic devices such as microphones and speakers corresponding to the SNR distribution. The volume (W) of each microphone and speaker relative to the target SNR (dB value) changes depending on the efficiency of each acoustic device. Therefore, as shown in Figure 10, the correspondence information related to Modification 3 shows the volume (W) of each microphone and speaker that results in the target dB value, based on the efficiency of each acoustic device.

[0042] The control device 12 or the sound device acquires such correspondence information and, based on the correspondence information, obtains information regarding the volume of each sound device.

[0043] (Modification 4) The acoustic system according to Modification 4 relates to a GUI for searching for and connecting acoustic devices in the above embodiments and Modifications 1 to 3. Figure 12 is a state transition diagram of the GUI. Figure 13 is a diagram showing an example of a GUI (system settings screen) for displaying the method of searching for acoustic devices and the search results. In the GUI according to Modification 4, a series of operations from selecting a device search using different protocols, displaying the results, and transitioning to online can be performed within a single screen without screen transitions.

[0044] The GUI includes a network adapter (NIC: Network Interface Card) selection screen, a device discovery screen, and a component list display screen. The user first selects the NIC to connect to the audio device. The NICs displayed are those connected to the router and assigned a local IP address. In the example in Figure 13, the first network interface is displayed with the NIC name "Network1" and the assigned IP address "192.168.0.199", and the second network interface is displayed with the NIC name "Network2" and the assigned IP address "192.168.0.200".

[0045] When the user selects a NIC, the GUI accepts the selection of a device discovery method on the device discovery screen. Figure 14 shows the GUI when the first network interface is accepted. When the management device 12 accepts a network interface, it accepts the selection of either the first or second protocol via the GUI. In this example, the first protocol is UID (UnitID), and the second protocol is TCP (Transmission Control Protocol).

[0046] Furthermore, it is preferable that the management device 12, upon receiving the selection of either the first or second network interface, initiates the search for acoustic devices using the first and second protocols, before receiving the selection of a protocol. This allows the search results to be displayed as soon as the user selects a method for searching for acoustic devices, thereby reducing the user's waiting time.

[0047] When the management device 12 receives a selection of the first protocol (UID), it displays a list of acoustic devices discovered by the first protocol on the display 301 as a result of the UID search, and displays a first operator for specifying the acoustic device to connect to. The UID search is performed by multicast using the specified network interface UDP.

[0048] Figure 15 shows the GUI after the selection of the first protocol (UID) has been accepted. As shown in Figure 15, the management device 12 displays a list of three acoustic devices, "MIX7", "MIX10", and "MIX30", as a result of the acoustic device discovery using the UID. As the first operator, the management device 12 accepts the specification of the acoustic device to be connected from among the multiple acoustic devices displayed in the list.

[0049] Furthermore, it is desirable that the UID search continue until the network interface is re-selected. Once the network interface is re-selected, the management device 12 starts a UID search for the re-selected network interface. It is also desirable that the UID search continue even after the GUI (system settings screen) is closed.

[0050] The management device 12 can add a new audio device to the list when it is powered on and becomes connectable by continuing to search by UID. The management device 12 may also periodically remove audio devices that are no longer connected from the list by performing UID searches.

[0051] When the management device 12 receives a specification of the audio device to be connected, it communicates with the specified audio device via TCP and synchronizes with some of the parameters of the audio device. That is, the management device 12 or the audio device synchronizes by changing the second audio parameter to the first audio parameter, as shown in the above embodiment and modifications 1 to 3. The management device 12 acquires information about the signal processing components included in the audio device, for example. The management device 12 displays the acquired information about the signal processing components on the GUI. Figure 16 shows the GUI after the specification of the audio device to be connected has been received. In the example in Figure 16, the IDs "9001" and "9002" of two signal processing components and the component names "Processor-64 Hall-A" and "Processor-32 Hall-B" are displayed.

[0052] This synchronization can also be performed at the time of device discovery using the UID. This allows for the pre-acquisition of component information for audio devices discovered by the UID, enabling the display of component information as soon as the audio device is specified, thereby reducing user waiting time.

[0053] Finally, the management device 12 may accept a selection of the synchronization direction. The synchronization direction is either to overwrite the contents stored in the memory of the sound device with those stored in the management device 12, or to overwrite the contents stored in the memory of the management device 12 with those contents of the sound device. However, in the case of overwriting the sound device, it is desirable to do so only if no other management device is connected to that sound device.

[0054] Alternatively, after receiving the selection of the synchronization direction, the management device 12 may display an "Online" button to accept the instruction to start synchronization.

[0055] Figure 17 shows the GUI when the selection of the second protocol (TCP) is accepted. When the management device 12 accepts the selection of the second protocol, it clears the list of audio devices and the first operator, and displays a second operator for specifying the audio device to be connected to using the second protocol. In the example in Figure 17, the management device 12 displays an operator (text input box) for specifying an IP address as the second operator. However, it is preferable for the management device 12 to continue the discovery using the first protocol even when the selection of the second protocol is accepted. This allows the discovery results to be displayed when the user changes the method of discovering audio devices to the first protocol, thereby reducing the user's waiting time.

[0056] UDP discovery using UIDs cannot communicate with acoustic devices outside the subnet. Furthermore, because UDP uses multicast, packet loss may occur. Therefore, users may prefer to use IP addresses instead of UIDs for discovery. Accordingly, the GUI in Modification 4 is configured to allow a series of operations—selecting different protocol-based device discovery, displaying results, and transitioning to online status—all within a single screen without screen transitions.

[0057] When a user selects to search by IP address, sets an IP address, and presses the "Find" button, the system communicates via TCP with the specified IP address's audio device and synchronizes with some of the audio device's parameters. The management device 12 then acquires information about the signal processing components included in the audio device, for example. The management device 12 displays the acquired signal processing component information in a GUI as shown in Figure 16.

[0058] Furthermore, even if discovery by IP address is selected, it is preferable to continue discovery by UID. Also, even if discovery by IP address is selected, it is preferable to continue discovery until the network interface is re-selected. When the network interface is re-selected, the management device 12 starts a TCP discovery for the re-selected network interface. Furthermore, it is preferable that the TCP discovery continues even after the GUI (system settings screen) is closed.

[0059] Note that the above example shows two protocols, the first protocol (UID) and the second protocol (TCP), but the protocols are not limited to this example. For example, the first protocol may use UDP to look up other information such as model name, label, version, IP address, MAC address, subnet mask, and web UI instead of UID.

[0060] The description of this embodiment is illustrative in all respects and not restrictive. The scope of the invention is indicated by the claims, rather than by the embodiments described above. Furthermore, the scope of the invention is intended to include all modifications within the meaning and scope equivalent to the claims. [Explanation of Symbols]
