The digital signals input to the plurality of digital input ports (D inputs) 51 are input to the input patch 52 as they are. The input patch 52 can selectively patch (connect) each of a plurality of input ports, which are input sources of signals, to each input channel of a plurality of input channel sections 53 that are 32 channels. Is supplied with a signal from the input port patched by the input patch 52.

  Each input channel in the input channel unit 53 includes an attenuator, equalizer, compressor (dynamics), fader, pan, send SW unit for turning on / off output to each bus, send level adjusting unit for adjusting the output level to each bus, and the like. In these input channels, frequency balance, level control, and the transmission level to the MIX bus 54 are adjusted.

The data structure of this scene memory is shown in FIG. As shown in this figure, a scene number is assigned to each scene and stored in the scene memory. The number of scenes that can be stored in the scene memory varies depending on the model. For example, when the number of scenes is 100, “scene 1”, “scene 2”, “scene 3”... Stored as “Scene 100”. Then, when the user of the digital mixer 1 designates the scene number and performs a recall operation, the scene data of the designated scene number is read and the parameter set in the current memory is overwritten by the read scene data. The setting state corresponding to the scene is reproduced by the digital mixer 1. This makes it possible to reproduce various scenes from a conference room, banquet hall, mini-theater and multipurpose hall once set.

  Further, FIG. 5B shows the data structure of the current memory. In the current memory, a storage area is secured on the RAM 12, and current data is stored in the current memory.

Although not shown, the output channel section PS is composed of a parameter set for each of the 16 output channels. The configuration of the input channel parameter set will be described by taking the input channel 3PS, which is the input channel parameter set, as an example. The input ch3PS includes Att_PS, which is a parameter set of ATT 60, Eq_PS, which is a parameter set of 4-band PEQ 61, Comp_PS, which is a parameter set of COMP 63, Fader_PS, which is a parameter set of faders and ch on SW 64, and a send adjustment unit 65 for each bus. This is composed of Send_PS, which is a parameter set, and Other_PS, which is another parameter set such as a channel name. As described above, the parameter set of the input channel includes the parameter set of each processing block constituting the input channel, and the parameter set of each input channel other than the input channel 3PS is the same. Furthermore, the parameter set of the output channel is composed of the parameter set of each processing block constituting the output channel.

For example, FIG. 5D shows the data structure of the Comp Scene library, which is a virtual library created by extracting the parameter set for the COMP processing block from the parameter set of each channel of the scene on the scene memory. The Comp Scene library includes Comp_PS, Comp_PS, Comp_PS... That are parameter sets for COMP processing blocks extracted from scenes on the scene memory. The entity of these Comp_PS data exists in the scene memory and does not exist in the Comp Scene library. Then, by specifying one of the Comp_PSs and performing a recall operation, the parameter data of the specified Comp_PS is read out, and the parameter set of the COMP of the selected channel on the current memory is read out by the parameter set read out. Overwriting is performed, and the setting state corresponding to the parameter set is reproduced by COMP of the selected channel.

In the dynamics library screen (part 2) 4, the “Store” button 3 h is disabled, and a “Type filter” box 3 i for displaying a list filtered by the type of dynamics is enabled. When “▼” at the right end in the “Type filter” box 3i is clicked, a dynamics type list 3j shown in FIG. 8B is displayed. In the type list 3j, “Gate” is selected in the case of illustration, and the “Gate” type in the scene number 26 of the parameter set of the COMP 63 of all input channels and all output channels is displayed in the list field 3f. Only the parameter set for which is set is filtered, a list of ch numbers and ch names related to the extracted parameter set is created, and the created list is displayed. In the list column 3f, in the example shown in the figure, the parameter set of “Gate” in the input channel 3 (i03) of the channel name “Vol 3” is selected. As described above, the filter type is specified by the “Type filter” box 3i because the options are enormous for all the channels of each scene. By specifying the type of dynamics, the filter type is appropriately selected. I try to narrow down the options by filtering. If “any” is selected in the “Type filter” box 3i, the parameter set of the COMP 63 for all channels is displayed in a list without filtering.
A rough input / output characteristic of the parameter set of “Gate” of the input channel 3 (i03) of the channel name “Vol 3” selected in the list column 3f is displayed in the second graph column 3e. The input channel 1 (ich01: Vo 1) is displayed in the selected channel column 3a, and the rough input / output characteristics of the “Gate” type parameter set in the input channel 1 are displayed in the first graph column 3b. As before, the channel displayed in the selected channel column 3a becomes the recall destination channel.

