Abstract

PURPOSE:To facilitate the change of audio characteristics to be automatically reproduced. CONSTITUTION:In an automatic reproducing mode, a DSP 10 reproduces the audio characteristics of an audio signal based on information for automatic reproduction in a memory 14. When any one of faders 181-18n is touched during this automatic reproducing mode, the level adjustment of a channel to which that fader belongs is turned to a manual adjustment mode, and the level is changed by operating that fader. When the desired level is provided by this change, audio information for providing that level is stored by operating a switch 24. Next, the block to be turned to this level is designated by an input device 26. The new information for automatic reproduction, for which the information for automatic reproduction of the block designated by the input device 26 is replaced with the information for audio characteristic adjustment stored by the switch 24, is stored in the memory by a CPU 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio mixer apparatus for automatically reproducing the acoustic characteristics of a prerecorded audio signal, and more particularly to adjusting the acoustic characteristics of the reproduced audio signal.

[0002]

2. Description of the Related Art Conventionally, there is a recall type audio mixer device. This is because, for example, when the acoustic characteristics of a prerecorded audio signal are changed over time, the changing state is stored in advance and the acoustic characteristics are changed as previously stored in the automatic reproduction mode. It is what makes me.

When such a recall type audio mixer device is used in a recording studio or the like, it may be desired to readjust the acoustic characteristics while listening to the reproduced sound in the automatic reproduction mode. For example, a different musical instrument sound is recorded for each channel of the magnetic tape, this tape is played back, each channel of this playback output is input to each channel of the mixer device, and the mixer device follows the progress of the tape playback. When the operation of, that is, the adjustment of the acoustic characteristics is automatically reproduced and monitored, the operator may consider that the level of the musical instrument sound of a certain channel should be increased or decreased only in a certain section.

In such a case, in the conventional recall type audio mixer device, when a portion of a certain channel whose level is to be changed is being reproduced during automatic reproduction, the fader knob for adjusting the level of that channel is touched. Then, the touch sensor operates, and the level adjustment of the channel is based on the operation of the fader for level adjustment of the channel, with the automatic reproduction mode being canceled. When the fader is operated variously in this state, the history of the operation is stored in the memory, and can be reproduced by combining with other channels as recorded later.

[0005]

However, after canceling the automatic reproduction mode, it is necessary to operate the fader variously in order to search for the optimum level, but the process of this operation is recorded in the memory. Therefore, even if the process of this operation stored in the memory is directly reproduced by combining it with another channel, the desired state cannot be obtained. Therefore, after finding the optimum level, adjust the level of that channel to the optimum level position, automatically play the tape again from the beginning, and when the part you want to reach this optimum level is played, use the fader knob. There is a problem in that it is necessary to touch it by hand to release the automatic reproduction mode, and such work is very cumbersome and troublesome.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and includes storage means for storing information for automatic reproduction of acoustic characteristics of an audio signal, and the audio signal of the audio signal. A manipulator that generates information for adjusting acoustic characteristics, and an audio signal is reproduced based on the information for automatic reproduction in the automatic reproduction mode, and the acoustic characteristics of the reproduced audio signal are reproduced in the manual adjustment mode from the operator. Reproduction means for changing based on information for characteristic adjustment, mode switching means between the automatic reproduction mode and the manual adjustment mode, and information for acoustic characteristic adjustment from the operator operated in the manual adjustment mode. Storage command means for commanding storage, and audio stored by the storage command means in the audio signal reproduced in the automatic reproduction mode. Section specifying means for specifying a section for replacing the acoustic characteristic with the acoustic characteristic based on the information for sex adjustment, and the acoustic characteristic stored by the commanding means for the automatic reproduction information of the section designated by the section designating means. Means for storing new automatic reproduction information replaced with the adjustment information in the storage means.

[0007]

According to the present invention, when the reproducing means reproduces the acoustic characteristic of the audio signal in the automatic reproducing mode, when the section where the acoustic characteristic is desired to be changed, the mode switching means is switched to the manual adjustment mode. Then, the operator is operated to variously change the acoustic characteristics of the audio signal reproduced by the reproducing means.

[Embodiment] In this embodiment, as shown in FIG.
It has a (digital signal processing device) 10. This D
The SP10 has a plurality of input channels ch1 to chn, and the respective instrument sounds recorded on the respective channels of a tape recorder (not shown) are input to these channels ch1 to chn. DSP10 is CPU
After adjusting the acoustic characteristic of the instrument sound of each input channel based on the acoustic characteristic control information supplied from 12, for example, the information about the level and the frequency characteristic, these are combined into the left signal L and the right signal R and output. To do.

The acoustic characteristic control information supplied from the CPU 12 includes, for example, information for reproducing acoustic characteristics stored in advance in the memory 14 and operator groups 161 to 16n provided on the adjusting table 16 corresponding to each channel. , CPU12 supplied to the CPU 12. Each of the operator groups 161 to 16n includes a large number of operation knobs, but in FIG. 1A, a fader knob 18 for level adjustment is used.
1 to 18n, knobs 201 to 2 for adjusting the equalizer
0n, knobs 221 to 22n for adjusting the delay time are shown.

In the automatic reproduction information recording mode, for example, when the operation groups 161 to 16n are operated in accordance with the progress of the tape reproduction, the reproduction information is reproduced by each operation group from the start of performance. When a certain amount of time has passed, the CPU 1 displays an operation history indicating what kind of operation was performed.
It is obtained by storing it in the memory 14 via 2. The reproduction information stores information indicating which channel the operated operator belongs to and how it was operated, and the time when the operation is performed. This time can be known, for example, from the count value of the counter that started counting from the start of reproducing the tape.
The count value may be stored in advance on the tape like the time code. In this case, this count value can be read from the tape and used.

