  FIG. 1 is a block diagram illustrating a configuration of the mixer 1. The mixer 1 is an example of the sound signal processing device of the present invention. The mixer 1 includes a display 11, an operation unit 12, an audio I / O (Input / Output) 13, a signal processing unit 14, a PC_I / O15, a MIDI_I / O16, other (Other) _I / O17, a CPU 18, a flash memory 19, And a RAM 20.

  The display 11, the operation unit 12, the audio I / O 13, the signal processing unit 14, the PC_I / O 15, the MIDI I / O 16, the other I / O 17, the CPU 18, the flash memory 19, and the RAM 20 are connected to each other via a bus 25. I have. The audio I / O 13 and the signal processing unit 14 are also connected to a waveform bus 27 for transmitting a digital audio signal.

  The audio I / O 13 is an interface for receiving an input of a sound signal to be processed by the signal processing unit 14. The audio I / O 13 is provided with an analog input port or a digital input port for receiving an input of a sound signal. The audio I / O 13 is an interface for outputting a sound signal processed by the signal processing unit 14. The audio I / O 13 is provided with an analog output port or a digital output port for outputting a sound signal.

  The PC_I / O15, the MIDI_I / O16, and the other_I / O17 are interfaces for connecting various external devices and performing input / output. An external PC, for example, is connected to the PC_I / O 15. The MIDI_I / O 16 is connected to a MIDI-compatible device such as a physical controller or an electronic musical instrument. For example, a display is connected to the other_I / O 17. Alternatively, a UI (User Interface) device such as a mouse or a keyboard is connected to the other_I / O 17. Any standard such as Ethernet (registered trademark) or USB (Universal Serial Bus) can be adopted as a standard used for communication with an external device. The connection mode may be wired or wireless.

  The CPU 18 is a control unit that controls the operation of the mixer 1. The CPU 18 performs various operations by reading out a predetermined program stored in the flash memory 19 serving as a storage unit into the RAM 20. The program does not need to be stored in the flash memory 19 of the own device. For example, it may be downloaded from another device such as a server and read out to the RAM 20 each time.

  The display 11 displays various information under the control of the CPU 18. The display 11 is configured by, for example, an LCD or a light emitting diode (LED).

  The operation unit 12 receives an operation on the mixer 1 from a user. The operation unit 12 includes various keys, buttons, a rotary encoder, a slider, and the like. The operation unit 12 may be constituted by a touch panel stacked on the LCD serving as the display 11.

  The signal processing unit 14 includes a plurality of DSPs for performing various kinds of signal processing such as mixing processing or effect processing. The signal processing unit 14 performs an effect process such as mixing or equalizing on the sound signal supplied from the audio I / O 13 via the waveform bus 27. The signal processing unit 14 outputs the digital audio signal after the signal processing to the audio I / O 13 via the waveform bus 27 again.

  FIG. 2 is an equivalent block diagram of the signal processing performed by the signal processing unit 14, the audio I / O 13, and the CPU 18. As shown in FIG. 2, the signal processing is functionally performed by an input patch 301, an input channel 302, a bus 303, an output channel 304, and an output patch 305.

  The input patch 301 receives an audio signal from a plurality of input ports (for example, an analog input port or a digital input port) of the audio I / O 13 and sets one of the plurality of ports to a plurality of channels (for example, 32 channels). To at least one channel. Thus, the audio signal is supplied to each of the input channels 302.

  FIG. 3 is a diagram showing a processing configuration of a certain input channel i. Each of the input channels 302 performs signal processing such as an equalizer (EQ), a gate (GATE), or a compressor (COMP) on the audio signal supplied from the input patch 301 in a signal processing block 351.

  The level of the audio signal after signal processing is adjusted by a fader section (FADER) 352 and then sent to a subsequent bus 303 via a pan section (PAN) 353. The pan unit 353 adjusts the balance of a signal supplied to a stereo bus (a 2-channel bus serving as a master output) of the bus 303.

  Note that the selector causes one of the signal output from the signal processing block 351 and the signal whose level has been adjusted by the fader unit 352 to be input to the subsequent sending unit 355 by a user's selection operation. Can be.

  The audio signal after the signal processing is sent to a subsequent bus 303 after its level is adjusted by a sending unit (SEND) 355 via a selector (SEL) 354. The sending unit 355 can be switched by the user whether to supply a signal to each SEND bus of the bus 303. Further, the sending unit 355 adjusts the level of the signal supplied to each SEND bus according to each send level set by the user.