Here, the user compares the current characteristic of “Gate” displayed in the first graph column 3b with the input / output characteristic of “Gate” displayed in the second graph column 3e, and compares the COMP 63 of the input ch1. In order to change the input / output characteristic from the current "Gate" input / output characteristic to the input / output characteristic displayed in the second graph column 3e, the "Recall" button 3g is clicked. When the “Recall” button 3g is clicked, the parameter set for controlling the COMP 63 of the input channel 1 displayed in the selected channel column 3a is the channel name “Vo.3” in the scene data of the scene name “foo” of the scene number 26. It is changed to the parameter set of COMP 63 of input ch3 (i03: Vo.1). That is, the parameter set of COMP 63 of input ch 3 in the scene data of scene number 26 in the scene memory is read and overwritten on the parameter set of COMP 63 of input ch 1 in the current memory. At the same time, a rough input / output characteristic of the parameter set of “Gate” recalled to the COMP 63 of the input channel 1 is displayed in the first graph column 3b. The Scene library displayed in the list field 3f is a virtual library, and the Scene library has no parameter set entity, and the parameter set entity is included in the scene data of the scene number.
Note that in the designation of the channel in the designated Scene library, not only the input channel but also the output channel can be designated. Also, in the dynamics library screen (Part 2) 4 when “Scene” is selected, the “Store” button is disabled and does not exist, so it is possible to prevent accidental overwriting of the recalled scene. Can do.

  A flowchart of various processes executed in the digital mixer 1 according to the embodiment of the present invention will be described below. A table of variables used in this flowchart is shown in FIG. In this table, the variable “SCN” is a variable indicating the channel number of the selected channel currently selected as the channel to be edited and displayed in the selected channel column 3a, and the identifier “dynaID” is the dynamics as the type of processing block. The variable “SN (dynaID)” and variable “CN (dynaID)” are variables that indicate the scene number and ch number of the recall source when recalling from a virtual library of dynamics. The variable "DN (dynaID)" is a variable that indicates the data number of the recall source when recalling from the dynamics dedicated library (ie, Comp indiv. Library). The variable "FT (dynaID)" Is a variable indicating the dynamics type specified in the “Type filter” box 3i. As an identifier indicating the type of processing block, in addition to “dynaID”, “eqID” indicating an equalizer (4-band PEQ 61), “sendID” indicating a send adjustment unit (65), and “effID” indicating a built-in effector (57) The variable “SN ()”, the variable “CN ()”, the variable “DN ()”, and the variable “FT ()” are prepared individually for each of these types. In the following, we will focus on only the dynamics processing block and explain the flowcharts of various processes related to the library. Therefore, the variables “SN (dynaID)”, “CN (dynaID)”, and “DN (dynaID)” The “(dynaID)” portion of the variable “FT (dynaID)” is omitted, and simply expressed as a variable “SN”, a variable “CN”, a variable “DN”, and a variable “FT”. In this embodiment, the variable “SN” is used to specify whether the variable “SN” is “Indiv.” Or “Scene” and to specify the scene number when “Scene” is specified. May be replaced with a flag “ISF” indicating “Indiv.” Or “Scene”. Note that the recall destination here is also the store source, and the recall source is also the store destination at the same time.

