DESCRIPTION JP2008177816
PROBLEM TO BE SOLVED: To specify a signal processing unit to be operated intuitively without
reading a character string on an operation screen. SOLUTION: When an instruction to display an
operation screen of a channel to be operated on a display unit 16 is detected in the controller 2,
it is different from other signal processing units selected by the signal processing unit to which
the channel belongs. A process of drawing an operation screen of a channel to be operated is
performed based on the color palette. As a result, the hue of the operation screen displayed on
the display unit 16 varies according to the signal processing unit to which the channel belongs,
and the operation object is intuitively operated simply by viewing the hue without reading the
character string on the operation screen. It becomes possible to identify the signal processing
unit being considered. [Selected figure] Figure 2
Acoustic signal processing system
[0001]
The present invention relates to an acoustic signal processing system including a plurality of
signal processing units and a control unit that controls the signal processing units.
[0002]
Conventionally, there are known mixers which adjust the levels and frequency characteristics of
audio signals output from a large number of microphones or electric / electronic musical
instruments, mix them, and combine them into several mixing groups and send them to a power
amplifier.

As this mixer, there is known a mixer including a console unit and an engine unit connected to
the console unit via a communication line. In this mixer, in general, a console unit is installed in a
spectator seat away from the stage or a mixer room provided behind the spectator seat, and an
engine unit connected to the console unit is installed in the vicinity of the stage. The operator
who operates the mixer operates the various panel controls provided in the console section to
perform mixing operation while checking the volume and timbre of each audio signal of
instrument sound and singing while confirming the sound heard by the audience. It is adjusted to
the state considered to be most appropriate. The engine unit has a function of processing an
audio signal, includes an input channel of a plurality of microphones / line inputs as an input
signal sequence, programs and mixes the input signal sequence, and outputs a plurality of output
signal sequences. It is outputting to the channel.
[0003]
The signal of each input channel in the input signal sequence is generally amplified by the head
amplifier and output to the mixing processing unit. Then, the frequency characteristic and the
level are adjusted in the mixing processing unit, and mixing is performed in the programmed
combination. The output fader is then set to an arbitrary output level and output to one of the
output channels. As described above, in the mixing system in which the conventional engine unit
and the console unit are connected by the communication path, the engine unit performing the
mixing process can be installed near the stage, and the console unit is installed in the spectator
seat. The mixing operation can be performed while confirming the sound heard by the audience.
In addition, since the microphone / line signal is input to the engine unit to be mixed and
disposed near the stage, the cable can be easily laid and handled. JP 2002-304173 A
[0004]
In the conventional mixing system, one engine unit is connected to the console unit. However, in
an acoustic signal processing system such as a mixing system, a plurality of signal processing
units for performing signal processing of an acoustic signal are connected to a transmission line
It has been proposed that a control unit connected to a transmission path performs control of a
plurality of signal processing units. In such an acoustic signal processing system, even if the
number of channels that can be signal processed by one signal processing unit is limited, a
desired number of channels can be obtained by connecting a plurality of signal processing units
to the transmission path. Signal processing can be performed. Operations such as parameter
10-04-2019

setting of each channel in each signal processing unit are performed by the control unit, but at
that time, an operation screen is displayed on the display unit of the control unit, and parameter
setting of each channel in each signal processing unit on the operation screen And so on. When
performing such an operation, it is necessary to specify the signal processing unit to be operated,
but since the same operation screen is used regardless of which signal processing unit the
current operation target is. By recognizing character string information such as names and
numbers of signal processing units drawn at the upper and lower portions of the screen, the
signal processing unit to be currently operated is specified.
[0005]
However, although it is necessary to read the character string displayed on the operation screen
in order to specify the signal processing unit to be the current operation target, since the
character string is not a prominent display, the operation target can be easily specified. There
was a problem that it was impossible to do. Therefore, an object of the present invention is to
provide an acoustic signal processing system capable of intuitively specifying a signal processing
unit to be operated without reading a character string on the operation screen.
[0006]
In order to achieve the above object, in the audio signal processing system of the present
invention, when the control unit detects an instruction to display the operation screen of the
channel to be operated, the signal processing unit to which the channel belongs is selected. The
main feature is that the process of drawing the operation screen of the channel to be operated is
performed based on a color palette different from that of the other signal processing unit.
[0007]
According to the present invention, when the control unit detects an instruction to display the
operation screen of the channel to be operated, a color pallet different from the other signal
processing units selected by the signal processing unit to which the channel belongs Since the
process of drawing the operation screen of the channel to be operated is performed based on the
above, the hue of the operation screen becomes different according to the signal processing unit
to which the channel belongs, and the character string of the operation screen is read Instead, it
is possible to intuitively identify the signal processing unit to be operated only by looking at the
hue of the operation screen.

