The miking device 126 includes an acoustic signal acquisition unit, a reception unit, a control unit 202, and an output unit. Specifically, for example, the miking apparatus 126 is a mixer having functions for miking work and mixing work.

The acoustic signal acquisition unit acquires each acoustic signal from a plurality of sound collection devices that collect sound and output each as an acoustic signal. Specifically, for example, the acoustic signal acquisition unit acquires the acoustic signals output from the first to third

sound collection devices

114, 116, and 118 via the first to

third amplifiers

120, 122, and 124. . The acoustic signal acquisition unit has first to third input channels. The first input channel is connected to the first amplifier 120 by a wire, and acquires the acoustic signal output from the first amplifier 120.

The third input channel is connected to the third amplifier 124 by wire, and acquires the acoustic signal output from the third amplifier 124.

The accepting unit accepts an instruction to switch acoustic signals remotely. Specifically, for example, the reception unit receives an instruction to output, to the headphones 104, the acoustic signal input to the first input channel among the acoustic signals input to the first to third input channels.

Further, the reception unit may receive an instruction to select one acoustic signal based on an acoustic signal generated by a sound that a user has touched the surfaces of a plurality of sound collection devices. Specifically, for example, the reception unit is based on an acoustic signal obtained by converting a sound (hereinafter referred to as a click sound) generated when a user rubs a windscreen surface of a microphone with a nail (hereinafter referred to as a click). Thus, an instruction to select an acoustic signal may be received.

The control unit 202 includes a selection unit 204 and a delay unit 206 as shown in FIG. The selection unit 204 has a click sound detection unit 208. The selection unit 204 selects one acoustic signal from the plurality of acoustic signals based on the instruction or each acoustic signal acquired from the plurality of sound collection devices. Specifically, for example, when the instruction received by the reception unit includes information indicating that the acoustic signal input to the first channel is output, the selection unit 204 selects the acoustic signal input to the first input channel. To do.

In addition, when the reception unit receives an instruction to select one acoustic signal based on the acoustic signal generated by the click sound, the selection unit 204 outputs the sound from the sound collection device to which the click sound is input. Selected acoustic signals may be selected. Specifically, for example, the miking device 126 stores in advance, as a reference signal, an acoustic signal obtained by converting sound generated when a user rubs the windscreen surface of a microphone with a nail. The click sound detection unit 208 compares each sound signal input to each input channel with the reference signal, and detects the sound signal if there is an approximate sound signal. The selection unit 204 may select the detected acoustic signal.

A plurality of reference signals may be stored. Specifically, the miking device 126 may store in advance, as a reference signal, a sound generated when the surfaces of a plurality of wind screens having different shapes are rubbed with a nail. In this case, the click sound detection unit 208 may compare each acoustic signal input to each input channel with all reference signals stored in advance, and select an approximate acoustic signal.

The delay unit 206 controls the time (hereinafter referred to as delay time) from when the acoustic signal acquisition unit is acquired until the output of the selected acoustic signal is started. Specifically, for example, the delay unit 206 performs control so that the acoustic signal acquired by the acoustic signal acquisition unit is output without delay. The delay unit 206 may be controlled so that the acoustic signal acquired by the acoustic signal acquisition unit is output a few seconds after the acoustic signal is acquired.

Also, the control unit 202 controls whether the miking device 126 is in the mixing mode or the miking mode. Specifically, when the miking device 126 is in the mixing mode, the control unit 202 controls the miking device 126 to function as a mixer. That is, the user operates various panel operators provided in the miking device 126. As a result, the miking device 126 performs mixing, adjustment of sound quality, and the like on the acoustic signals input to the first to third input channels, and outputs them to the headphones 104. When the miking device 126 is in the miking mode, the miking device 126 outputs one acoustic signal selected as described above.

In addition, when the instruction received by the reception unit includes information indicating that one acoustic signal is selected by the click sound, the control unit 202 performs control so as to select the acoustic signal detected by the click sound detection unit 208.