  The output channel 304 has, for example, 16 channels. In each of the output channels 304, various signal processing is performed on an input audio signal, similarly to the input channel. Each of the output channels 304 sends an audio signal after signal processing to the output patch 305. The output patch 305 assigns each channel to any one of a plurality of analog output ports or digital output ports. Thus, the audio signal that has been subjected to the signal processing is supplied to the audio I / O 13.

  The above signal processing is controlled based on the value of each parameter. The CPU 18 stores the current value (current data) of each parameter in the RAM 20. The CPU 18 updates the current data when the user operates the operation unit 12.

  FIG. 4 is a diagram illustrating a configuration of an operation panel of the mixer 1. As shown in FIG. 4, a touch screen 51, a channel strip 61, a store button 72, a recall button 73, an increase / decrease button 74, and the like are provided on the operation panel of the mixer 1. These components correspond to the display 11 and the operation unit 12 shown in FIG. Although FIG. 4 shows only the touch screen 51, the channel strip 61, the store button 72, the recall button 73, and the increase / decrease button 74, a large number of knobs or switches are actually provided.

  The touch screen 51 is a display unit 11 in which touch panels, which are one mode of the operation unit 12, are stacked, and displays a GUI (graphical user interface) screen for receiving a user operation.

  The channel strip 61 is an area in which a plurality of operators for receiving an operation for one channel are arranged vertically. In this figure, only one fader and one knob are displayed for each channel as operators, but a large number of knobs or switches are actually provided. A plurality (for example, 16) of faders and knobs arranged on the left side of the channel strip 61 correspond to input channels. The two faders and knobs arranged on the right side are controls corresponding to the master output (two-channel bus). In the present embodiment, the operating element is displayed as an image, but may be a physical operating mechanism such as a slider included in the operating section 12, for example.

  The store button 72 is a button for instructing to store a scene. The user can operate the store button 72 to store (store) the current data as one scene data in the flash memory 19. However, the scene data only includes information on the bank to be used, but does not include parameter values. The parameter values are separately stored as library data. The bank and library data will be described later.

  By operating the increase / decrease button 74, the user can select a scene to be saved and recalled from a plurality of scenes. The user operates the recall button 73 to call (recall) necessary scene data, thereby switching scenes.

  FIG. 5 is a diagram illustrating an example of the GUI. The example of FIG. 5 is a GUI (channel viewer) for displaying the processing contents of each input channel to the user and performing adjustment. FIG. 5 shows a channel viewer of the input channel 4 as an example.

  In the channel viewer, a channel name 501, a scene name 502, a characteristic display section 503, an on button 504, a library button 505, a channel performer name 506, an EQ simple characteristic display section 507, a bank name display section 508, a link button 509, a dynamic simple characteristic A display unit 510, a bank name display unit 511, a simple dynamic characteristic display unit 512, and a bank name display unit 513 are displayed. Although only the main components related to the present invention are displayed in the channel viewer of FIG. 5, more buttons and the like are actually displayed.

  In the channel name 501, the name of the input channel is displayed. In this example, the input channel 4 is displayed, and an arbitrary name input by the user (in this example, the cast name of Jullie) is displayed. In the channel actor name 506, the name of the channel and the actor name (Player) are displayed. For example, in a theater or a musical, a large number of casts occur, and there is a performer for each cast. The user can input the cast name (role) in the channel name. Thus, the user can easily grasp which cast the content of the signal processing is currently displayed on the channel viewer.

  The name of the input channel is set on the channel name edit screen shown in FIG. For example, when the user long-presses the channel performer name 506, a channel name edit screen shown in FIG. 6 is displayed. On the channel name editing screen, a “NAME”, “PLAYER”, and “UPDATE / REVERT” column are displayed for each channel. The user can change the cast name by editing the “NAME” column shown in FIG.

  On the channel name editing screen, a predetermined performer can be assigned in the “PLAYER” column. When the user presses and holds each of the performer names in the “PLAYER” section, the screen shifts to the library screen shown in FIG. Alternatively, when the library button 505 shown in FIG. 5 is long-pressed, the screen shifts to the library screen shown in FIG.

  On the library screen, a list of performer names is displayed. In the column on the right side of each performer's name, the name of the channel used in association with the performer's name in the past is displayed. The user selects any one from a list of performer names on the library screen. In the example of FIG. 1 “Andy” is selected.

  When the user presses the “STORE” button, the CPU 18 stores the current signal processing content (current data) as library data in the flash memory 19. The library data includes information indicating the selected channel and parameter values in each signal processing. For example, the user can save and manage the content of the signal processing set in the rehearsal for each performer. Note that the scene data, current data, and library data need not be stored in the flash memory 19 of the own device. For example, it may be downloaded from another device such as a server and read out to the RAM 20 each time.

