  By the way, in the conventional acoustic signal processing apparatus as described above, the operation for assigning the parameter to the encoder is performed by operating an assignment instruction operator associated with the parameter in advance or assigning from the parameter list. The parameter item was selected.

  However, in the case of using an assignment instruction operator, there is a problem that the number of parameter items that can be assigned to the encoder is limited to the number of the operator. In addition, when using a list, a troublesome operation of selecting from a list is required when assigning parameters, and a quick assignment operation is difficult. Furthermore, the parameters that can be assigned are limited to the range registered in the list. If a large number of parameters are registered in the list in order to increase the choices, it becomes more difficult to quickly select the parameter to be assigned.

Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
First, FIG. 1 shows an embodiment of an acoustic signal processing apparatus having the function of the acoustic control apparatus of the present invention, and a digital mixer (hereinafter simply referred to as “mixer”) which is an embodiment of the acoustic signal processing apparatus of the present invention.

The ROM 12 is a rewritable nonvolatile storage unit such as a flash memory that stores a control program executed by the CPU 11.
The RAM 13 is a storage means for storing data to be temporarily stored and used as a work memory for the CPU 11.

  The communication I / F 14 is an interface for communicating with an external device. The I / F may be connected to a pointing device such as a mouse or a character input device such as a keyboard, or connected to a network so that acoustic signals can be transmitted to and received from other devices. . As the communication I / F 14, an interface of an appropriate standard such as USB (Universal Serial Bus), IEEE (Institute of Electrical and Electronic Engineers) 1394, Ethernet (registered trademark), or the like, depending on the type of external device to be connected. May be provided.

  The operation detection circuit 15 is a circuit for detecting an operation on the operation element 21. The operation element 21 is for receiving an operation on the mixer 10. As will be described later with reference to FIG. 2, the mixer 10 operates on the operation panel 100 with a number of various keys, buttons, and sliders so that the DSP 18 can edit various parameter values used for signal processing. , A rotary encoder, a touch panel laminated on a display 150 by a liquid crystal display (LCD) constituting the display 22, and the like.

  The display control circuit 16 is a circuit for controlling display on the display 22 in accordance with an instruction from the CPU 11. The display 22 is a display means for displaying a GUI (Graphical User Interface), a setting state in the mixer 10, characteristics of an acoustic signal being processed in the mixer 10, and various light emitting diodes (LEDs), It is composed of an LCD or the like.

  The signal input / output unit 17 is an interface for receiving an input of an acoustic signal to be processed by the DSP 18 and outputting the processed acoustic signal. The signal input / output unit 17 is appropriately combined with an analog input terminal having an A / D conversion circuit, an analog output terminal having a D / A conversion circuit, a digital input terminal for digital input / output, and a digital output terminal. There are several.

  The DSP 18 includes a signal processing circuit, and performs mixing, equalizing, etc. on a plurality of signal processing channels (ch) according to the current values of various parameters stored in the current memory for an acoustic signal input from the signal input / output unit 17. Signal processing means for performing various signal processing and outputting the signal to the signal input / output unit 17. It is conceivable that the storage area of the current memory is prepared in a memory provided in the RAM 13 or the DSP 18 itself.

In the mixer 10 having the above configuration, a characteristic point is a function of assigning a parameter for editing a value using the encoder to the encoder of the ch strip provided on the operation panel. Therefore, this point will be described in detail below.
First, FIG. 2 shows a schematic configuration of an operation panel included in the mixer 10. FIG. 2 shows only the components related to the parameter assignment function to the encoder.

  As shown in FIG. 2, the operation panel 100 of the mixer 10 includes a plurality of channel strips 110, encoder selection keys 131 and 132, allocation content indicators 133 and 134, allocation switching keys 135 and 136, a common encoder 140, and a display 150. , A screen selection key group 170 and a layer selection key group 180 are provided.

  Of these, the channel strip 110 is an operator group that is associated with any one of the signal processing channels in the DSP 18 and is a collection of operators for accepting editing operations of parameter values used for the signal processing of the channel. In the example of FIG. 2, 16 channel strips 110 are provided in the input channel section 121, and 8 channel strips 110 are provided in the output channel section 122.

  Then, by operating the keys of the layer selection key group 180, signal processing channels in the DSP 18 can be assigned to these channel strips 110. For example, any of the 1st to 16th, 17th to 32nd, and 33th to 48th layers of 48 input channels is assigned to each of the 16 channel strips 110 of the input channel section 121, and 1 of 24 output channels Any one of the -8th, 9-16th, and 17-24th layers is assigned to each of the eight ch strips 110 of the output channel section 122, and so on. Note that the input channel section 121 and the output channel section 122 can perform layer assignment independently.