be easily upgraded. The DSP 13 is a signal processing unit that processes audio signals of a
plurality of channels as in the case of the extended DSP # 1 and the extended DSP # 2 as
described above.
[0011]
The detection circuit 15 detects an event of the control 14 by scanning the control 14 such as a
panel control, and outputs an event output corresponding to the control 14 having the event. The
controls 14 include a number of controls for operating the equalization characteristics and pan

Thus, packets of control signals and audio signals can be sent from the controller 2 to the
external device 22 through the transmission path 3 and packets of audio signals output from the
external device 22 can be received. Become. The audio signal input circuit 19 takes in an acoustic
signal from the input unit 23 such as a microphone for taking in external sound into the
controller 2, and the audio signal output circuit 20 performs signal processing such as mixing
processing output from the controller 2 The sound signal is output to an output unit 24 such as
an external speaker and emitted. Each of these units is connected to the communication bus 21
to exchange data via the communication bus 21. Further, the extension DSP # 1 and the
extension DSP # 2 do not have any operators or display units in order to have a simple
configuration, and the configuration is based on the operators 14 in the controller 2, the
detection circuit 15, the display unit 16, It is set as the structure except the structure 2-1
enclosed with the broken line which consists of a display circuit 17. FIG. By connecting this
extended DSP to the transmission line 3, it is logically connected to the controller 2 which is the
external device 22 or an extended DSP other than its own through the communication I / F 18
and the transmission line 3.
[0013]
Next, when the controller 2 instructs to draw the operation screen of the channel to be operated,

first channel (Ch1) of the 96 channels belonging to the DSP 13 is to be operated, and the
operation screen shown in FIG. For example, the 25th channel (DSP # 1 Ch 25) of the 48
channels belonging to the above is an operation screen when the operation target is selected. As
apparent from FIGS. 3 and 4, the configurations of the operation screens shown in FIGS. 3 and 4
are the same, but the operation screen when the channel to be operated belongs to the DSP 13
and the extended DSP # The hue on the display unit 16 is made to differ depending on the area
on the operation screen when it belongs to 1. In this case, the hue of the region common to each
operation screen, the region of the knob or button operated by the user, and the region of the
graph displayed is unchanged, and the hue of the portion excluding these regions changes. . As a
result, it is possible to determine which channel the signal processing unit belongs to by simply
looking at the hue of the operation screen of the channel. In addition, the operation screen for
operating any one of the 48 channels belonging to the extended DSP # 2, for example, is the
same as the operation screen shown in FIGS. 3 and 4, and the operation screen in the DSP 13 and
the extended DSP # 1 The operation screen has a hue different from that of the operation screen.