  If library data has been stored in the past, the user can select the name of the performer and press the “RECALL” button. When the user presses the “RECALL” button, the CPU 18 reads out the library data of the selected performer and overwrites the current performer with the library data. As described above, in the present embodiment, the parameter values are included not in the scene data but in the library data. When the user recalls the library data, the current data is overwritten.

  In theaters or musicals, one performer acts as one cast. Therefore, when the mixer 1 is used for a play or a musical, it is preferable to save and manage the contents of the signal processing of each channel for each actor, not for each scene. However, in the present embodiment, scene data includes information of a bank to be used. Therefore, when scene data is recalled, the bank to be used is switched, and the content of signal processing is switched.

  In a theater or a musical, etc., different actors (substitutes) may play the same cast. Different actors often change the content of the signal processing. In addition, even in the same performer, the tone of the voice is different depending on the day, the microphones of different channels are used, and various situations are different. Therefore, the content of the signal processing may be changed.

  Therefore, in the mixer 1 of the present embodiment, the content of the signal processing can be stored and managed for each performer, each date, or each substitute in the library screen.

  Returning to FIG. 6, the performer selected for each channel is displayed on the channel name edit screen. An “UPDATE” button and a “REVERT” button are displayed on the channel selected by the performer. The "UPDATE" button and the "REVERT" button are not displayed for channels for which no performer has been selected.

  When the user presses the "UPDATE" button, the name of the channel (casting name) is saved, and the name of the associated actor is saved. These pieces of information are stored in the flash memory 19. When the user presses the “REVERT” button, the state returns to the state immediately before. For example, if another performer was selected immediately before, the state returns to the state of the other performer.

  Returning to FIG. 5, in the center of the channel viewer, a characteristic display unit 503, an ON button 504, an EQ simple characteristic display unit 507, a bank name display unit 508, a link button 509, a dynamic simple characteristic display unit 510, and a bank name display unit 511 , A dynamic simple characteristic display unit 512 and a bank name display unit 513 are displayed. In other words, the central part of the channel viewer is a display column related to the processing of EQ and dynamics.

  The characteristic display unit 503 displays the frequency characteristics of an equalizer that processes the sound signal of the current channel (CH.4 in this example). Each time the user presses the ON button 504, the user can switch on / off the EQ and dynamics. When the on button 504 is turned on, the equalizer, dynamics 1 (here, GATE), and dynamics 2 (here, COMP) processes are performed on the sound signal of the channel. When the on button 504 is turned off, the processing of the equalizer, dynamics 1 (here, GATE), and dynamics 2 (here, COMP) is canceled for the sound signal of the channel (the sound signal is passed through). However, the ON button 504 may be provided only for the equalizer or individually for each process. Further, the equalizer and the attenuator (ATT) may be linked with the ON / OFF of the ON button 504.

  Below the characteristic display section 503, an EQ simple characteristic display section 507, a bank name display section 508, and a link button 509 are displayed as EQ columns.

  The user designates any one bank by pressing each bank button of the bank name display section 508. Each bank is associated with an equalizer characteristic. When the user performs a designation operation for designating any one bank, the characteristic is switched to an equalizer characteristic corresponding to the designated bank.

  As described above, the CPU 18 and the DSP 14 perform signal processing based on the parameter values in the current data. In the RAM 20 of the present embodiment, current data for each bank is stored as a plurality of parameter sets. The CPU 18 and the DSP 14 perform signal processing based on the specified parameter set (current data of the specified bank) when an operation of specifying a parameter set to be used is performed.

  Note that the current data for each bank may be stored in the flash memory 19. In this case, when a bank designation operation is performed, the CPU 18 reads the current data of the designated bank from the flash memory 19 and overwrites the current data of the RAM 20. However, if the current data for each bank has been expanded in the RAM 20 in advance, the CPU 18 only needs to change the current data to be used among the expanded current data. In this case, the CPU 18 can change the content of the signal processing much faster than reading the current data from the flash memory 19 each time, and the load associated with the change in the signal processing is reduced.

  Similarly, a simple dynamics characteristic display unit 510 and a bank name display unit 511 are displayed in the dynamics 1 column, and a simple dynamics characteristic display unit 512 and a bank name display unit 513 are also displayed in the dynamics 2 column. .

  The user can change the contents of the dynamics 1 by pressing the bank button of the bank name display section 511 and designating any one bank. In addition, the user can change the content of Dynamics 2 by pressing the bank button of the bank name display portion 513 and designating any one bank.