Each channel strip 110 includes two channel encoders 111 and 112, a SEL key 113, an ON key 114, and a fader 115.
Of these, the ch encoders 111 and 112 are each an encoder having a knob A as an operation unit as shown in FIG. 3 and capable of two kinds of operations, a rotation operation in the arrow X direction and a pressing operation in the arrow Y direction. . Then, as will be described later, arbitrary channel parameters are independently assigned to the channel encoders 111 and 112, and the channel encoders 111 and 112 are used as operators for setting the parameter value of the allocated channel for the channel corresponding to the channel strip 110. be able to. The reason why the pressing operation is also possible is that the panel can be operated without a sense of incongruity even when a parameter that accepts an on / off setting with a key is assigned.

The SEL key 113 is an operator for accepting selection of a channel corresponding to the channel strip 110. When the SEL key 113 is pressed, the CPU 11 selects a ch corresponding to the ch strip 110 to which the SEL key 113 belongs, and causes the display 150 to display a screen related to the parameter setting of the ch.
The ON key 114 is an operator for accepting the setting of output on / off of ch.
Fader 115 is an encoder that detects the amount of movement of the knob, and is an operator for accepting the setting of the output level of ch.

Next, the encoder selection keys 131 and 132 are keys provided in association with the channel encoders 111 and 112, respectively, and are operators for selecting the corresponding channel encoder as a parameter assignment destination.
The allocation content indicators 133 and 134 are small LCDs provided in association with the channel encoders 111 and 112, respectively, and display for displaying which item parameters are allocated to the corresponding channel encoders. Means.
The assignment switching keys 135 and 136 are operators for switching the assignment contents according to the list when assigning parameters to the ch encoders 111 and 112 using an assignment list described later.

  Further, the common encoder 140 is an encoder provided separately from the ch strip 110, and is configured to be able to perform a rotating operation and a pressing operation, similarly to the ch encoders 111 and 112. As will be described later, regardless of the correspondence between the ch strip 110 and the signal processing ch, an arbitrary parameter of an arbitrary ch can be assigned and used as an operator for setting the value of the parameter. .

  Next, the display 150 is an LCD, and can display various GUI screens according to instructions from the CPU 11. In the example of FIG. 2, as a screen related to the parameter assignment function described here, a GUI screen 160 on which an image of an operator corresponding to a parameter for a signal processing channel selected in response to pressing of the SEL key 113 is arranged. Show.

  The GUI screen 160 is a screen related to the first input channel. Among these screens, for example, an operator 161 indicates an operator for setting a parameter value of a compressor gain. An operation element 162 is an operation element for setting a pan parameter value. The images of the operators 161 and 162 also function as a display unit that displays the current values of the corresponding parameters by the marks 161a and 162a, respectively.

  Then, by touching the part corresponding to the image of any of the controls on the GUI screen 160 while pressing the encoder selection key 131 or 132, the user selects the encoder corresponding to the press of the parameter corresponding to the control. It can be assigned to the channel encoder 111 or 112 of each channel strip 110 corresponding to the key. In this case, the parameter of which signal processing ch is assigned to the ch encoder of which ch strip 110 depends on the correspondence between the ch strip 110 and the signal processing ch determined by the layer as described above.

  In the example of FIG. 2, the gain parameter of the compressor corresponding to the operation element 161 is assigned to the ch encoder 111, and “Cp.Gain” is displayed on the assignment content display 133. Similarly, a pan parameter corresponding to the operator 162 is assigned to the ch encoder 112, and “Pan” is displayed on the assignment content display 134.

  In addition, by touching a portion corresponding to an image of any of the controls on the GUI screen 160 without pressing the encoder selection key, the user assigns a parameter corresponding to the control to the common encoder 140. Can do. In this case, the channel assignment also follows the content of the GUI screen. That is, when the operator 161 is touched in the state of FIG. 2, the compressor gain parameter relating to the first input channel displayed on the GUI screen 160 is assigned to the common encoder 140.

  Note that since there are a wide variety of parameters that can be set in each signal processing channel, it is difficult to arrange an image of an operator corresponding to all parameters in one screen. In view of this, the mixer 10 designs a screen by collecting operators for each related parameter, and allows the user to select which operator is to be displayed on the display 150 with the keys of the screen selection key group 170. ing.