[0014]
As described above, in order to change the hue for each signal processing unit and display the
operation screen on the display unit 16, the user selects a different color palette for each of the
DSP 13, the extended DSP # 1, and the extended DSP # 2. Therefore, FIG. 6 shows the
configuration of the pallet 30 when a user selects a different color pallet for each signal
processing unit. As shown in FIG. 1 to pallet No. The pallet No. 3 consists of three pallets. 1 is for
the controller DSP intended for the DSP 13; No. 2 is for the expansion DSP # 1, and pallet No. 2 is
used. 3 is for the extended DSP # 2.
[0015]
In the operation screens shown in FIGS. 3 and 4, an area a is a common area on the operation
screen for displaying a scene number, and the scene number is, for example, a scene (SCENE)
001. Each scene number is a file name of a scene memory area in which scene data, which is

assumed that the area operated by the user of knobs, faders and buttons in area c to area h is the
area of the graph in areas e and f.
[0017]
The pallet No. in the pallet 30 shown in FIG. 1 to No. An example of the third table is shown in
FIG. The pallet No. shown in FIG. 1 to No. 3 is color number (color No.) It is a table consisting of
columns and actual color columns. Although specific color numbers are designated in the
respective areas a to h of the operation screen, the color numbers designated in the respective
areas a to h are common to the respective pallets. For example, pallet No. 1 to No. In area 3, the
area a is designated as "color No. 1", the area b is designated as "color No. 2", and so on. Pallet
No. In 1, the actual color of "Color No. 0" is "Black", the actual color of "Color No. 1" is "White",
and the actual color of "Color No. 2" is "Gray 1", The actual color of "Color No. 3" is "Gray 2", the
actual color of "Color No. 4" is "Red", the actual color of "Color No. 5" is "Blue", ... It is done.
[0018]
Pallet No. In 2, the actual color of "Color No. 0" is "Black", the actual color of "Color No. 1" is
"White", and the actual color of "Color No. 2" is "Peach 1", The actual color of "Color No. 3" is
"Peach 2", the actual color of "Color No. 4" is "Red", the actual color of "Color No. 5" is "Blue", ... It
is done. Pallet No. In 3, the actual color of "color No. 0" is "black", the actual color of "color No. 1"

