DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically reproducing the acoustic characteristics of an audio signal recorded in advance in an audio mixer, 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 pre-recorded audio signal are changed over time, the changed state is stored in advance, and in the automatic reproduction mode, the acoustic characteristics are changed as previously stored. It is to let.

When such a recall type audio mixer device is used in a recording studio or the like, it may be necessary to readjust the sound characteristics while listening to the reproduced sound during the automatic reproduction mode. For example, a different musical instrument sound is recorded for each channel of a magnetic tape, this tape is reproduced, each channel of the reproduced output is input to each channel of the mixer device, and the mixer device progresses according to the progress of the tape reproduction. When the operation of the above, that is, the adjustment of the acoustic characteristics is automatically reproduced and monitored, the operator sometimes thinks that the level of the instrument sound of a certain channel is to be increased or decreased for a certain section and further.

In such a case, in a conventional recall type audio mixer apparatus, when a portion of a channel whose level is to be changed is being reproduced during automatic reproduction, the user touches a fader knob for adjusting the level of the channel. Then, the touch sensor operates, and the level adjustment of the channel is released from the automatic reproduction mode, and the level adjustment is based on the operation of the fader for level adjustment of the channel. When the fader is operated variously in this state, the history of the operation is stored in the memory, and can be combined with another channel and reproduced as recorded later.

[0005]

However, after canceling the automatic reproduction mode, it is necessary to variously operate the fader in order to search for the optimum level, and the entire process of this operation is recorded in the memory. Therefore, even if this operation process stored in the memory is directly synthesized with another channel and reproduced, the desired state cannot be obtained. Therefore, after finding the optimal level, adjust the level of that channel to the optimal level position, automatically play the tape again from the beginning, and when the part you want to achieve this optimal level is played, use the fader knob It is necessary to perform an operation of canceling the automatic reproduction mode by touching with a hand, and there has been a problem that such an operation is very troublesome and troublesome.

[0006]

According to the present invention, there is provided a storage means for storing information for automatically reproducing acoustic characteristics of an audio signal in a time series, and an operation element for generating information for adjusting the acoustic characteristics of the audio signal. In the automatic reproduction mode, the acoustic characteristics of the audio signal are reproduced over time based on the information for automatic reproduction stored in the storage means, and reproduced in the manual adjustment mode based on the information for automatic reproduction. Reproducing means for changing the acoustic characteristics of the audio signal based on information for adjusting the acoustic characteristics from the operator, mode switching means for switching from the automatic reproduction mode to the manual adjustment mode, and various types of the manual adjustment mode. Storage command means for storing and commanding a desired one of a plurality of pieces of information for adjusting acoustic characteristics generated by the operated operator. A section designating section for designating a section in which an audio characteristic is replaced with an acoustic characteristic based on the acoustic characteristic adjustment information stored by the storage command section in the audio signal reproduced in the automatic reproduction mode; Means for storing new automatic reproduction information obtained by replacing the automatic reproduction information in the section designated by the storage command means with the acoustic characteristic adjustment information stored by the storage command means in the storage means. It is.

[0007]

According to the present invention, when the reproducing means reproduces the audio characteristics of the audio signal in the automatic reproduction mode, when the section in which the acoustic characteristics are to be changed is reached, the mode switching means is switched to the manual adjustment mode. Then, the operator operates the operator to change variously the acoustic characteristics of the audio signal reproduced by the reproducing means. Then, when the desired acoustic characteristics can be adjusted, the storage command means is operated to store the acoustic characteristic adjustment information generated by the operator at that time. Then, the section of the audio signal to be replaced with this information is specified by the section specifying means. Thus, the storage unit stores the automatic reproduction information in which the specific section is replaced with the sound adjustment information from the operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, as shown in FIG.
(Digital signal processing device) 10. This D
The SP 10 has a plurality of input channels ch1 to chn, and separate instrument sounds recorded on each channel of a tape recorder (not shown) are input to these channels ch1 to chn. DSP10 is a CPU
After adjusting the acoustic characteristics of the instrument sound of each input channel based on the acoustic characteristic control information, for example, information relating to the level and frequency characteristics supplied from 12, the resultant is synthesized with the left signal L and the right signal R, respectively, and output. I do.