  As can be seen from the above, in the mixer 10, by simply touching the operator image corresponding to the desired parameter on the GUI screen 160 while pressing the encoder selection key 131 or 132, the ch encoder 111 and 112 receive the parameter. Therefore, it is possible to assign a wide range of parameters with a very simple operation.

  However, since this allocation is uniformly performed for all the channel strips 110 to be allocated, the parameters to be allocated are shared by all the signal processing channels corresponding to the channel strips 110 to be allocated. Only parameters are used. For example, when both the input channel section 121 and the output channel section 122 are to be assigned collectively, the send level parameter to the AUX bus that exists in the input channel but does not exist in the output channel is assigned. Excluded from the subject. However, when only the input channel section 121 is to be allocated, a send level parameter to the AUX bus that exists in common for all input channels can be allocated.

Next, processing executed by the CPU 11 in order to realize the parameter assignment to the ch encoders 111 and 112 and the functions associated therewith described above will be described.
First, FIG. 4 shows a flowchart of processing executed by the CPU 11 when there is a touch operation at the position of any of the controls on the GUI screen 160.
When the CPU 11 detects a touch operation to the position of any one of the operators on the GUI screen 160 by the touch sensor stacked on the display 150, the CPU 11 starts the process shown in the flowchart of FIG.

  First, the parameter item corresponding to the touched operator is specified (S11). The parameter item refers to an identifier for identifying a parameter other than the identifier of the signal processing channel to which the parameter belongs. Further, information necessary for this specification can be included in the screen data of the GUI screen 160 being displayed.

  Next, the CPU 11 determines whether any encoder selection key is being pressed at the time of detecting an operation (S12). If the key is being pressed, the process proceeds to step S13 and subsequent steps in order to assign a parameter to the ch encoder corresponding to the key. When a plurality of encoder selection keys are being pressed, only one encoder selection key selected according to some rule, such as first-come-first-served basis, is treated as being effective.

  Then, it is determined whether or not the parameter specified in step S11 is a parameter that exists in common in all the channels corresponding to the channel strip 110 in the allocation range (for example, the input channel section 121 and the output channel section 122) ( S13). As information used for this determination, for each parameter item, information on the range (signal processing ch) where the parameter exists may be stored in the mixer 10 as a table.

If YES in step S13, the CPU 11 next causes the assignment confirmation dialog 210 shown in FIG. 5 to pop up on the display and accepts a user instruction (S14).
This assignment confirmation dialog 210 is a GUI screen for accepting selection of whether or not to assign parameters to the channel encoder according to the user's instruction, and selection of whether the assignment is performed directly or using a list. is there. As options for this, an OK button 211 indicating direct allocation, a cancel button 212 indicating cancellation of allocation, and a list registration button 213 indicating allocation using a list are prepared.

  In step S15, the CPU 11 determines a user instruction depending on which of these buttons is pressed. If the instruction is direct allocation, the channel encoder corresponding to the pressed encoder selection key 131 or 132 of each channel strip 110 in the allocation range is assigned to the channel corresponding to the channel strip 110. The parameter of the item specified in step S11 is assigned (S16). Thereafter, the display of the allocation content display 133 or 134 is updated according to the change of the allocation content (S17), and the process is terminated.

If NO in step S13 or a stop instruction is issued in step S15, the assignment is not performed, and the process is terminated as it is.
If the instruction is assignment using a list in step S15, the CPU 11 next pops up a list registration dialog 220 shown in FIG. 6 on the display and accepts the user's instruction (S18).

  The list registration dialog 220 determines whether or not the parameter item specified in step S11 may be registered in the allocation list for the ch encoder corresponding to the pressed encoder selection key, or whether the parameter item is allocated at the same time as registration. It is a GUI screen for accepting selection. As options for this, an OK button 223 indicating only registration in the list, a cancel button 224 indicating cancellation of registration, and an allocation button 225 indicating that allocation is performed simultaneously with registration are prepared.

Note that the assignment list is a list in which candidates for parameter items to be assigned to the ch encoder in that row are registered in advance for each ch encoder row (unit for assigning one item of parameter). It is displayed on the list display unit 221. A cursor 222 indicates a position where a new parameter item is added to the assignment list.
Then, by operating the assignment switching keys 135 and 136 shown in FIG. 2 while pressing the encoder selection key, the parameter items assigned to the ch encoder can be switched in the normal order or reverse order of the list.

