DESCRIPTION JP2005101738
PROBLEM TO BE SOLVED: To perform setting operation of sound image localization for an audio
signal simply and efficiently, and to enable some kind of sensory localization setting. SOLUTION:
In accordance with a start instruction (50, 51) of localization setting from an operator, movement
pattern data for automatically moving a localization point of sound image localization to an audio
signal along a predetermined locus is generated. (52) Based on the generated movement pattern
data, the localization setting value for localization with respect to the audio signal is temporally
varied to output the sound of the localization movement (53). The operator can stop the
movement at an arbitrary localization point (54), and can set the localization setting value at the
time when the movement is stopped as the localization setting value for the audio signal (55).

Sound image localization setting device and program thereof
[0001]
The present invention relates to a sound image localization setting device for setting sound image
localization with respect to an audio signal and a computer program for realizing the control
thereof, and is, for example, an audio mixing device having a function of setting sound image
localization.
[0002]
As is well known, the audio mixing device has a function of setting various parameters for audio
signals for each of a plurality of audio input channels, and one of the representative ones of these
10-05-2019

various parameters is a sound image localization (pan) parameter. is there.
The operation unit (console) of the mixing device conventionally known is provided with a rotary
pan setting operator for adjusting the sound image localization for the audio signal of the
channel for each of a plurality of input channels, and the operator By manually rotating the
operation element corresponding to the target input channel, it is possible to set the localization
for the audio signal in the left and right stereo output channels according to the rotation
operation position.
[0003]
In recent years, with the evolution of the mixing device to cope with the multi-channel surround
sound field control represented by the 5.1 channel surround system, etc. from the sound field
control in the left and right two-channel stereo system, the system size of the mixing device And
the size of the mixing console itself is increasing.
[0004]
As described above, the recent mixing apparatus has a large system size and a large console, so
the operator of the corresponding input channel is searched from the console to adjust the sound
image localization, and the desired localization position is manually searched. Working while
working has been cumbersome for the operator.
In addition, while the functions of the mixing device become more sophisticated and complex,
while controlling other parameters such as volume and sound quality while performing sound
image localization control, it may occur that the operator can not operate it. There was a
problem.
[0005]
In addition, when sound image localization is performed in a multi-channel surround system, for
example, it is necessary to adjust localization in the front-rear direction and the left-right
direction, and there is a problem that the adjustment operation tends to be complicated. Such
localization adjustment in the front / rear and left / right directions often uses multi-dimensional
manipulators such as joysticks, but localization with the joysticks is difficult for the operator to
10-05-2019
2
grasp the setting condition, and it is difficult to obtain good operability. Also, in practice, it is
physically and economically difficult to have multi-dimensional operators for each channel, so
one multi-dimensional operator is used to appropriately select a channel to be processed. After
that, there is almost no need for stereotactic adjustment. The operator must manually perform
the channel selection operation and the localization adjustment operation for each channel in
front of a huge number of input channels, which is the setting operation of sound image
localization in the multi-channel surround system It was inefficient.
[0006]
The present invention has been made in view of the above-mentioned point, and an object of the
present invention is to provide a sound image localization setting apparatus capable of
performing setting operation of sound image localization for an audio signal simply and
efficiently.
[0007]
The sound image localization setting device according to the present invention comprises:
movement pattern data generating means for generating movement pattern data for
automatically moving a localization point of sound image localization with respect to an audio
signal to be processed along a predetermined locus; Localization moving means for temporally
varying the localization setting value for localization with respect to the audio signal based on the
generated movement pattern data, and stopping for stopping movement of the localization point
at an arbitrary position It is characterized in that it comprises: means; and localization
determining means for determining the localization setting value at the time when the movement
is stopped as the localization setting value for the audio signal.
[0008]
According to this, the pattern data generation means generates movement pattern data for
automatically moving the localization point of the sound image localization along the
predetermined locus, and the localization movement means generates the movement pattern data
based on the generated movement pattern data. The localization point of the audio signal is
moved along the predetermined trajectory by temporally changing the localization setting value
for localization with respect to the audio signal.