"light blue 2", the actual color of "color No. 4" is "red", the actual color of "color No. 5" is "blue", ...
It is done. Thus, pallet No. 1 to No. The same color is assigned to "color No. 0", "color No. 1",
"color No. 4" and "color No. 5" in 3, and these color numbers are made common to each
operation screen. Different palette numbers are specified by specifying the area, the area of the
knob or button operated by the user, and the area where the graph is displayed, and specifying
“color No. 2” and “color No. 3” as the background. Even when a signal processing unit is
operated, the hue of the area in the displayed operation screen remains unchanged, and only the
hue of the background changes.
[0019]
Although FIGS. 3 and 4 show the operation screen of the channel to be operated displayed on the
display unit 16, the operation screen of a plurality of channels may be displayed on the display
10-04-2019
8
unit 16. Therefore, FIG. 5 shows an example in which an operation screen of 7 channels is
displayed on the display unit 16 when an instruction to draw an operation screen of a plurality of
channels is given. In the operation screen shown in FIG. 5, for example, the first channel (Ch1) of
the 96 channels belonging to the DSP 13 is displayed as the channel strip ST1, and the second
channel (Ch2) is displayed as the channel strip ST2. Ch3) is displayed as channel strip ST3. Also,
adjacent to the third channel (Ch3) belonging to the DSP 13, for example, the first channel (DSP
# 1 Ch1) of the 48 channels belonging to the extended DSP # 1 is displayed as a channel strip
ST4, and the second channel (DSP) is displayed. The # 1 Ch2), the third channel (DSP # 1 Ch3),
and the fourth channel (DSP # 1 Ch4) are displayed as channel strips ST5, ST6, and ST7,
respectively.
[0020]
Channel strips ST1 to ST7 indicate areas from the top to the head amplifier adjustment area, the
attenuator adjustment area, the graph area indicating the equalizer frequency characteristic, the
compressor gain characteristic, and a plurality of predetermined frequency levels It consists of a
level meter area, a master level and pan adjustment area, and a channel number display area. In
this case, as shown in FIG. 6, the pallet 30 is a pallet No. for the controller DSP for the DSP 13.
No. 1 and pallet No. for extended DSP # 1. No. 2 and the pallet No. for the extended DSP # 2. 3
and each area of the operation screen has a pallet No. 1 to No. A color number common to 3 is
designated. Then, in the channel strip, the actual color of the color number designated in the
graph display area is made the same even if the pallet number changes, the area being common,
the area of the knob or button operated by the user, It is Thus, the hue of the background of the
channel strip to be displayed is changed according to the signal processing unit to which it
belongs, as shown in FIG. 5 between the channel strip belonging to the DSP 13 and the channel
strip belonging to the extended DSP # 1. However, the hues of the area common to the channel
strips, the areas of the knobs, faders and buttons operated by the user, and the areas of the graph
remain unchanged.
[0021]
Next, FIG. 8 shows a flowchart of pallet selection processing in which the user designates a color
pallet for each signal processing unit. When the user performs an operation of designating a
color pallet in the signal processing unit, this operation is detected in the controller 2 and the
pallet selection processing is started, and the signal processing unit (DSP) to be a target is
selected by the user in step S1. Become so. Next, in step S2, the user selects a pallet number to be
used in the signal processing unit (DSP) targeted in step S1 from pallets consisting of pallets of a
10-04-2019
9
plurality of pallet numbers prepared in advance, and the pallet selection processing ends Do. In
this case, the manufacturer of the controller 2 creates several pallets, and the pallet made up of
pallets of a plurality of pallet numbers prepared in advance is a pallet in which the prepared
pallets are added with pallet numbers. However, it is also possible for the user to create a palette
in advance, attach a palette number to the created palette, and store the palette in storage means
provided in the controller 2. By selecting a pallet for each signal processing unit in this manner, a
pallet 30 as shown in FIGS. 6 and 7 is constructed.
[0022]
Next, when a channel to be operated is selected and drawing of the operation screen is instructed
by the user, the controller 2 detects the instruction and executes the selected channel drawing
process flowchart shown in FIG. Shown in. In this selected channel drawing process, the
operation screen of the channel to be operated is displayed on the display unit 16 as shown in
FIGS. When the channel to be operated is selected, the palette selection process shown in FIG. 8
is executed, and the user designates a color palette for each signal processing unit. When an
instruction to draw the operation screen of the channel to be operated is detected, the selected
channel drawing process is activated, and the hue is not changed by the area of the color palette
information or the operation screen specified for each signal processing unit in step S10. The
drawing setting of whether or not to be read is read. In the drawing setting, the area in which the
hue is invariable can be indicated by a combination of the pallet number and the color number in
the pallet 30. Next, in step S11, a channel selected by the user as an operation target is acquired
as a target channel.
[0023]
Further, in step S12, the color pallet of the pallet number designated by the signal processing
unit to which the channel to be operated belongs is selected, and the color number designated as
the non-changing color is selected in the drawing. In step S13, it is determined whether or not it
is present. Here, when it is determined that the color number to be the non-change color is
designated, the color pallet information of the color number designated as the non-change color
in the color palette selected by branching to step S14 (actually Is reset to the default color palette
information, and the process proceeds to step S15. If it is determined that the color number to be
the non-change color is not specified, the process proceeds to step S15, the operation screen is
