Hereinafter, embodiments of the present invention will be described in detail with reference to
the drawings. In the following description, the parts denoted by the same reference numerals
have substantially the same functions. Further, in order to clarify the invention, the description of
the overlapping portions is appropriately omitted.
[0015]
Embodiment 1 [1-1: Configuration] FIG. 1 is a block diagram showing a configuration of a voice
adjustment device according to Embodiment 1. As shown in FIG. The audio adjustment device
according to the first embodiment includes an audio signal input unit 10, an operation unit 11, a
level adjustment processing unit 12, an audio signal output unit 13, a level detection unit 14, and
a target level setting unit 15. The relative value calculation unit 16 and the fader control unit 17
are provided.
[0016]
The audio signal input unit 10 inputs an audio signal from the outside of the device. For example,
the audio signal input unit 10 is an input terminal installed in the audio adjustment device, and is
connected to an audio line. The audio signal input unit 10 inputs an audio signal output from a
11-04-2019
5
microphone connected to an audio line destination or an audio reproduction device. The audio
signal input by the audio signal input unit 10 is sent to the subsequent level adjustment
processing unit 12.
[0017]
The operation unit 11 receives an adjustment operation on the sound level from the operator. In
the operation unit 11, a slide-type fader 11a is installed as an operator for each channel. By
manually moving the faders 11 a along the slide axis, the corresponding operation signal is
output to the level adjustment processing unit 12. The amplification factor in the adjustment
processing of the sound level changes based on the operation signal. Also, the faders 11 a of each
channel are respectively connected to the motor 11 b, and slide automatically under the control
of the fader control unit 17.
[0018]
A reference position mark 11c indicating the reference position of the fader is disposed near
each fader 11a. In the first embodiment, the reference position mark 11c is a line disposed near
the center of the slide movable range of the fader 11a. When the fader 11a is operated to match
the line position, the audio level of the audio signal after the level adjustment processing matches
the target level which is the target value.
[0019]
The level adjustment processing unit 12 performs level adjustment processing for amplifying or
attenuating the audio level of the audio signal input by the audio signal input unit 10 based on
the adjustment operation received by the operation unit 11. The audio signal subjected to the
level adjustment processing in the level adjustment processing unit 12 is sent to the audio signal
output unit 13 and the level detection unit 14.
[0020]
The audio signal output unit 13 outputs the audio signal after the level adjustment processing in
11-04-2019
6
the level adjustment processing unit 12 to the outside of the apparatus. For example, the audio
signal output unit 13 is an output terminal installed in the audio adjustment device, and is
connected to an audio line. The audio signal output unit 13 outputs an audio signal after level
adjustment processing to a speaker or the like connected to an audio line destination.
[0021]
The level detection unit 14 detects the audio level of the audio signal after the level adjustment
processing, and outputs the value of the detected audio level to the subsequent relative value
calculation unit 16.
[0022]
Specifically, the level detection unit 14 has a filter unit 14 a and an averaging processing unit 14
b.
The filter unit 14a performs a filtering process in which an audio signal whose audio level is
equal to or less than a predetermined threshold value is discarded. The averaging processing unit
14 b calculates an average value of the audio level of the audio signal after the filtering process
for each predetermined period. The average value of the audio levels calculated by the averaging
processor 14 b is output to the relative value calculator 16 as the value of the audio level
detected by the level detector 14.
[0023]
The target level setting unit 15 sets a target level that is a target value of the audio level of the
audio signal after the level adjustment process. The target level setting unit 15 sets a target level
for each channel.
[0024]
The relative value calculation unit 16 calculates a relative value between the value of the sound
level detected by the level detection unit 14 and the value of the target level set by the target
level setting unit 15. For example, the relative value calculation unit 16 obtains the relative value
11-04-2019
7
by obtaining the difference between the value of the detected sound level and the value of the set
target level. Further, as another calculation method, the relative value calculation unit 16 may
obtain the relative value by dividing the value of the target level by the value of the detected
sound level. The relative value calculating unit 16 sends the calculated relative value to the fader
control unit 17.
[0025]
The fader control unit 17 performs control of presenting the adjustment operation amount in the
fader 11a corresponding to the relative value calculated by the relative value calculation unit 16
to the operator using the fader 11a itself.