The movement of the localization point can be stopped at an arbitrary point, and the localization
setting value at the time when the movement is stopped can be determined as the localization
10-05-2019

setting value for the audio signal.
Thereby, the operator observes and listens to the sound where the localization point
automatically moves along the predetermined locus, and if it sounds aurally that the appropriate
localization is obtained, it is set as the sound image localization for the audio signal it can.
Therefore, it is possible to perform the setting of the sound image localization sensuously
without performing the complicated operation of the operator, and it is possible to realize the
simplification and the efficiency improvement of the setting operation of the sound image
localization. Furthermore, since the mechanical sound image localization setting operator can be
omitted, the mixing console can be simplified.
[0009]
An embodiment of the present invention will be described below with reference to the attached
drawings. In the following description, it is assumed that the mixing device according to this
embodiment can cope with sound field control in a multi-channel surround system (for example,
5.1 channel surround system).
[0010]
FIG. 1 is a block diagram showing an example of the hardware configuration of the digital audio
mixing apparatus according to this embodiment. The mixing apparatus generally includes a CPU
1, a memory 2 including a ROM and a RAM, a mixing console 3, a signal processing circuit (DSP)
4, an analog input / output interface (analog I / O) 5, and other devices 6. Are connected via the
communication bus 1B. The CPU 1 executes various programs in the memory 2 to control the
overall operation of the mixing apparatus. As well known, the audio mixing apparatus has a
function of setting various parameters such as volume and sound image localization (pan) for
each channel with respect to audio signals of predetermined plural channels. The mixing console
3 includes various operators for the operator to set various parameters related to mixing, and a
display capable of displaying the setting status of the various parameters. The operator can
execute various instructions and various parameters from the console 3 Allows you to enter
settings etc. The details of the console 3 will be described later.

The analog I / O 5 is an interface that inputs and outputs audio signals, and includes an AD
converter that converts an analog audio signal input to the mixing device from the outside into a
digital signal, and a digital output from the mixing device to the outside It includes a DA
converter that converts the signal into an analog audio signal. The mixing device is provided with
a plurality of predetermined input channels and a plurality of predetermined output channels. An
audio signal is input to the mixing device for each of the plurality of predetermined input
channels via the analog I / O 5, and is appropriately distributed to the plurality of predetermined
output channels and output from the mixing device. Ru.
[0012]
The DSP 4 receives a digital audio signal that has been digitally converted via the analog I / O 5.
The DSP 4 executes the various parameter settings and mixing processing on the digital signal
based on the control signal and parameter setting signal generated by the CPU 1, converts the
result into an analog audio signal via the analog I / O 5, and outputs it. Here, the parameter
setting signal sent from the CPU 1 to the DSP 4 is, for example, a parameter setting signal for
setting sound image localization, and the DSP 4 sets the localization setting value of the input
channel to be processed based on the signal. Then, localization processing is performed on the
audio signal (digital signal) of the channel. Note that the localization processing itself by the DSP
4 is a well-known technology, and a detailed description will be omitted. Localization to an audio
signal is generally realized by controlling the volume difference (power balance) between a
plurality of audio output channels, and the time difference in sound emission (for example, the
sound emission timing between the left and right speakers) .
[0013]
The mixing apparatus according to the present invention, as the sound image localization setting
function executed by the DSP 4, determines the localization of the audio signal along a
predetermined movement locus (pattern) when determining the localization for the audio signal
for each channel. It has a function capable of automatically moving and setting an arbitrary
localization point determined by the operator as having obtained appropriate localization as a
localization setting value for the audio signal. In this specification, the localization setting
function by the automatic movement of the sound image localization is referred to as a "feeling
pan function" in distinction from the sound image localization setting by a normal manual
operation.