  Note that a link button 509 is displayed between the EQ column and the dynamics column. When the user turns on the link button 509, the bank in the EQ column and the bank in the dynamics column are linked. That is, when the link button 509 is turned on, the banks of the EQ, Dynamics 1 and Dynamics 2 are all switched to the same bank. For example, when the bank A is specified in the bank name display unit 508, the bank A is also specified for the banks of the dynamics 1 and the dynamics 2.

  On the simple EQ characteristic display unit 507, the simple dynamic characteristic display unit 510, and the simple dynamic characteristic display unit 512, images indicating simple characteristics are displayed corresponding to the respective banks. For example, a frequency characteristic is displayed on the EQ simple characteristic display unit 507. In the simplified dynamic characteristic display section 510 and the simplified dynamic characteristic display section 512, the level relationship between input and output is displayed. Therefore, when changing the bank, the user can easily determine what kind of signal processing to switch to.

  As described above, the user can change the content of the signal processing by performing the bank designation operation. The operation of designating the bank may be performed each time by the user, but the bank can be designated also as an instruction to read out the scene data. As described above, the scene data includes information indicating a bank to be used (information indicating a parameter set corresponding to each scene). Therefore, when receiving the instruction to read the scene data, the CPU 18 and the DSP 14 switch the current data of the bank to be used based on the scene data and change the content of the signal processing.

  FIG. 8 is a conceptual diagram showing the relationship among scene change, parameter change, bank switching, and signal processing. In the example of FIG. 8, the bank A is associated with the scene data of the scene 1, the scene 2, and the scene 6. Bank B is associated with the scene data of scene 3 and scene 4. The bank C is associated with the scene data of the scene 5.

  In a theater or musical, the content of signal processing may be changed even for the same cast and the same performer. For example, there are cases where the sound field environment changes between rehearsal and production, and the characteristics of the equalizer are adjusted. Further, even when the scene changes, the content of the signal processing may be changed. For example, when the costume changes depending on the scene and the arrangement of the microphones changes, it is necessary to change the content of the signal processing. Also, when the scene changes, the same costume may be returned again. In the mixer 1 of the present embodiment, by switching the bank to be used for each costume, even the same cast and the same performer can change the content of the signal processing.

  In the example of FIG. 8, first, when the user recalls scene data of scene 1, signal processing is performed using the current data of bank A. Here, signal processing is performed using the value of the EQ parameter A as the current data of the bank A.

  Next, the user adjusts the characteristics of the equalizer in scene 2. When the user adjusts the EQ parameters, the current data changes. In this example, in the scene 2, the user adjusts the EQ parameter A to the EQ parameter A '. Therefore, at this point, the current data of bank A is updated.

  Next, when the user recalls scene data of scene 3, signal processing is performed using the current data of bank B. That is, in the scene 3, signal processing is performed using the EQ parameter B. In the scene 4, the user has adjusted the EQ parameter B to the EQ parameter B '. Therefore, in scene 5, the current data of bank B is updated.

  Next, when the user recalls scene data of scene 5, signal processing is performed using the current data of bank C. Here, signal processing is performed using the EQ parameter C.

  Then, when the user recalls the scene data of the scene 6, the signal processing is performed on the current data of the bank A. The current data of the bank A has been updated to the EQ parameter A 'in the scene 2. Therefore, when the scene data of scene 6 is recalled, signal processing is performed using the value of the parameter of the EQ parameter A '.

  In the present embodiment, the parameter values are stored as library data, and the scene data includes only the information of the bank to be used, but does not include the parameter values. Therefore, even if the scene is changed, the current data is maintained. Therefore, even when the scene changes and the performer's costume returns to the original costume, the contents of the adjusted signal processing can be continuously used.

  If the user wants to save the adjusted parameter values, the user presses the STORE button on the library screen shown in FIG. 7 and overwrites the library data with the current data or sets the current data as new library data. Enter the name of the performer and press the STORE button. If the user wants to reproduce the state before adjustment (return to the original state), the user presses the RECALL button on the library screen shown in FIG.

  FIG. 9 is a diagram illustrating an example of a screen for adjusting the content of signal processing. FIG. 9 shows an EQ editing viewer as an example. For example, when the user long-presses the characteristic display section 503 in FIG. 5, the EQ editing viewer shown in FIG. 9 is displayed.

  The EQ editing viewer displays an EQ characteristic screen 701, a bank name display section 702, a switch button 703, and a group of operators 704. When the user presses the switch button 703, the screen shifts to the corresponding EQ editing viewer, dynamics editing viewer, or other signal processing editing screen.

  The user can adjust the content of the signal processing by operating the operator group 704 while checking the EQ characteristics on the EQ characteristics screen 701. On the EQ characteristic screen 701, a bank name display section 702 is displayed. Therefore, the user can easily grasp which bank is currently adjusting the signal processing.