[0026]
More specifically, the fader control unit 17 drives the motor 11b so that the fader 11a moves to
a position offset from the reference position of the fader 11a by the adjustment operation
amount corresponding to the calculated relative value. Take control.
Since the fader 11a is a sliding type fader, the fader control unit 17 controls the motor 11b to
move to a position away from the reference position by a distance corresponding to the relative
value.
[0027]
[1-2: Operation] FIG. 2 is a flowchart showing the flow of the operation of the voice adjustment
device according to the first embodiment.
[0028]
The target level setting unit 15 sets the target level of the audio signal after the level adjustment
process (step S101).
The target level setting unit 15 resets the target level when it is necessary to change the target
level, such as a scene switching timing. For example, the target level setting unit 15 periodically
monitors a table in which each scene and time and the corresponding target level are combined,
11-04-2019
8
and when it is necessary to change the target level, the target level is reset.
[0029]
When the audio signal input unit 10 inputs an audio signal from the outside of the device, the
level adjustment processing unit 12 performs level adjustment processing based on the
adjustment operation performed by the operation unit 11 on the input audio signal (step S102).
). The audio signal after the level adjustment processing is output to the outside from the audio
signal output unit 13 and sent to the level detection unit 14.
[0030]
The level detection unit 14 detects an audio level in the audio signal after the level adjustment
processing, and sends the value of the detected audio level to the relative value calculation unit
16 (step S103). The relative value calculation unit 16 reads the value of the target level set in
step S101, calculates the relative value to the value of the audio level detected by the level
detection unit 14, and sends it to the fader control unit 17 (step S104) .
[0031]
The fader control unit 17 performs control of presenting the adjustment operation amount in the
fader 11a corresponding to the calculated relative value to the operator using the fader 11a itself
(step S105). Specifically, the fader control unit 17 moves the motor 11b so that the fader 11a
moves from the reference position of the fader 11a indicated by the reference position mark 11c
to a position offset by the adjustment operation amount corresponding to the relative value.
Control to drive the
[0032]
As described above, the fader control unit 17 performs control to change the physical position of
the fader 11a by driving the motor 11b connected to the fader 11a. The fader control unit 17
indicates the relative value between the target level set in advance and the audio level of the
audio signal after the level adjustment processing based on the physical position of the fader
11-04-2019
9
11a. Therefore, in the audio adjustment device according to the first embodiment, the fader 11a
itself as the main operation target functions as an audio level indicator.
[0033]
When the position of the fader 11 a is automatically moved based on the control performed by
the fader control unit 17, the operation signal is not output to the level adjustment processing
unit 12. That is, even if the position of the fader 11a is changed based on the control performed
by the fader control unit 17, the amplification factor in the level adjustment processing
performed by the level adjustment processing unit 12 does not change.
[0034]
When the fader 11a is manually adjusted, an operation signal is output to the level adjustment
processing unit 12, and level adjustment processing is performed with an amplification factor
corresponding to the amount of adjustment operation. In addition, the operation signal generated
at the time of the manual adjustment operation is output to the fader control unit 17 in addition
to the level adjustment processing unit 12 so as to prevent a gap between the automatic control
performed by the fader control unit 17 and the automatic control. When the fader control unit
17 receives an operation signal output based on the manual adjustment operation on the fader
11a, the fader control unit 17 performs offset setting to achieve consistency with automatic
control.
[0035]
FIG. 3 shows an example of the state of the operation unit 11. The difference between the current
position of the fader 11a and the reference position of the fader 11a indicated by the reference
position mark 11c represents the amount of adjustment operation required to achieve the target
level.
[0036]
In FIG. 3, the positions of the faders 11a in the channel 1 and the channels 3 to 5 respectively
11-04-2019
10
coincide with the positions of the reference position marks 11c. Therefore, the audio levels of
channels 1, 3 to 5 match the target levels set for each channel. On the other hand, in the channel
2, the position of the fader 11a is located behind (below) the reference position mark 11b.
Therefore, the audio level after the level adjustment process in channel 2 has not reached the
target level.
[0037]
A case where time passes from the state of FIG. 3 and the target level is changed or the detected
sound level is changed will be described. FIG. 4 shows the state of the operation unit 11 when
time passes from the state of FIG.