The output unit outputs the selected acoustic signal to the headphones 104 by wireless communication. Specifically, the output unit is connected to the information processing apparatus 106 by a low-delay wireless connection method. The output unit outputs the acoustic signal selected by the selection unit 204 to the headphones 104 via the wireless connection.

The output unit may output the selected acoustic signal after a preset time has elapsed since the acoustic signal was acquired. Specifically, when the delay unit 206 controls the sound signal to be output 3 seconds after the sound signal is acquired, the output unit 3 seconds after the selected sound signal is acquired, The acoustic signal may be output to the headphones 104.

The headphone 104 converts the acquired acoustic signal into sound. Specifically, the headphones 104 convert an acoustic signal, which is an electrical signal acquired from the output unit, into a sound that can be heard by the miking worker 102. The headphones 104 are worn by the miking worker 102.

The information processing device 106 instructs the miking device 126. Specifically, for example, the information processing apparatus 106 is a tablet terminal, a smartphone, a notebook PC (Personal Computer), or the like. The information processing device 106 generates a sound collection device switching instruction according to the operation of the miking worker 102. The information processing device 106 is connected to the miking device 126 by, for example, Bluetooth (registered trademark) and outputs the instruction. Further, the information processing apparatus 106 may output information regarding the delay time to the miking apparatus 126. Information regarding the delay time is generated when the miking operator 102 operates the information processing apparatus 106.

Subsequently, a miking work method using the headphones 104 will be described. In the state where the environment shown in FIG. 1 is prepared, the miking worker 102 starts miking work.

First, the miking worker 102 operates the tablet terminal so that the miking device 126 enters the miking mode. Based on the operation, an instruction to enter the miking mode is generated and output to the miking device 126. The miking device 126 operates as a miking mode upon acquiring the instruction. The miking worker 102 may directly operate the miking device 126 so that the miking device 126 enters the miking mode.

Next, an instruction to switch the acoustic signal is received remotely. Specifically, for example, the miking worker 102 operates the tablet terminal so that the miking device 126 is in the designated mode. At this time, the miking worker 102 selects the acoustic signal input to the first input channel as the acoustic signal to be output. Based on the operation, the tablet terminal generates an instruction including information indicating that the miking device 126 is set to the designated mode and that the first input channel is designated, and outputs the instruction to the miking device 126.

Note that the miking worker 102 may operate the tablet terminal so that the miking device 126 enters the click sound mode. Specifically, the miking worker 102 operates the tablet terminal so that the miking device 126 enters the click sound mode. Based on the operation, the tablet terminal generates an instruction including information indicating that the miking device 126 is in the click sound mode, and outputs the instruction to the miking device 126.

Also, the miking worker 102 performs an operation for setting a delay time on the tablet terminal. Specifically, for example, an operation for setting the delay time after 3 seconds to the tablet terminal is performed. Based on the operation, the tablet terminal generates an instruction including information indicating that the delay time is 3 seconds later, and outputs the instruction to the miking device 126.

The miking device 126 that has acquired the above instructions operates as a mode based on the instructions.

Next, a plurality of sound signals are acquired from a plurality of sound collecting devices that collect sound and output as sound signals. Specifically, the guitar player 108 performs in front of the first sound collection device 114 after clicking the first sound collection device 114. At the same time, the drum performer 110 may perform in front of the second sound collection device 116, and the bass player 112 may perform in front of the third sound collection device 118. The first to third

sound collection devices

114, 116, and 118 convert sounds around the first to third

sound collection devices

114, 116, and 118 into acoustic signals and send them to the first to

third amplifiers

120, 122, and 124. Output. The miking device 126 acquires the acoustic signal amplified by the first to

third amplifiers

120, 122, and 124.

Next, one acoustic signal is selected from the plurality of acoustic signals based on the instruction or each acoustic signal acquired from the plurality of sound collecting devices. Specifically, for example, when the miking device 126 is in the designation mode and the first input channel is designated, the selection unit 204 selects the acoustic signal input to the first input channel.