FIG. 10 shows a flowchart of processing in response to an instruction to open a dynamics library screen executed in the digital mixer 1 according to the embodiment of the present invention. When the user clicks the “Library” button 2a on the dynamics editing screen 2 shown in FIG. 6, processing corresponding to an instruction to open the dynamics library screen shown in FIG. 10 is started, and the library screen is prepared in step S10. Is displayed on the display 16. At this time, the window of the library screen and the frames (frames) of the display elements 3a to 3h in the window are displayed, but the frames are empty and the information is not displayed yet. . Next, the display elements 3a to 3c on the displayed library screen are updated with the display relating to the parameter set of the dynamics (COMP63) of the currently selected channel that is the recall destination in step S11. Here, the channel number of the selected channel currently selected for editing is displayed in the selected channel column 3a, and the type parameter set in the dynamics of the selected channel is displayed in the type column 3c. In the graph column 3b, input / output characteristics based on a plurality of parameters (threshold, etc.) specific to the type set in the dynamics of the selected channel are displayed. Further, the display elements 3d to 3h of the displayed library screen are updated with the display relating to the recall source in step S12. Here, when “indiv.” (“0”: indiv. Library) was set to the variable “SN” when the library screen was closed last time, the displayed library screen is changed to the display mode of FIG. When updated and “Scene” (“1” or more: scene number) is set in the variable “SN”, the displayed library screen is updated to the display mode of FIG. When the process of step S12 ends, the process ends in response to an instruction to open the dynamics library screen.
In the following description, the “library screen” may be either the dynamics library screen (No. 1) 3 or the dynamics library screen (No. 2) 4, but one of them.

Next, FIG. 13 shows a flowchart of the display update process related to the recall source executed in step S12.
When the display update process related to the recall source shown in FIG. 13 is started in step S12, it is determined in step S40 whether "Indiv." Or "Scene" is specified from the variable "SN". If the variable SN is determined to be “0”, “Indiv.” Is designated in the combo box 3d, and the process proceeds to step S41. In step S41, the “Store” button 3h is activated and displayed, the “Type filter” box 3i is deactivated, and the display is omitted. Next, in step S42, based on the parameter set of the Comp indiv. Library prepared in the digital mixer 1, a list of data numbers and names of the parameter set of the library is created, and the created list is displayed in the list field 3f. The parameter set of the data number indicated by the variable “DN” in the list field 3f is selected and displayed as the recall source parameter set.

If it is determined that the variable “SN” is equal to or greater than “1”, “Scene” is specified in the combo box 3d, and the process branches to step S43. In step S43, the “Store” button 3h is disabled and the display is omitted, and the “Type filter” box 3i is enabled and displayed. Next, in step S44, the parameter set of the dynamics (COMP63) of each channel in the scene data of the scene number indicated by the variable “SN” of the scene memory is referred to, and the dynamics type specified in the “Type filter” box 3i. A list of ch numbers and ch names of the extracted parameter set is created, and the created list is displayed in the list column 3f, and the parameter set of the ch number indicated by the variable “CN” in the list column 3f Are displayed as the recall source parameter set.
When the process of step S42 or the process of step S44 ends, the process proceeds to step S45, and the input / output characteristics of the parameter set selected as the recall source are displayed in the second graph column 3e. Here, the parameter set selected as the recall source is the data number indicated by the variable "DN" in the Comp indiv. Library when the variable "SN" is "indiv."("0": indiv. Library) If the variable “SN” is “Scene” (“1” or more: scene number), the ch number indicated by the variable “CN” in the scene data of the scene number indicated by the variable “SN” This is a data set of ch dynamics (COMP63). When the process of step S45 ends, the display update process related to the recall source ends.