drawn based on the color palette, and the display unit 16 is operated The operation screen of the
channel is displayed, and the selected channel drawing process ends.
10-04-2019
10
[0024]
In this selected channel drawing process, when the process of step S14 is performed, the actual
color of the color number designated as the non-change color in the color palette selected in step
S12 is reset to the default hue. . As a result, the hue of the area on the operation screen in which
the color number of the non-change color is specified becomes the default hue and can be
unchanged regardless of the operation target. Therefore, even in the area where the hue changes
in the color palette selected in step S12, the display color of the area can be rendered unchanged
by setting as the non-changeable color. Even when it is determined in step S13 that the nonchange color is not designated, the area common to the color palette selected in step S12, the
area operated by the user, the knob, the fader and the button, and the graph If the actual color
specified in the area is set to the same color as the other color palettes, the area common to the
displayed operation screen, the area of the knob or button operated by the user, and graph
display The hue of the selected area is unchanged.
[0025]
Next, FIG. 10 is a flowchart of a multi-channel drawing process executed by the controller 2 in
which an operation screen as shown in FIG. 5 is displayed on the display unit 16 when an
instruction to display the operation screen of a plurality of channels is detected. Show. In
addition, when the display of the operation screen is instructed, the pallet selection processing
shown in FIG. 8 is executed, and the color pallet is designated in advance for each signal
processing unit by the user. When an instruction to display the operation screen of a plurality of
channels is detected, the drawing setting of presence / absence of changing the hue according to
the area of the color pallet information or the operation screen specified in each signal
processing unit is read in step S20. Be In the drawing setting, the area in which the hue is
invariable can be indicated by a combination of the pallet number and the color number in the
pallet 30. Next, in step S21, it is determined whether all the channels of the plurality of channels
displayed have been drawn. Here, since it is not determined that any channel is drawn yet, it is
determined as No, and the process proceeds to step S22.
[0026]
One of the channels not drawn in step S22 is acquired as a target channel. Next, at step S23, a
color palette of the pallet number designated by the signal processing unit to which the target
10-04-2019
11
channel belongs is selected, and whether or not a color number to be an unchanged color is
designated in the drawing. Is determined in step S24. Here, when it is determined that the color
number to be the non-change color is designated, the color pallet information of the color
number designated as the non-change color in the color palette selected by branching to step
S25 (actually Is reset to the default color palette information, and the process proceeds to step
S26. If it is determined that the color number to be the non-change color is not designated, the
process proceeds to step S26, the operation screen is drawn based on the color pallet, and the
process returns to step S21.
[0027]
Here, it is determined again whether or not all the channels of the plurality of channels to be
displayed have been drawn. In this case, if it is determined that the process of drawing all the
channels is not performed, the processes of steps S22 to S26 are performed again, and the
process of drawing the operation screen for a total of two channels is performed. The processes
of steps S21 to S26 are repeatedly executed until the process of drawing all the channels is
completed. For example, when the operation screen for seven channels is displayed on the
display unit 16 as shown in FIG. 5, the processes of steps S21 to S26 are repeated seven times,
and the seventh process of step S26 is completed. An operation screen as shown in FIG. 5 is
displayed on the display unit 16. Then, it is determined that the process of drawing all the
channels is performed in the eighth process of step S21, and the plural channel drawing process
is ended.
[0028]
In this multi-channel drawing process, when the process of step S25 is performed, the actual
color of the color number designated as the non-change color in the color palette selected in step
S23 is reset to the default hue. . As a result, the hue of the area on the operation screen in which
the color number of the non-change color is specified becomes the default hue and can be made
unchanged regardless of the signal processing unit. Therefore, even in the area where the hue
changes in the color palette selected in step S23, the display color of the area can be rendered
unchanged by rendering and setting it as the non-changeable color. Even when it is determined
in step S24 that the non-change color is not designated, the area common to the color palette
selected in step S23, the area operated by the user, the area of the knob, the fader and the
button, and the graph If the actual color specified in the area is set to the same color as the other
color palettes, the area common to the displayed operation screen, the area of the knob or button
operated by the user, and graph display The hue of the selected area is unchanged.

[0029]
In the present invention described above, when more than two expansion DSPs are connected to
the transmission path 3, the pallet 30 has a color pallet selected by the user for each of the more
than two expansion DSPs. Become. In addition, the hues of the area common to the operation
screen of the operation screen of the channel to be operated, the area of the knob or button
operated by the user, and the area of the graph displayed in the operation screen of the plural
channels are unchanged. The hue of the region may not be invariable, but the hue of at least one
region of the region may be invariant, or the hue of the entire region of the operation screen may
be changed according to the signal processing unit to which it belongs. Instead of preparing the
palette 30, the hue of one or more desired areas on the operation screen may be changed by
performing filtering processing of color information by software.