Also, when the selection unit 204 is in the click sound mode, the click sound detection unit 208 compares each acoustic signal input to each input channel with the reference signal, and detects an approximate acoustic signal. The selection unit 204 selects the detected acoustic signal. Specifically, for example, since the guitar player 108 clicks on the first sound collection device 114, the click sound detection unit 208 detects an acoustic signal input to the first input channel. The selection unit 204 selects the detected acoustic signal of the first input channel.

Next, the selected acoustic signal is output to the headphones 104 by wireless communication. Specifically, for example, the output unit outputs the acoustic signal input to the first input channel to the headphones 104 by low-delay wireless communication. When the delay time is set to be 3 seconds later, the output unit outputs the sound signal obtained by converting the performance sound by the guitar player 108 with a delay of 3 seconds.

Finally, the miking worker 102 adjusts the position and angle of each sound collection device while listening to the sound output from the headphones 104. The miking worker 102 adjusts the microphone position and the like while the guitar player 108 is playing. Therefore, even if the miking worker 102 wears the headphones 104, the live performance sound may be heard in addition to the sound output from the headphones 104. However, since the delay time is set to 3 seconds, the miking operation can be performed by distinguishing between the performance sound by the guitar player 108 and the sound output from the headphones 104.

As described above, even if there is no person who confirms the sound recorded in the separate room when the miking worker 102 instructs the miking apparatus 126 by the information processing apparatus 106, one miking is performed. The worker 102 can easily perform miking work.

The volume detection unit 302 detects an acoustic signal representing a sound larger than a preset volume from the acoustic signal acquired by the acoustic signal acquisition unit. Specifically, for example, the miking device 126 stores information related to a preset volume. The volume detector 302 compares the volume represented by each acoustic signal input to each input channel with a preset volume, and detects an acoustic signal larger than the preset volume. The selection unit 204 selects the detected acoustic signal.

In addition, after the selection unit 204 selects the acoustic signal detected by the volume detection unit 302, when the volume detection unit 302 detects the acoustic signal input to another input channel, the selection unit 204 is detected later. An acoustic signal may be selected, or an acoustic signal detected first until the reception unit acquires a new instruction may be selected.

The control unit 202 is in a designated mode when the miking device 126 is in the miking mode, or is a mode in which the selection unit 204 selects an acoustic signal detected by the volume detection unit 302 (hereinafter referred to as volume detection mode). Control. Specifically, the reception unit receives an instruction to select, as one acoustic signal, an acoustic signal that represents a sound larger than a preset volume among the acoustic signals output from each sound collection device. In this case, the control unit 202 controls the miking device 126 so as to select the acoustic signal detected by the volume detection unit 302.

The miking worker 102 operates the tablet terminal so that the miking device 126 enters the sound volume detection mode. Based on the operation, the tablet terminal generates an instruction to set the miking device 126 to the sound volume detection mode and outputs the instruction to the miking device 126. In response to the instruction, the miking device 126 operates in the sound volume detection mode.

According to this modification, when performing a miking operation on a plurality of sound collection devices, the operation can be performed efficiently. Specifically, for example, first, the miking worker 102 adjusts the microphone position and the like while the guitar player 108 is performing. Subsequently, the guitar player 108 stops playing and the drum player 110 starts playing.

Here, when the sound represented by the acoustic signal input to the second input channel is larger than the preset volume, the selection unit 204 selects the acoustic signal input to the second input channel. The selected acoustic signal, that is, the acoustic signal converted by the sound collecting device arranged in front of the drum performer 110 is output to the headphones 104. Therefore, the miking worker 102 can continuously adjust the position of the microphone arranged in front of the drum performer 110 without operating the tablet terminal or the like.

The control unit may have both a click sound detection unit and a volume detection unit.

Further, the miking device 126 may have a noise canceling function. Specifically, for example, the miking apparatus 126 may output the selected acoustic signal to the headphones 104 after performing a process of reducing noise using a conventional technique. Further, the miking device 126 may validate the noise canceling function only when in the mixing mode, and invalidate when in the miking mode.