Next, FIG. 11 shows a flowchart of processing according to a user operation for changing a variable value related to a recall source executed in the digital mixer 1 according to the embodiment of the present invention. The user operation here is the selection of “Indiv.” / “Scene” or scene number in the combo box 3d on the library screens 3 and 4, and the data number of the parameter set of the Indiv. Library in the list field 3f on the library screen 3. Selection of the scene library channel number in the list field 3f of the library screen 4, selection of the dynamics type in the "Type filter" box 3i of the library screen 4, and the like.
If there is a user operation in which the variable value related to the recall source is changed on the displayed library screen, a process corresponding to the user operation for changing the variable value shown in FIG. 11 is started, and the target variable is determined in step S20. The value is changed according to the user operation. That is, the value of the variable “SN” is changed according to the selection of “Indiv.” / “Scene” or the scene number in the combo box 3d, and the variable is selected according to the selection of the data number in the list field 3f of the library screen 3. Change the value of “DN”, change the value of the variable “CN” according to the channel number selection in the list field 3f of the library screen 4, and the dynamics in the “Type filter” box 3i of the library screen 4 Change the value of variable "FT" according to the type selection. In step S21, the same processing as that in step S12 of FIG. 10 (FIG. 13) described above is performed, and the display of the display elements 3d to 3h on the displayed library screen is updated. When the process of step S21 ends, the process according to the user operation for changing the variable value related to the recall source ends. In the list field 3f of the library screen 4, only the channel numbers in the displayed list are selection targets, and channel numbers that are not displayed cannot be selected.

Next, FIG. 12 shows a flowchart of processing according to the operation of the “Recall” button.
The processing corresponding to the operation of the “Recall” button shown in FIG. 12 is started when the user clicks the “Recall” button 3g on the library screen, and in step S30, the variable SN is changed to “Indiv.” Or “Scene”. Which one is specified is determined. In this case, if “Indiv.” Is specified in the combo box 3d, the scene number is not specified, so the variable “SN” is “0”, and if “Scene” is specified, the scene number is specified. Therefore, the variable “SN” becomes a value of “1” or more. If it is determined that the variable “SN” is “0”, “Indiv.” Is designated in the combo box 3d, and the process proceeds to step S31. In step S31, the parameter set specified by the variable “DN” is read from the Indiv. Library prepared in the digital mixer 1. The variable “DN” is the data number of the parameter set selected as the recall source in the parameter set in the Indiv. Library of the dynamics effect displayed in the list field 3f.

  If it is determined that the variable “SN” is equal to or greater than “1”, “Scene” is specified in the combo box 3d, and the process branches to step S32. In step S32, the parameter set of the dynamics (COMP63) of the ch of the ch number indicated by the variable “CN” in the scene data of the scene number indicated by the variable “SN” is read from the scene memory. When the process of step S31 or the process of step S32 is completed, in step S33, the parameter read by the process of step S31 or step S32 is the dynamics of the ch of the ch number indicated by the variable “SCN” in the current memory (COMP63). Is overwritten by the parameter set. The variable “SCN” indicates the channel number of the selected channel that is currently selected for editing, and the channel number is displayed in the selected channel column 3a. Next, the display of the first graph column 3b is updated in step S34 so that the input / output characteristics of the parameter set after overwriting of the dynamics (COMP63) of the current memory are displayed. When the process of step S34 ends, the process corresponding to the operation of the “Recall” button ends.

Next, FIG. 14 shows a flowchart of processing according to the operation of the Store button.
When the “Store” button 3h is clicked by the user on the dynamics library screen (part 1) 3, the process corresponding to the operation of the Store button shown in FIG. 14 is started, and the variable “SCN” is loaded from the current memory in step S50. The parameter set of the ch dynamics (COMP63) of the ch number indicated by is read. The variable “SCN” indicates the channel number of the selected channel, and the channel number is displayed in the selected channel column 3a. Next, the parameter set read in step S50 is overwritten in step S51 on the parameter set of the data number indicated by the variable “DN” in the Indiv. Library. Next, in accordance with the parameter set read in step S50, the display of the current characteristics of the recall source displayed in the first graph column 3b is updated in step S52. When the process of step S52 is finished, the process according to the operation of the Store button is finished. In the dialog box (not shown) that is temporarily opened between the time when the “Store” button is operated and the processing in step S50 is performed, the user sets the data set to be stored in the Comp Indiv. Library. Can be given any name.