  The bank name can be freely edited by the user. For example, when the user long-presses the bank name display sections 508, 511, and 513 in FIG. 5, the screen shifts to a bank name editing screen (not shown). When the bank name display section 702 on the EQ characteristic screen 701 is long-pressed, the screen may shift to the bank name editing screen. When the user inputs a bank name on the bank name editing screen, the display of the bank name display sections 508, 511, 513, and 702 is changed.

  For example, as shown in FIG. 10, the description of the banks A, B, C, and D in the bank name display sections 508, 511, and 513 is “Main”, “Hatt1”, “Hatt2”, and “Special”, respectively. Is changed to Thereby, the user can easily grasp the purpose of each bank (for example, a costume name).

  The EQ editing viewer may display the value of ATT and display a screen for adjusting the value of ATT as shown in FIG. When the ATT and the equalizer are linked, when the user changes the bank, the value of the ATT changes with the change of the EQ characteristic.

  In the example of FIG. 14, the vertical center position of the EQ characteristic screen 701 changes in conjunction with the ATT value. In the example of FIG. 14, the value of ATT is −15 dB. Therefore, the vertical center position of the EQ characteristic screen 701 is −15 dB. Alternatively, as shown in FIG. 9, the center position in the vertical direction may be 0 dB. In this case, the EQ characteristics displayed on the EQ characteristics screen 701 may move up and down in conjunction with the value of ATT.

  9 and 14, the content of the signal processing may be adjusted by the user touching the EQ characteristic on the EQ characteristic screen 701. For example, when the user swipes the EQ characteristic of the EQ characteristic screen 701 upward by -5 dB, the value of ATT changes to -10 dB.

  FIG. 11 is a flowchart showing the operation of the mixer 1. As shown in FIG. 11, the CPU 18 first develops the current data of each bank in the RAM 20 (S11). This processing corresponds to storing a plurality of parameter sets in the storage unit (RAM) in the present invention.

  The current data is transferred to the flash memory 19 when the power is turned off. When the power is turned on, the current data developed in the RAM 20 immediately before the power is turned off is restored. When the recall button is pressed on the library screen in FIG. 7, the library data is overwritten on the current data.

  When the CPU 18 receives the operation for changing the parameter value (YES in S12), the CPU 18 updates the current data of the current bank (S13). If there is no operation for changing the parameter value, the process of S13 is not performed. This processing is performed in accordance with the present invention by receiving a change operation of a parameter value included in a parameter set, and when the change operation is received, the currently used one of a plurality of parameter sets stored in a storage unit (RAM). And updating the parameter set.

  When accepting the bank designation operation (S14: YES), the CPU 18 switches to the current data of the designated bank and changes the content of the signal processing (S15). This processing corresponds to accepting a designation operation for designating a parameter set to be used among a plurality of parameter sets according to the present invention, and performing sound signal processing based on the parameter set designated by the designation operation. .

  FIG. 12 is a flowchart showing the operation of the mixer 1 when reading scene data. When receiving the instruction to read the scene data (YES in S21), the CPU 18 switches to the current data of the bank corresponding to the read scene data and changes the content of the signal processing (S22).

  FIG. 13 is a flowchart showing the operation of the mixer 1 when the link function is valid. The same processes as those in FIG. 11 are denoted by the same reference numerals, and description thereof will be omitted. When accepting a bank designation operation (S14: YES), the CPU 18 determines whether or not the link button 509 is turned on (S101). If the link button 509 is off (S101: NO), the current data of the designated bank is switched to change the content of the signal processing (S15).

  On the other hand, if the link button 509 is on (S101: YES), the CPU 18 switches to the designated bank for all effects to be linked and changes the content of the signal processing (S102). For example, when the bank A is designated in any of the EQ, dynamics 1 and dynamics 2 in FIG. 5, the bank A is designated in all of the EQ, dynamics 1 and dynamics 2.

  The description of the present embodiment is illustrative in all aspects and should not be construed as limiting. The scope of the present invention is defined by the terms of the claims, rather than the embodiments described above. Further, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the claims.

  For example, in the present embodiment, a button for accepting bank designation is displayed on the touch screen 51. However, for example, bank designation may be received by any hardware button on the console. In the touch screen 51, an example is shown in which the currently designated bank is displayed in reverse video, but it is sufficient that the bank is displayed in a display mode different from that of the other banks. For example, an LED may be installed on each hardware button on the console, the LED of the currently designated bank may be turned on, and the LED of another bank may be turned off.