Next, in step S19, the CPU 11 determines a user instruction according to which button of the list registration dialog 220 is pressed. If the instruction only performs registration or performs assignment, first, the parameter item specified in step S11 is additionally registered in the assignment list of the ch encoder corresponding to the pressed encoder selection key (S20). This registration may be performed at the end of the list while leaving the original registration contents.
When the instruction content in the list registration dialog 220 is only registration, the process is finished (S21). In this case, the content of parameter assignment to the ch encoder does not change.

  On the other hand, if the instruction content is also assigned, the process proceeds to step S22. Then, in the assignment list corresponding to the pressed encoder selection key, the parameter item specified in step S11, that is, the item registered in step S20 is selected (S22). Thereafter, the process proceeds to step S16, where the parameter of the selected item is assigned to the ch encoder, and the display of the assigned content indicator is updated according to the change of the assigned content (S17), and the process is terminated.

  With these processes, it is possible to assign parameters to the ch encoder 111 or 112 or register parameter items in the parameter assignment list in response to a touch operation on the GUI screen 160 and a press operation on the encoder selection key 131 or 132. it can.

On the other hand, if the encoder selection key has not been pressed in step S <b> 12, the CPU 11 interprets that the touch operation on the GUI screen 160 is a parameter assignment operation to the common encoder 140. Then, the parameter of the item specified in step S11 of the channel corresponding to the GUI screen 160 being displayed on the display 150, that is, the parameter corresponding to the operator touched on the GUI screen 160 is assigned to the common encoder 140 ( S23). In this case, since it is not necessary to change the display of the allocation content display, the processing is ended as it is.
Through the above processing, it is possible to assign parameters to the common encoder 140 in accordance with a touch operation on the GUI screen 160.

Next, FIG. 7 shows a flowchart of processing when the assignment switching key 135 or 136 is operated.
When the CPU 11 detects the pressing operation of the assignment switching key 135 or 136, the CPU 11 starts the process shown in the flowchart of FIG.

  First, it is determined whether any encoder selection key is being pressed at the time of detecting an operation (S31). If the key is being pressed, the process proceeds to step S32 and subsequent steps in order to update the parameter assignment to the ch encoder corresponding to the key using the assignment list described with reference to FIG. When a plurality of encoder selection keys are being pressed, only one key selected according to some rule, such as first-come-first-served basis, is handled as being valid.

  Then, in the assignment list corresponding to the pressed encoder selection key, the parameter item registered before or next to the currently selected item is selected according to the operation of the assignment switching key 135 or 136. A state is set (S32). Then, the ch encoder corresponding to the pressed encoder selection key 131 or 132 of each ch strip 110 in the allocation range is selected in step S32 for the ch associated with the ch strip 110. Item parameters are assigned (S33). Thereafter, the display of the allocation content indicator 133 or 134 is updated according to the allocation change (S34), and the process is terminated.

On the other hand, if the encoder selection key has not been pressed in step S31, it is determined that no channel encoder has been selected, and the process ends without changing the assignment.
Through the above processing, the parameter assignment contents to the channel encoder 111 or 112 can be updated in accordance with the assignment list in response to a pressing operation on the assignment switching key 135 or 136 and the encoder selection key 131 or 132.

  If such a function is provided, items to be assigned to the channel encoders are registered in the assignment list relatively frequently, so that the type of the GUI screen 160 can be changed or the desired parameter can be handled from the screen. Since parameters can be assigned by a simple operation without searching for an operator, higher operability can be obtained.

Next, FIG. 8 shows a flowchart of processing when one of the ch encoders 111 and 112 and the common encoder 140 is operated.
When the CPU 11 detects the operation of the channel encoders 111 and 112 or the common encoder 140 of any channel strip 110, the CPU 11 starts the process shown in the flowchart of FIG.

  If there is a parameter assignment for the operated encoder (YES in S41), the parameter value assigned to the encoder is changed according to the operation contents of the encoder (rotation count number and pressing / release). (S42), and the process ends. If there is no assignment, a warning to that effect is displayed on the display 150 (S43), and the process is terminated.

  At the time of starting up the mixer 10 or the like, there is a possibility that the assignment has not been made yet. Alternatively, when an operation for canceling the assignment is performed, the state returns to a state in which no assignment is made. In such a state, there is no meaning to operating the encoder, so a warning is given to the user by the above processing to prevent useless operations.

Next, scene saving and recalling operations in the mixer 10 will be described with reference to FIG.
In the mixer 10, in addition to various parameter values used by the DSP 18 for signal processing, at least parameter assignment contents to the channel encoders 111 and 112 are stored in the current memory. In addition, the contents of the assignment list and the assignment contents to the common encoder 140 may be stored.