[0038]
Compared with the state of FIG. 3, in the state of FIG. 4, the fader 11a of the channel 4 is located
forward (upward) and the fader 11a of the channel 5 is located backward (downward). When no
manual operation is performed on the fader 11a, it indicates that the sound level detected for the
audio signal of the channel 4 has risen significantly or the target level set for the channel 4 has
fallen significantly. It also indicates that the audio level detected for the audio signal of channel 5
is slightly lowered, or the target level set for channel 5 is slightly raised.
[0039]
The fader control unit 17 moves the fader 11a to a position offset from the reference position of
the fader 11a by the distance corresponding to the newly calculated relative value based on the
detected audio level or the change of the target level. Control the motor 11b of the channels 4
and 5.
[0040]
[1-3: Effect] According to the audio adjustment device according to the first embodiment, the
position of the fader 11a, which is an operation element for performing the audio level
adjustment operation, indicates the offset with the target level as the reference value as it is. ing.
11-04-2019
11
Therefore, the operator can easily realize the target level by performing the adjustment operation
for the adjustment operation amount presented based on the control performed by the fader
control unit 17. Therefore, the voice adjustment operation becomes easy, and the burden on the
operator can be reduced and the erroneous operation can be prevented.
[0041]
Since the filter unit 14a performs the above-described filtering process on the audio signal after
the level adjustment process, it is possible to prevent the position of the fader 11a from being
unnecessarily changed by the ambient noise or the input level at the time of silence.
[0042]
The averaging processing unit 14b performs averaging processing on the sound level to obtain
an average sound level in a predetermined period, thereby preventing frequent operation of the
fader that hinders the operation and improving the visibility.
[0043]
By setting the target level individually for each channel, the target level setting unit 15 can
perform weighting in accordance with the importance of the channel.
[0044]
In the above description, although the case where the vicinity of the center of the stroke movable
range of the fader 11a is set as the reference position has been described, the present invention
is not limited to this.
It is possible to set the reference position of the fader 11a by arranging the reference position
mark 11c at any position in the movable range of the fader 11a.
[0045]
Also, an audio level scale may be arranged along the slide axis of the fader 11a, and the zero
point of the scale may be set as the reference position.
[0046]
11-04-2019
12
Further, the voice adjustment device may further include a threshold setting unit that sets a
threshold in the filter unit 14a, and an averaging section setting unit that sets the length of each
section in which the averaging processing unit 14b performs averaging. .
[0047]
Second Embodiment The voice adjustment device according to the second embodiment
corresponds to the upper concept of the first embodiment.
The present embodiment is characterized by automatically controlling various operators for
performing adjustment operations on various types of parameters such as the delay amount and
the audio effect as well as the audio level.
[0048]
[2-1: Configuration] FIG. 5 is a block diagram showing the configuration of the voice adjustment
device according to the second embodiment.
The voice adjustment device according to the second embodiment includes an operation unit 21,
an adjustment processing unit 22, a target value setting unit 23, and a control unit 24.
[0049]
The operation unit 21 receives a manual adjustment operation on predetermined parameters
from the operator.
The operation unit 21 is not limited to the faders of the first embodiment, and is configured to
include various operation elements such as slide type and rotary type operation switches used
for the audio control console.
Objects to be operated by the operation unit 21 are various parameters to be provided to the
11-04-2019
13
audio signal such as an audio level and a delay amount. When the user moves the operation
element assigned to the predetermined parameter of the operation unit 21 by a predetermined
amount, a signal corresponding to the operation amount is sent to the adjustment processing
unit 22.
[0050]
The adjustment processing unit 22 executes various processes such as sound quality, audio
effect, and delay processing on the input audio signal based on the adjustment operation
received by the operation unit 21. For example, in the case where the parameter set in advance
in the operation unit 21 is a fader that performs an adjustment operation regarding delay
processing of an audio signal, the adjustment processing unit 22 performs delay processing on
the input audio signal.
[0051]
The target value setting unit 23 sets a target value of the above parameter. The operator inputs
this target value from an input unit such as a setting switch installed in the voice adjustment
device. The target value setting unit 23 sets a target value by storing the target value of the
parameter. In another mode, the target value setting unit 23 inputs target value data sent from a
host terminal connected to the voice adjustment device, and stores the target value data in a
memory in the device to set the target value. Do.
