Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, when recording a voice, automatically records the playback condition information used when playing back the recorded voice in parallel and makes it possible to utilize the information for setting the sound field at the time of playback. The present invention relates to a sound field setting device.

[0002]

[Prior art]

 Conventionally, when recording audio, it was not possible to specify the playback conditions (for example, having a graphic equalizer characteristic or having a surround effect) used when playing back the recorded audio. Fick equalizer, surround processor, etc. were used to set arbitrary playback conditions.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional recording method requires operation of sound field setting (in surround mode) and sound quality setting (in the graphic equalizer characteristic, etc.) at the time of reproduction, which is troublesome and provides an optimum sound quality and sound field for reproduction. I couldn't get it. The object of the present invention is to solve the above-mentioned conventional problems, to record the reproduction condition information used when reproducing the recorded voice in parallel and to record the information when reproducing the voice. It is an object to provide an automatic sound field setting device that can synchronously read and automatically set playback conditions.

[0004]

[Means for Solving the Problems]

 An automatic sound field setting device according to the present invention comprises a sound data recording / reproducing device, a system control data recording / reading device which is synchronously controlled with the recording / reproducing device, and a sound field and / or sound quality setting device. A system control microprocessor for controlling the synchronous operation of the recording / playback device and the recording / reading device and for controlling transfer of the sound field and / or sound quality setting data from the sound field and / or sound quality setting device as system control data. It has and.

[0005]

[Action]

 Using two recording media, one of the recording media is used to record the sound, and at the time of recording the sound, a sound effect desired to be added when reproducing the sound, for example, a surround effect such as a hall environment or a live environment, System control data for sound quality effects such as graphic equalizer characteristics are synchronously recorded on the other recording medium. At the time of audio reproduction, two recording media are operated synchronously, and the system control data prerecorded in synchronization with the audio reproduction are read synchronously to provide the desired sound field and sound quality effect characteristics.

【Example】

 One embodiment of the automatic sound field setting device according to the present invention will be described with reference to the basic configuration diagram of FIG. 1 and the specific configuration diagram of FIG. In FIG. 1, 1 is a system control microprocessor, 2 is a voice recording / reproducing device, 3 is a system control data recording / reading device, 4 is a sound field / sound quality setting device, and 5 is a recording source. First, at the time of recording, the desired sound field / sound quality is set in advance in the sound field / sound quality setting device 4 at the time of reproduction. Next, at the same time as the recording of the voice data by the voice recorder / player 2 starts, the system control data (the sound field set in the sound field / sound quality setting device 4 described above is controlled based on the control of the system control microprocessor 1). Sound quality condition data) is recorded together with the identification code by the system control data recording / reading device 3. On the other hand, at the time of reproduction, at the start of reproduction, the system control data recording / reading device 3 is first reproduced so that the system control microprocessor 1 reads the system control data and controls the sound field / sound quality setting device 4. When the end of data transfer is detected, the audio data recording / playback device 2 starts playing. In this way, when the voice is reproduced, the reproduction is performed with the reproduction condition of the desired sound field and / or sound quality added.

The above-mentioned “identification code” cannot be used with other recording / reproducing machines, although recording software such as tapes and disks recorded / recorded by the automatic sound field setting device of the present invention cannot be used. This is a code signal for enabling only the automatic sound field setting device having the configuration of the present invention to perform a predetermined operation by detecting this identification code. FIG. 2 is a block diagram showing the configuration of FIG. 1 more concretely. A CD (compact disc) player 51 as a recording source 5, an audio recording / reproducing device 2 and an MD (recording / reading device 3 for system control data). This is a case where a graphic equalizer (or surround processor) 41 is used as the mini disk player 21, 31, and the sound field / sound quality setting device 4. The "MD (mini disk)" is a recordable and reproducible magneto-optical disk having a diameter of about 64 mm.

In FIG. 2, the audio data from the CD player is recorded on the first recording medium MD 1 by the MD player 21, and at the same time, the equalizer characteristic (or surround characteristic) preset by the graphic equalizer (or surround processor) 41 is used. The sound field / sound quality setting data is recorded together with the identification code by the MD player 31 under the control of the system control microprocessor 1 in synchronization with the second recording medium MD2. At the time of reproduction, first, the system control data is read from the second recording medium MD2 by the MD player 31 and transferred to the graphic equalizer (or surround processor) 41, and the equalizer characteristic (or the smoother characteristic set at the desired recording time) is set. Sound characteristics) are set. After the transfer is completed, the audio data is reproduced by the MD player 21 from the first recording medium MD1 in a form in which the desired equalizer characteristic (or surround characteristic) is added.

As described above, according to the automatic sound field setting device using a plurality of recording media according to the present invention, it is necessary to perform sound field setting (surround mode) / sound quality setting operation when playing back recorded sound. Instead, simply by setting the playback software and system control software on two playback devices that operate in synchronization, the playback state is automatically set based on the playback conditions set during recording, and the sound field during playback is set. The key operation for setting can be omitted. In addition, if an ID code for identifying the type of recording source and song number, etc. is added to the system control data, the system corresponding to the reproduced song can be used without converting the system control data file each time the playback software is changed. It is possible to read control data. In the above description, an MD (mini disk) player is used as the audio recording / reproducing device 2 and the system control data recording / reading device 3, but the present invention is not limited to this, and a tape deck, an MD player, a DAT (digital audio device) are used. Of course, a tape recorder), a CD player, and the like can be used in any combination.

[Effect of device]

 The automatic sound field setting apparatus using a plurality of recording media according to the present invention does not require operation of sound field setting (surround mode) / sound quality setting when playing back recorded sound, and the playback software and By simply setting the system control software on two playback devices that operate in synchronization, the playback state is automatically set based on the playback conditions set in advance during recording, and a key for setting the sound field during playback is set. The operation can be omitted. In addition, a two-disc set of voice recording software (tape, disk, etc.) and system control data recorded software (tape, disk, etc.) created in advance using the same device as the automatic sound field setting device of the present invention. Even if the software is on the market, it can be supported.