The CPU 12 reads the information for automatic reproduction obtained in this way from the memory 14 and supplies it to the DSP 10 to automatically adjust the acoustic characteristics of the audio signal of each channel. For example, the automatic reproduction counter starts counting from the beginning of tape reproduction, and the automatic reproduction information having a count value corresponding to the sequentially changing count value of the automatic reproduction counter is searched for and included in that information. Automatic reproduction is performed by supplying the acoustic characteristic information of the current channel to the DSP 10. The operation that is automatically reproduced in this way is called an automatic reproduction mode.

Also, the fader knobs 181 to 18n and the knobs 201 to 20 of 161 to 16n of the respective operator groups
n, 221-222n are touch sensors (not shown)
When a hand touches these knobs, the manual adjustment mode is set, the automatic reproduction mode of the channel to which the knob touches is released, and the CPU 12 sends the acoustic characteristic control information according to the operation of the knob. , DSP10.

The CPU 12 is further provided with a switch 24. When the switch 24 is operated, the acoustic characteristic information of the channel in the manual adjustment mode is stored in the memory 14.

The CPU 12 is also provided with an input device 26. The input device 26 determines which part of the automatic reproduction information should be replaced with the acoustic characteristic information stored in the memory 14 by operating the switch 24. It is what you specify.

For example, as shown by the solid line in FIG.
When the automatic reproduction information is stored in the memory 14 so that the level of a certain channel changes, the level changes as time passes as shown by the solid line in FIG. Then, at some point, when the fader knob of this channel is touched by hand, the manual adjustment mode is set, and when the fader knob is adjusted, the level changes as shown by the chain line.

When a desired level is determined in a certain section as a result of such changes, the switch 2
The CPU 12 causes the memory 14 to store the acoustic characteristic information P required to generate the level in this channel by operating 4.

Next, when the input device 26 is operated to supply the information representing the sections CO and C1 having the above-mentioned levels to the CPU 12, the sections CO to C in the automatic reproduction information described above are supplied.
New acoustic characteristic information is created by replacing the acoustic characteristic information regarding the level of 1 with the acoustic characteristic information P for obtaining the above level, and the new acoustic characteristic information is stored in the memory 14.

This section can be determined by the value of the counter used for automatic reproduction. For example, if the count value at the start of automatic reproduction is 0, the count value of the section corresponding to C0 is 20, and the count value of C1 is 30, the CPU 12 determines that the count value 2 of the previous automatic reproduction information is 2.
New automatic reproduction information is created by replacing the acoustic characteristic information regarding the level of the operated channel in the section corresponding to 0 to 30 with the above P.

In this case, the above-mentioned automatic reproduction information is stored in the memory 14. This is for hearing comparison between the new automatic reproduction information and the previous automatic reproduction information.

When automatic reproduction is performed based on the new automatic reproduction information obtained in this way, the level of the channel is at a desired level between sections C0 and C1 as shown in FIG. 1 (c). It is said that

In order to create new automatic reproduction information in this way, the CPU 10 operates as shown in the flowchart of FIG. Note that the previously created automatic reproduction information is stored as the file A. Further, in order to simplify the explanation, it is assumed that only the volume level is adjusted.

First, according to the file A, the DSP 10 is instructed to perform automatic reproduction in the automatic reproduction mode (step S
2). Then, it is determined whether there is a channel touched by the fader knob (step S4). If there is no touched channel (No in step S4), step S4 is repeated. Therefore, until it is touched, automatic reproduction is performed in the automatic reproduction mode.

When it is determined that there is a channel touched by the fader (Yes in step S), the fader adjustment (level adjustment) of the touched channel is set to the manual adjustment mode (step S6). Therefore, since the level of this channel changes according to the operation of the fader, the level can be arbitrarily changed as shown by the alternate long and short dash line in FIG. The desired level is then determined during this adjustment.

Then, it is determined whether the switch 24 has been operated (step S8). When the switch 24 is not operated (No in step S8), step S8 is repeated until it is operated. When the switch 24 is operated (Yes in step S8), the fader adjustment level of the channel set to the manual mode is stored as P (step S10).

Next, it is determined whether the start point C0 and the end point C1 of the section having the desired level are input by the input device 26 (step S12). If it has not been input (No in step S12), step S12 is repeated until it is input.

When input (Yes in step S12), the fader adjustment level of the channel of the file A switched to the manual mode between C0 and C1 is rewritten to P as the file B and stored in the memory 14
(Step S14), and the process ends.

When automatic reproduction is performed in the automatic reproduction mode according to the file B created in this way, the level of the channel to which the fader is touched becomes the level represented by P only during the period C0 to C1. .

In the above embodiment, only the case of adjusting the volume level by the fader has been described, but the present invention is not limited to this, and the audio mixer device for adjusting the frequency characteristic by the equalizer and adjusting the pan pot is provided. The adjustment of various acoustic characteristics can be performed in the same manner as in the above-mentioned embodiment. Further, in the above-described embodiment, the switching from the automatic reproduction mode to the manual adjustment mode is performed by touching the touch sensor provided on the fader with a hand, but a switch for switching may be provided separately.

[0029]

As described above, according to the present invention, when the automatic reproduction mode is switched to the manual adjustment mode to set the acoustic characteristics to a desired state, the storage instruction means stores the desired acoustic characteristic information. Then, the section for designating the acoustic characteristic is designated by the section designating means, and the automatic reproduction information of the section designated by the section designating means is replaced with the information for adjusting the acoustic characteristic stored by the command means. Since the information for automatic reproduction is stored in the storage means,
The time required for adjusting the acoustic characteristics is much less than that of the conventional one, and the efficiency is improved.