[0052]
The control unit 24 performs adjustment necessary for the operation unit 21 so that the value of
the parameter of the audio signal after the adjustment processing in the adjustment processing
unit 22 matches the target value of the parameter set by the target value setting unit 23. Control
is performed to present the amount of operation to the operator. As a method of this
presentation, in addition to the method of making the operator visually recognize the operation
amount according to the position of the operation element as in the embodiment 1, the numerical
display such as liquid crystal display panel etc., analog display such as meter etc. Is also possible.
[0053]
11-04-2019
14
[2-2: Operation] FIG. 6 is a flowchart showing the flow of the operation of the voice adjustment
device according to the second embodiment.
[0054]
The target value setting unit 23 sets target values of various parameters such as an audio level
and a delay amount (step S201).
This work is performed in advance at the stage of rehearsal and the like. The target value setting
unit 23 sets the above-mentioned target values by storing target value data of the input various
parameters in a memory in the apparatus. Note that there may be a plurality of parameters or
only one parameter for setting the target value.
[0055]
When an audio signal is input from the outside of the device in this state, the control unit 24
checks each parameter of the input audio signal, and the difference amount between the target
setting value and the parameter, that is, the adjustment operation amount by the operation unit
21 decide. (ステップS202)。
[0056]
Next, the control unit 24 presents the operator with the amount of adjustment operation
required by the operation unit 21 so that the value of the parameter in the audio signal after
adjustment processing matches the target value set in step S201. Control to
[0057]
By the control performed by the control unit 24, operation contents necessary for the value of
the parameter after adjustment processing in the adjustment processing unit 22 to coincide with
the target value are presented to the operator in accordance with the operation form in the
operation unit 21. (Step S203).
[0058]
11-04-2019
15
[2-3: Effects] The voice adjustment device according to the second embodiment presents the
operator with the contents of the operation required to achieve the target value.
Therefore, the operator can easily achieve the target value by manually performing the
adjustment operation on the operation unit 21 according to the content of the operation.
Therefore, according to the voice adjustment device according to the second embodiment, it is
possible to prevent an operator who is not used to the operation from performing an erroneous
operation.
[0059]
Under the current situation where the number of monitoring points in the voice adjustment work
is increasing, simply displaying the numerical value of the target value on the display separately
disposed on the console is insufficient for reducing the workload of the operator. This is because
the operator is forced to sequentially check the target value displayed on the display and adjust
operation at the operation unit, so the amount of work increases and the burden increases.
[0060]
In addition, when the operator's skill level is low, it is necessary to display 20 dB as the target
volume amplification factor value on the display, or 150 ms as the target delay amount value. do
not become. In such a presentation form, it is difficult for an unskilled operator to understand
what adjustment operation actually needs to be performed in a short time, and an appropriate
operation can not be performed.
[0061]
The voice adjustment device according to the second embodiment presents, using the operation
unit 21 itself, an adjustment operation amount necessary to realize a target value set in advance
for each parameter. Therefore, the operator only needs to perform the adjustment operation for
the adjustment operation amount presented by the operation unit 21 as it is, and it is possible to
11-04-2019
16
perform an appropriate operation with a simple operation.
[0062]
Third Embodiment [3-1: Configuration] FIG. 7 is a block diagram showing a configuration of a
voice adjustment device according to a third embodiment. The audio adjustment device includes
an operation unit 21, an adjustment processing unit 22, a target value setting unit 23, a control
unit 24, an audio signal input unit 30, and an audio signal output unit 31. The control unit 24
includes a parameter detection unit 32, a relative value calculation unit 33, and a presentation
control unit 34.
[0063]
The audio signal input unit 30 inputs an audio signal from the outside of the device. The audio
signal input unit 30 sends the input audio signal to the subsequent adjustment processing unit
22. The audio signal output unit 31 outputs the audio signal subjected to the adjustment
processing by the adjustment processing unit 22 to the outside of the apparatus.