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

In the automatic reproduction information recording mode, when each of the operation groups 161 to 16n is operated, for example, in accordance with the progress of the tape reproduction, each operation of each operation group will be CPU 1 stores an operation history indicating what operation has been performed when a certain time has elapsed.
2 and stored in the memory 14. The reproduction information stores information indicating which channel of the operated operator is operated and how it is operated, and the time when the operation is performed. This time can be known, for example, from the count value of a counter that has started counting from the start of tape playback.
Note that the count value may be stored in the tape in advance like a time code. In this case, the count value is read from the tape and can be used.

The CPU 12 reads the information for automatic reproduction thus obtained from the memory 14 and supplies it to the DSP 10, so that the acoustic characteristics of the audio signal of each channel are automatically adjusted. For example, the counter for automatic reproduction starts counting from the start of tape playback, and searches for information for automatic reproduction having a count value corresponding to the count value of the counter for automatic reproduction that changes sequentially and is included in the information. The automatic reproduction is performed by supplying the DSP 10 with the acoustic characteristic information of the channel in question. Such an operation that is automatically reproduced is called an automatic reproduction mode.

The faders 181 to 18n and the knobs 201 to 20 of the operation units 161 to 16n are provided.
n, 221 to 22n, a touch sensor (not shown)
When a finger touches these knobs, a manual adjustment mode is set, the automatic reproduction mode of the channel to which the knob touched belongs is released, and the CPU 12 sends the acoustic characteristic control information according to the operation of the knob to the CPU 12. , 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 to replace the acoustic characteristic information stored in the memory 14 by operating the switch 24. It is specified.

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

As a result of such a change, when a desired level is determined in a certain section, the switch 2
By operating the CPU 4, the CPU 12 causes the memory 14 to store the acoustic characteristic information P necessary for generating the level in this channel.

Next, when the input device 26 is operated to supply the CPU 12 with information representing the sections CO and C1 having the above-mentioned levels, the sections CO to C in the automatic reproduction information are obtained.
New acoustic characteristic information in which the acoustic characteristic information relating to level 1 is replaced with acoustic characteristic information P from which the above-mentioned level is obtained is created and stored in the memory 14.

This section can be determined by the value of the counter used for automatic reproduction. For example, assuming that the count value at the start of the 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 calculates the count value 2 of the previous automatic reproduction information.
New acoustic reproduction information is created by replacing the acoustic characteristic information relating to the level of the operated channel in the section corresponding to 0 to 30 with the above P.

In this case, the automatic reproduction information is stored in the memory 14. This is for comparing the new automatic reproduction information with the previous automatic reproduction information.

When automatic reproduction is performed based on the new information for automatic reproduction thus obtained, the level of the channel is set to a desired level during the interval C0 to C1, as shown in FIG. It is said.

In order to create new automatic reproduction information, the CPU 10 operates as shown in the flowchart of FIG. It is assumed that the previously created information for automatic reproduction is stored as file A. In addition, for simplicity, the description will be made on the assumption that only the volume level is adjusted.

First, automatic reproduction is instructed to the DSP 10 in the automatic reproduction mode according to the file A (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, automatic reproduction is performed in the automatic reproduction mode until touched.

If it is determined that there is a channel touched by the fader (Yes at step S), the fader adjustment (level adjustment) of the touched channel is set to a 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 dashed line in FIG. Then, a desired level is determined during this adjustment.

Then, it is determined whether the switch 24 has been operated (step S8). If the switch 24 has not been operated (No at Step S8), Step S8 is repeated until the switch 24 is operated. When the switch 24 is operated (Yes at 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 time C0 and the end time C1 of the section having the desired level have been input by the input device 26 (step S12). If the input has not been made (No at Step S12), Step S12 is repeated until the input is made.

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

When the automatic reproduction is performed in the automatic reproduction mode in accordance with the file B created in this manner, the level of the channel touched by the fader is set to the level represented by P only during the period C0 to C1. .

In the above embodiment, only the case where the volume level is adjusted by the fader has been described. However, the present invention is not limited to this case. The adjustment of various acoustic characteristics can be performed in the same manner as in the above-described embodiment. 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. However, a separate switch may be provided.

[0029]

As described above, according to the present invention, switching from the automatic reproduction mode to the manual adjustment mode allows various operations.
As a result of operating the child, when the acoustic characteristics are brought to the desired state,
By the storage command means, the desired acoustic characteristics are stored,
A new automatic reproduction in which the section having the acoustic characteristics is designated by the section designating means, and the information for automatic reproduction of the section designated by the section designating means is replaced with the information for acoustic characteristic adjustment stored by the command means. Since the application information is stored in the storage means, the trouble in adjusting the acoustic characteristics is significantly reduced as compared with the conventional one, and the efficiency is improved.