  When the contents of the current memory are stored (stored) in the scene memory as a scene, these assigned contents are also stored together with the parameter values. When a scene is recalled (recalled), information on the saved assignment contents is also read into the current memory and reflected in parameter assignment to each encoder.

Since it is considered that the parameter assignment content to the encoder is often determined according to the usage scene of the mixer 10, it is saved together with the value of the parameter closely related to the usage scene and can be called again. Assignment according to the use scene is possible without the trouble of assignment operation, and the trouble of operation can be reduced.
Of course, the user may be able to set whether or not to call out the assigned content when the scene is recalled.

This is the end of the description of the embodiment, but it goes without saying that the configuration of the apparatus, the specific processing content, the display content of the screen, the configuration of the operation panel, the operation method, and the like are not limited to those described in the above embodiment. It is.
For example, in the above-described embodiment, the example in which the encoder selection key corresponding to each row of the ch encoder is provided has been described, but one encoder selection key may be provided for a plurality of rows. In this case, before assigning a parameter to a ch encoder or registering a parameter item in the assignment list, which line of the encoders corresponding to the pressed encoder selection key is assigned or registered. The selection may be accepted and assignment or registration may be performed for the selected target.

FIG. 10 shows an example of an encoder selection dialog for this reception.
The encoder selection dialog 230 shown in this figure is provided with an encoder selection button 231 for selecting the channel encoder 111 and an encoder selection button 232 for selecting the channel encoder 112. In the example shown in the figure, a fader 115 which is different in shape from the channel encoders 111 and 112 but is also an encoder can be selected as an assignment destination, and a fader selection button 233 for selecting this is also provided.

Then, after selecting an assignment or registration target with these buttons, the user can confirm the selection by pressing the OK button 234. When the cancel button 235 is pressed, the assignment or registration is canceled.
In the above-described embodiment, the example in which the allocation table described with reference to FIG. 6 is provided for each row of the ch encoder has been described. However, a common allocation table may be provided for a plurality of rows. In this case, parameters of items registered at adjacent positions on the assignment table may be assigned to the ch encoders in the adjacent rows. For example, when the contents of the table are as shown in FIG. 6, when “Aux 5” is assigned to the ch encoder 111, “Pan” is assigned to the ch encoder 112.

In this situation, when the allocation switching key is operated, it is possible to shift the selection items one by one and change the allocation like scrolling in units of rows, or the number of rows using a common allocation table. It is also possible to change the assignment like shifting pages by shifting by minutes.
In addition, the selection of the operation element on the GUI screen 160 may be performed by using a pointing device by clicking the mouse instead of touching the screen.

Further, instead of using the common encoder selection keys 131 and 132 and the assignment switching keys 135 and 136 for all the channel strips 110, for example, the input channel section 121 and the output channel section 122 are separately provided for each channel strip section. An encoder selection key or an assignment switching key may be provided so that parameters can be assigned to the channel encoders independently for each section.
Of course, the shape and number of the ch encoders are not limited to those of the above-described embodiments.

  In addition, each function described in the above embodiment is not limited to the case where the operation is received by the operation element provided in the main body of the mixer 10 and the display is performed by the display device, but also the remote controller such as a physical controller is used. The present invention is also applicable when editing the value of a parameter used by the DSP 18. In this case, for example, the mixer 10 stores programs and data necessary for screen display and parameter setting instructions, and provides the data to the remote controller in response to a request from the remote controller. An operation may be accepted by displaying a screen on the display.

  Furthermore, each of the functions described in the above embodiments is an arbitrary acoustic signal processing means for processing an acoustic signal with a plurality of signal processing channels provided in a synthesizer, a sequencer, a recorder with an editing function, etc. Can be applied to a device that edits a parameter value used for processing an acoustic signal.

Further, the program of the present invention is a program for causing a computer to control required hardware to function as an acoustic control device, and to realize the functions as described above. The program is recorded on a nonvolatile recording medium (memory) such as a CD-ROM or a flexible disk, and the program is read from the memory to the RAM and executed by the CPU. The same effect can be obtained by downloading and executing a device or program from an external device stored in a storage means such as an HDD.
In addition, the configurations and modifications described above can be applied in appropriate combinations within a consistent range.

As is apparent from the above description, according to the acoustic control device, the acoustic signal processing device, and the program of the present invention, the parameters used by the acoustic signal processing means for processing the acoustic signal in the plurality of signal processing channels for the processing of the acoustic signal. When editing the value, the encoder provided in the channel strip can be used more efficiently.
Therefore, the operability of the acoustic control device can be improved by applying the present invention.