Next, FIG. 15 shows a dynamics library screen (part 3) 5 as another example.
In the dynamics library screen (No. 3) 5 shown in FIG. 15, the list column 3f stops displaying the parameter set list for each scene number, and the list column 5f displays the scene number and the channel number. Can be selected at the same time. In this case, the combo box 5d selects either “Indiv.” Or “Scene”, and the dynamics library screen (part 3) 5 is the dynamics library when “Scene” is selected. It is supposed to be a screen. In the illustrated list field 5f, the input ch1 (26_i01: Vo 1) of the channel name “Vo 1” of the scene number “26” and the input ch 3 (26_i03: Vo 3) of the channel name “Vo 3” of the scene number “26” are shown. ), Input channel 9 (26_i09: MC) of channel name “MC” of scene number “26”, input channel 12 (26_i12: Choir 1) of channel name “Choir 1” of scene number “26”, etc. The input channel 3 (26_i03: Vo 3) is selected and displayed. The ch column 5a to the type column 5c, the second graph column 5e, the “Recall” button 5g, and the “Type filter” box 5h are the ch column 3a to the type column 3c and the second graph column on the dynamics library screen (Part 2). 3e, the “Recall” button 3g, and the “Type filter” box 3i are the same as those in FIG. In the list field 5f of the library screen (No. 3) 5, the user can select one parameter set to be recalled from the parameter sets of the dynamics of the multiple channels of the multiple scenes.
When “Indiv.” Is selected on the dynamics library screen (part 3) 5, the screen is the same as the dynamics library screen (part 1) 3 shown in FIG. However, the “Type filter” box 5h is disabled and the display is omitted, and instead the “Store” button is enabled and displayed.

  The above-described acoustic device according to the embodiment of the present invention is not limited to a digital mixer, and may be a multi-track recorder, a multi-channel effector, a multi-channel amplifier, a speaker processor, or the like. The processing block for opening the Indiv. Library and the Scene library is not limited to the dynamics described above, but may be any of an equalizer and delay in each channel, an effector that can be inserted in each channel, a graphic equalizer, and the like. In any processing block, similarly, a plurality of parameter sets of the same type as the processing block included in each of the plurality of scene data can be listed and shown to the user as one library. In the case of a processing block that can be inserted into each channel, each processing block that is the recall source is not specified by the channel into which the processing block is inserted, but by specifying a serial number that is an identifier for the same type of processing block, and specifying by that serial number It is good to do. Note that the parameter indicating the processing block insertion location is not stored in the Indiv. Library of the processing block, and similarly, the parameter is not stored in the Scene library.

In the embodiment of the present invention described above, the library of the dynamics (COMP63) of the input channel 53 has been described. However, the processing block for preparing the virtual library is not limited to the dynamics. It may be any one processing block such as an equalizer (PEQ 61) for the input channel, a send adjustment unit (65), a dynamics 63 for the output channel, an equalizer 61, and each of the eight effectors. In this case, the filtering condition for each virtual library differs depending on each processing block. In the case of the dynamics of the embodiment, it was a dynamics type (Gate, Duck, Comp, De_Es, etc.), but in the case of an equalizer, the type of the highest band (or lowest band) (shelving or bandpass), send adjustment unit In the case of, filter by the character string ("Vo.", "MC", etc.) included in the channel name given to the input channel, and in the case of the effector, filter by the effect type (reverb, echo, chorus, flanger, etc.) Is preferred.
Further, although filtering of a virtual library is performed under one condition (dynamics type), filtering may be performed under two or more conditions. As the second filtering condition, for example, filtering by a character string included in the name of each channel, filtering by a range of channel numbers, or the like can be considered. In particular, in the example of FIG. 15, since the number of parameter sets displayed in the list field 5f tends to increase, it is desirable that the second filtering can be performed.