[0014]
In this embodiment, an audio signal output from the mixing device is generated from a sound
system (not shown). That is, the operator can operate the mixing apparatus while detecting and
listening to the audio signal (mixing output) subjected to various parameter settings such as
sound image localization and the mixing processing in the DSP 4. In the following description,
the listening environment of the operator is, for example, a multi-channel surround system in
which two-dimensional sound image localization setting should be performed. However, the
present invention is not limited thereto. It may be a system.
[0015]

network interface for connecting to a communication network, and a computer interface for
connecting to another external device such as a personal computer. Control programs etc.
executed by the CPU 1 are not only those stored in the memory 2 such as a ROM but also those
stored in an external storage medium such as a hard disk or a CD-ROM or a communication
network. It is also possible to use what was downloaded via.
[0016]
FIG. 2 is a plan view extracting and showing the main part of the console 3. In FIG. 2, the console
3 roughly includes n channel slits 30 (ch1 to chn) corresponding to a plurality of (n) audio signal
input channels, and a switch group 40 for sound image localization processing according to the
present invention Have.
[0017]
Each channel slit 30 (ch1 to chn) is provided with a fader type operator (FD1 to FDn) 31, a dial
type pan setting operator 32 and a select switch ("SEL1" to "SELn") 33, respectively. It is done.
The operator operates the various operators provided at each channel slit 30 to perform manual
setting of various parameters and the like for the audio signal of the channel.
10-05-2019

[0018]
The fader control 31 is a control for controlling the volume level of the audio signal in the
channel, and is operated to slide vertically. The pan setting operation element 32 is an operation
element for manually adjusting the pan of the left and right stereo with respect to the audio
signal of the channel, and is set and operated so as to rotate in the left and right direction.
[0019]
The select switch 33 is an operating element for selecting a channel to be an execution target of
the "feeling pan function", and is configured by a push button type switch. The operator can turn
on the select switch 33 of the channel (one of ch1 to chn) which is the target of the function
execution to select the target channel. The select switch 33 shown here is an example of a
channel selection means, and the selection means is not limited to this, and any other appropriate
method may be used. For example, when the fader-type controller 31 of each channel is
configured by a fader with a touch sensor, the channel may be selected simply by touching the
fader controller of the target channel. Alternatively, the target channel may be selected on the
display of a GUI capable of centrally managing the setting state of each channel.
[0020]
Further, reference numeral 34 is an example of a joystick (two-dimensional operator) for setting
two-dimensional sound image localization in the front-rear and left-right directions by manual
operation. Only one joystick 34 is provided in the console 3. Selection of a channel to be
subjected to localization setting by the joystick 34 may be configured, for example, on a GUI
display, or the above-mentioned select switch 33 may be used. According to the present
invention, it will be apparent from the following description that setting of two-dimensional
sound image localization can be performed simply, efficiently, and in a sense, in a sense, without
using such a joystick 34. I will.
[0021]
The switch group 40 includes a feeling pan switch 41 (“FEELING PAN”), a feeling pan mode
10-05-2019
7
switch 42 (“F. P (FEELING PAN) MODE”), and a feeling pan start switch 43 (“F. P START” ,
Store switch 44 ("STORE"), and reset switch 45 ("RESET"). In this embodiment, each of the
switches 41 to 44 is composed of a push button type switch.
[0022]
The feeling pan switch 41 is a switch for switching the operation mode of the mixing apparatus
to the "Feeling Pan" function, and the feeling pan function is turned on / off according to the
switch operation of the switch 41 by the operator. The off switches sequentially. FIG. 3 is a
functional block diagram for explaining the outline of the feeling pan function. In FIG. 3, a block
50 represents that the operator instructs to perform localization setting by the feeling pan
function (that is, the feeling pan function is turned on). The operator turns on the feeling pan
function, and then uses the select switch 33 to select and designate a channel for which the
localization is to be adjusted.