[0064]
The parameter detection unit 32 detects the value of the parameter of the audio signal on which
the adjustment processing has been performed by the adjustment processing unit 22. For
example, if the parameter of the adjustment process performed by the adjustment processing
unit 22 is an audio level, the parameter detection unit 32 detects the audio level of the audio
signal after the level adjustment process. When the parameter of the adjustment process
performed by the adjustment processing unit 22 is the delay amount, the delay amount of the
audio signal after the delay process is detected.
[0065]
The relative value calculation unit 33 calculates the relative value of the parameter based on the
value detected by the parameter detection unit 32 and the target value set by the target value
setting unit 23. The relative value calculation unit 33 sends the calculated relative value to the
11-04-2019
17
presentation control unit 34.
[0066]
The presentation control unit 34 performs control of presenting the adjustment operation
amount in the operation unit 21 corresponding to the relative value calculated by the relative
value calculation unit 33 to the operator using the operation unit 21.
[0067]
[3-2: Operation] Based on the adjustment operation received by the operation unit 21, the audio
signal subjected to the adjustment process for the predetermined parameter by the adjustment
processing unit 22 is sent to the parameter detection unit 32.
The parameter detection unit 32 detects the value of the parameter for the audio signal sent
from the adjustment processing unit 22, and sends the detected parameter value to the relative
value calculation unit 33.
[0068]
The relative value calculation unit 33 calculates the relative value between the target value
preset by the target value setting unit 23 and the parameter value detected by the parameter
detection unit 32, and sends the calculated relative value to the presentation control unit 34. The
presentation control unit 34 performs control of presenting the adjustment operation amount
corresponding to the received relative value to the operator using the operation unit 21. By
sending a control signal for performing the control to the operation unit 21, the operation unit
21 itself is controlled to present the amount of adjustment operation to the operator. [3-3:
Effects] By the control performed by the presentation control unit 34, according to the operation
mode of the operation unit 21, the operator needs the operation content necessary for the
parameter value of the audio signal after adjustment processing to be the target value. Will be
presented. Therefore, the operator can easily achieve the target value by manually performing
the operation for the presented adjustment operation amount.

parameter detection unit 41, the target value set by the target value setting unit 23, and the
value of the adjustment process executed by the adjustment processing unit 22. , Calculate the
relative value in the parameter.
[0072]
The target value set by the target value setting unit 23 is, as in the second embodiment, a target
value for the parameter in the audio signal after the adjustment processing is performed by the
adjustment processing unit 22.
Therefore, the value obtained by subtracting the parameter value detected by the parameter
detection unit 41 from the target value set by the target value setting unit 23 is all adjustment
required by the adjustment processing unit 22 to realize the target value. Corresponds to the
value of the process. The relative value calculation unit 42 further subtracts the value of the
adjustment processing currently performed by the adjustment processing unit 22 from this value
to adjust the adjustment processing unit 22 additionally required to achieve the target value. The
value of the process is calculated as the relative value.

[0073]
The relative value calculation unit 42 specifies the value of the adjustment process performed by
the adjustment processing unit 22 based on the operation signal sent when the manual
adjustment operation is received from the operation unit 21. The value of the adjustment
processing performed by the adjustment processing unit 22 is determined based on the
operation signal from the operation unit 21. Therefore, the relative value calculation unit 42 uses
the operation signal output from the operation unit 21 to obtain the value of the adjustment
process.
[0074]
The presentation control unit 34 performs control of presenting the adjustment operation
amount in the operation unit 21 corresponding to the relative value calculated by the relative
value calculation unit 42 to the operator using the operation unit 21 itself. By the control
performed by the presentation control unit 34, the operation content necessary for the
parameter value of the audio signal after the adjustment process to become the target value is
presented to the operator in accordance with the operation form in the operation unit 21.
[0075]
The voice adjustment device according to the present embodiment detects the value of the
parameter of the voice signal before the adjustment process. Also in the configuration, the
relative value is obtained by subtracting the value of the detected parameter from the target
value set in advance and the value of the adjustment process already performed by the
adjustment processing unit 22 based on the current operation state. Can be calculated.
[0076]
By presenting the amount of adjustment operation corresponding to the calculated relative value
to the operator, the operation of adjusting the sound becomes easy, and the burden on the
operator and the prevention of erroneous operation can be realized. Therefore, the operator can
11-04-2019