[0023]
The feeling pan mode switch 42 (see FIG. 2) is a switch for performing various settings related to
the execution environment of the feeling pan function. Here, various settings related to the
execution environment of the feeling pan function include the selection of the localization
movement pattern, the setting of the movement speed, and the on / off function of temporarily
stopping the movement of the localization at a predetermined singular point in the movement
locus. It is setting etc. Every time the operator presses the feeling pan mode switch 42, the
setting menu is switched in order. The setting contents in these setting menus are displayed, for
example, on a display provided in the console 3 and can be selected and set on the GUI display.
[0024]
A specific example of the localization movement pattern will be described with reference to FIG.
4 (a) shows a horizontal movement pattern, and FIG. 4 (b) shows a vertical (back and forth)
movement pattern. In (a) and (b), a rectangular frame schematically indicates a sound field space
(listening environment), and in the figure, the upper side is the rear of the moving direction of
sound image localization, and the lower side is the moving direction of sound image localization.
Let the front, and the left and right direction in the figure be the left and right direction of the
moving direction of sound image localization. The operator can select an arbitrary pattern from a
10-05-2019
8
plurality of localization movement patterns including those exemplified in FIG. The localization
movement pattern is not limited to two as illustrated, and is arbitrary, for example, a spiral
movement pattern. Basically, it is conceivable to adopt a pattern that scans the sound space (or
sound plane flat) without hesitation, but the invention is not limited to this. Even in the practice
of the present invention, there is no problem. Also, these movement patterns may be made to be
able to use those stored in advance in the memory 2 such as ROM or RAM or other appropriate
storage means, and the operator can use a pointing device such as a mouse. By moving, any
pattern created by detecting and recording the operation, or an input from a tablet (digitizer)
may be used, and these pattern input functions are further provided in the mixing apparatus. It
may be configured to
[0025]
The sound image localization points indicated by white circles on the movement locus shown in
FIGS. 4A and 4B are singular points such as end points on the movement locus on the left, right,
front and back, and a center position. By temporarily stopping the movement of the localization
at such a singular point, the localization point during movement is positioned at the singular
points with respect to the operator who is listening to the sound whose localization is
automatically moved. It can be made to recognize certainly. This is also the case with an ordinary
pan setting operation element 32 or the like, for example, a mark (see FIG. 2) for enhancing the
visibility as a predetermined operation reference position as the center position of left and right
panning Bring about the same effect as the one specified in In addition, as a means to clarify the
said singular point, you may comprise so that the display means lighted when reaching a singular
point may be provided or an alarm sound etc. may be pronounced.
[0026]
The feeling pan start switch 43 is an operation element for starting the movement of the
localization point by the feeling pan function. While the switch 43 is pressed by the operator, the
switch 43 is switched on to execute the automatic movement processing of the localization, and
when the pressing is released (when the operator releases the hand), the switch 43 is switched
off. The movement stop of the localization point is instructed. That is, when the start switch 43 is
pressed in a state where the operation mode of the mixing apparatus enters the "feeling pan"
function (the flow indicated by the arrow 51 in FIG. 3), the CPU 1 follows the predetermined
locus along the localization point. Data for moving (movement pattern data) is generated (block
52 of FIG. 3). The movement pattern data describes data for variably setting the localization
setting value of the DSP 4 so that the localization point can be temporally varied by drawing a
10-05-2019
9
predetermined locus as exemplified in FIGS. 4A and 4B, for example. It is a thing. Note that
generation of movement pattern data can be realized, for example, by referring to a data table,
calculating a predetermined function that changes with time, or the like.
[0027]
The DSP 4 performs localization on the audio signal to be processed based on the localization
setting value. Since the localization setting value is temporally varied based on the generated
movement pattern data, the localization of the audio signal is moved automatically. In the
localization movement, when the switch 43 is turned on, movement is started from the
localization setting value set in the DSP 4 as a start point ("signal processing" of block 53 in FIG.
3). By outputting the sound localized by the “signal processing”, the operator can
automatically listen to the sound whose localization is moved. The operator listens to the sound
moving along the predetermined trajectory, and when it is determined that the optimum
positioning is obtained, turns off the switch 43 to stop the movement in order to determine the
position. That is, generation of movement pattern data is stopped (a flow indicated by an arrow
54 in FIG. 3).
[0028]
The store switch 44 (see FIG. 2) stores the current position of the localization (the current
localization setting value of the DSP 4) moved by the feeling pan function as the localization of
the channel. Here, by “stored”, the localization setting value in the DSP 4 is stored in the
memory 2 such as the RAM as a parameter of the localization reference point of the channel
(hereinafter referred to as “start point data”). That is, the operator uses the store switch 44 to
determine the localization setting value at the time of stopping the movement of localization as
the localization setting for the audio signal of the channel (flow of arrow 55 in FIG. 3). As
described above, according to the feeling pan function, the operator can automatically set the
localization setting value of the channel when the optimum localization is obtained while
listening to the sound of the localization moving automatically. This is convenient for the
localization setting operation while listening to the localization, and can also improve the
localization setting operation efficiency. In addition, the operator can intuitively perform the
localization setting operation.
[0029]
10-05-2019
10
Further, in FIG. 2, the reset switch 45 is an operation for resetting the localization setting value
currently set in the DSP 4 to the setting value stored as the start point data of the channel. This
is, for example, to reset the localization setting value of the DSP 4 to the value stored as the
“start point data” of the channel after the localization is moved by the feeling function, etc.
Use. In each channel, a parameter (starting point data) of any localization reference point is set in
advance as an origin. That is, even if the start point data is not overwritten by the store switch
44, some origin is set and stored in each channel.
[0030]
FIG. 5 is a flow showing a routine of a main program in the mixing apparatus. In the mixing
device, after the power is turned on, the CPU 1 performs “system initialization” processing,
executes “task management processing” for various tasks executed by the mixing device, and
executes tasks according to the input operation by the operator. Get ready ("task switching").
That is, in response to some operator operation performed by the operator in the console 3, the
corresponding processing is executed, and the processing after the “task switching” processing
is repeated thereafter. Here, the “normal PAN process” shown in the drawing is a pan setting
process by manual operation performed using the pan setting operation element 32 or the
joystick 34. The operator turns on the feeling pan switch 41 (see FIG. 2) to enter the feeling pan
process ("FEELING PAN process").
[0031]
FIG. 6 is a flow chart showing an example of the flow of processing in the "FEELING PAN"
processing. The operation processing of the present invention will be described below with
reference to FIG. In addition, although the said flow is divided into two, FIG. 6 (a) and FIG. 6 (b),
for convenience of illustration, these A parts in each of (a), (b) mutually mutually It represents a
series of processing steps to be connected.
[0032]
In step S10, it is determined whether the mixing apparatus is in the feeling pan function based
on whether the "FEELING PAN mode" is off. In the case of YES (that is, when not entering the
FEELING PAN mode), an operation event of the feeling pan switch 41 is detected in step S11.
10-05-2019
11
Here, if the on event of the switch 41 is detected (Yes in step S11), it means that the feeling pan
function is instructed by the operator, and the process proceeds to step S12 to enter the feeling
pan function ( FEELING PAN mode ON). Then, in step S13, the feeling pan operation start flag is
reset (FPSTARTFLG = 0). The feeling pan operation start flag is a flag used to identify the start /
stop of the feeling pan operation according to the two states of “FPSTARTFLG = 1” and
“FPSTARTFLG = 0”. "FP START FLG = 0" represents the stop of the feeling pan operation, and
"FP START FLG = 1" represents the start of the feeling pan operation.
[0033]
On the other hand, in the case of NO in step S10 (that is, when the FEELING PAN mode has
already been entered), an operation event of the feeling pan switch 41 is detected in step S14,
and the operator turns on the switch 41. If not (NO in step S14), the process proceeds to step
S17 to continue the feeling pan process. On the other hand, if there is an on event of the feeling
pan switch 41 in step S5, the process proceeds to step S15 to turn off the feeling pan function.
Then, in step S13, the feeling pan operation start flag is reset. The on / off switching operation
(toggle operation) of the feeling pan function by the feeling pan switch 41 is performed by the
above processing.
[0034]
In step S17, it is determined whether "0" is set in the feeling pan operation start flag.
Immediately after entering the fading pan function, the flag is reset to "0" in step S13, so the
process proceeds to step S18. In step S18, a channel to be set as a sound image localization
setting by the feeling pan function is selected. In this embodiment, the operator performs
channel selection with the select switch 33 (see FIG. 2) provided on the channel strip to be
processed. In step S19, various settings by the feeling pan mode switch 42 (see FIG. 2) are
received. Here, the operator defines implementation conditions for localization movement such
as selection of movement pattern of localization, selection of movement speed, and setting of
temporary stop function on / off at a singular point on movement trajectory.
[0035]
In step S20, it is confirmed that the channel selection operation is completed and the target
channel is determined. In the subsequent processing, the currently selected channel (here, chX) is
10-05-2019
12
treated as a target of localization setting by the feeling pan. In this example, if the target channel
is not selected (NO in step S20), the process returns to step S10, and the process after step S10
can be repeated to wait for the operator to select a channel.
[0036]
If the channel to be processed is selected (YES in step S20), the process proceeds to step S21. In
step S21, an operation event of the store switch 44 is detected, and if there is a switch on event,
the current localization setting value (localization data PANDATAx) of the DSP 4 is stored as start
point data (STARTPOINTx) of the channel in step S22. . In step S23, an operation event of the
reset switch 45 is detected, and if there is a switch on event, the value stored as start point data
(STARTPOINTx) of the channel is sent to the DSP 4 in step S24. Set as PANDATAx). That is, when
the reset switch 45 is turned on, the localization setting value (localization data) at the current
time of the DSP 4 is reset to the value stored as the start point data of the channel chX.
[0037]
In step S25, an operation event of the feeling pan start switch 43 is detected, and if an on-event
is detected, the process branches YES, and the process proceeds to step S26. In step S26, "1" is
set to the feeling pan operation start flag ("FP START FLG = 1"), and the automatic movement of
the localization can be started. On the other hand, if the operation event of the feeling pan start
switch 43 is not detected in step S25 ("NO" in step S25), in this example, the process returns to
step S10 to repeat the processing by the operator. It is possible to wait for the ring pan start
switch 43 to be turned on.
[0038]
After the feeling pan operation start flag is set to "1" in step S26, the process returns to step S17,
and the process branches to NO. That is, it is confirmed that the automatic movement of the
localization can be started by the feeling pan operation start flag "1". In step S27, it is determined
whether the feeling pan start switch 43 is in the on state. As described above, the switch 43 is
turned on while the operator is pressing the switch, and is turned off when the finger is released
from the switch. Therefore, when the switch 43 is on, the operator keeps pressing the switch.
Represents that If feeling pan start switch 43 is on (YES in step S27), the process proceeds to
step S28.
10-05-2019
13
[0039]
In step S28, the CPU 1 generates movement pattern data (FPDATA) corresponding to the
localization movement pattern designated by the operator in step S19, and sends the generated
movement pattern data (FPDATA) to the DSP 4. The DSP 4 sets the received movement pattern
data (FPDATA) as localization data (PANDATAx) of the processing target channel chX at the
current point, and localizes the audio signal of the channel chX with the localization data as a
setting value (panning) Control).
[0040]
In the illustrated flow, after the DSP 4 executes the panning control, the feeling pan process is
returned, and while the feeling pan start switch 43 (see FIG. 3) is kept pressed by the operator,
Steps S10, S14 and S17 are respectively branched to "NO", and the process to step S28 is
repeatedly executed. Meanwhile, movement pattern data (FPDATA) generated in the CPU 1 is
sequentially updated, and localization data (PANDATAx) set in the DSP 4 is varied. The data
update opportunity is defined in accordance with the moving speed designated in step S19. That
is, while the feeling pan start switch 43 is pressed, the update of the localization data
(PANDATAx) is continued, and the localization point represented by the localization data
(PANDATAx) of chX draws the movement locus represented by the movement pattern data and
sequentially It will be transitioned.
[0041]
Further, when the localization movement is set to be temporarily stopped at the singular point of
the localization movement trajectory in the step S19, for example, the localization point
represented by the localization data has reached a singular point such as front / rear left / right
end position or center position. At the point of time, in step S28, the process of stopping the
update of the movement pattern data (FPDATA) for a predetermined time is realized to
temporarily stop the movement of the localization at the singular point.
[0042]
When the operator turns off the feeling pan start switch 43 to turn off the switch 43, the process
10-05-2019
14
branches from step S27 to NO, and the process proceeds to step S29.
In step S29, the presence or absence of the off event of the feeling pan start switch 43 is
detected, and if the switch off event is detected, the process proceeds to step S30. Generation of
movement pattern data (FPDATA) is stopped, and in DSP 4, movement pattern data (FPDATA) at
the present time is set as localization data (PANDATAx) of chX. Then, in step S35, the feeling pan
operation start flag is reset to "0", and the process returns. This suspends the automatic
movement of the localization. When the operator presses the switch 43 again, the localization
movement resumes from the localization data currently set in the DSP 4 as a starting point.
[0043]
By branching to “NO” in step S29 and proceeding to step S31 and later, it is possible to detect
the presence or absence of an operation event of the store switch 44 or the reset switch 45 while
the feeling pan start switch 43 is in the off state. If 44 is turned on (YES in step S31), the current
movement pattern data (FPDATA) is stored as start point data (START POINT x) of the channel
chX (step S32). If the reset switch is turned on (YES in step S33), the localization data currently
set in the DSP 4 (that is, the localization point at the time of stopping the movement) is set as the
start point data of the channel chX (STARTPOINT x Reset)) (step S34). Then, in step S35, the
feeling pan operation start flag is reset to "0" ("FP START FLG = 0").
[0044]
Since the feeling pan operation start flag is reset to "0" in step S35, if the feeling pan function is
turned on, the process returns to step S10 and step S14 after the process up to step S35
described above. Is branched to NO, and since "FP START FLG = 0" in step S17, the process
branches YES, and it is possible to receive a change in the channel to be localized for setting in
step S18. Here, if a channel is newly selected, the same feeling-pan processing as described
above can be performed on the newly selected channel, and localization setting by automatic
movement of localization points can be performed. It should be noted that even if a channel
selection operation is not newly performed in step S18, if any channel (chX in this example) is
selected, it is determined in step S20 that “channel selection is present” and YES Processing
branches in step S21 and step S23, detects presence / absence of operation event of store switch
44 and reset switch 45, overwrites localization data currently set in DSP 4 as start point data,
and resets previous movement stop point Etc.

In the process of repeating step S28, the localization data (PANDATAx) to be sequentially
updated may be sequentially set in the DSP 4 and temporarily recorded as localization data in the
memory 2 such as a RAM. In addition, a function may be further provided so that the localization
data updated in each channel can be stored collectively on all channels. This can be realized, for
example, by configuring the localization data of all channels to be stored by simultaneously
pressing an arbitrary key (such as a shift key) on the console 3 and the store switch 44.
[0046]
In the above example, various settings, instructions, and the like related to the feeling pan
function are performed from the switch group 40 on the console 3. However, various settings
and instructions can be performed with a GUI that can centrally manage the mixing apparatus. It
may be configured as follows. In addition, a personal computer may be connected to the mixing
apparatus so that various settings such as channel selection and instructions can be executed on
the computer side. Furthermore, the feeling pan function according to the present invention may
be provided on the computer.
[0047]
Further, although the example in which the present invention is implemented in the mixing
apparatus is shown in the above-described embodiment, the present invention is not limited to
this and can be applied to an appropriate apparatus conforming to the mixing apparatus. The
present invention can also be configured and implemented as a computer program for
controlling the devices.
