[Conventional technology]

2. Description of the Related Art In recent years, various stereo apparatuses such as component stereos incorporate a signal processing apparatus such as a graphic equalizer or a reverberation adding apparatus. Such a stereo device can reproduce music with various sound qualities as compared with a conventional device in which sound quality can be adjusted only to the extent of tone control, and the user can adjust the frequency characteristics and the state of adding reverberant sounds. Thus, the sound can be reproduced with an arbitrary sound quality.

[Problems to be solved by the invention]

In a stereo device capable of performing such various adjustments, a user can set an arbitrary reproduction state by operating a key or the like.However, in order to set a correction state of a frequency characteristic and a reverberation sound addition state, There has been an inconvenience requiring relatively complicated key operations.

For this reason, for example, several types of setting states are stored in advance. There is one in which the stored adjustment state can be immediately set by simply pressing a predetermined key.

However, it is preferable to set sound quality such as frequency characteristics and reverberation time for each type of music to be reproduced. That is, for example, in the case of classical music, the reverberation time is made relatively long to create the atmosphere of a concert hall, and in the case of rock music, the midrange frequencies are emphasized to give a dynamic sound. The user often changes the settings accordingly. Therefore, every time the type of music to be reproduced changes, it is necessary to perform a sound quality setting operation. Even in the case where the setting can be performed immediately as described above, it is necessary to manually change the sound quality by key operation.

It is an object of the present invention to automatically adjust the sound quality to a preset sound quality in accordance with music to be reproduced.

〔Example〕

Hereinafter, an embodiment of the reproducing apparatus of the present invention will be described with reference to the accompanying drawings.

In this example, a CD playback device incorporated in a component stereo is shown. First, FIG. 1 shows the entire configuration of the component stereo. In FIG. 1, (1) is a control unit of an amplifier device, and (2) Is the control unit of the CD player,
(3) shows a control unit of the tape deck, (4) shows a control unit of the tuner, and each of the control units (1) to (4) is composed of a microcomputer, and each of the control units (1) to (4) is connected via a bus line (5). 1) to (4) are connected. In this case, the amplifier device is provided with a function changeover (input sound changeover) switch, and the control section (1) of the amplifier device also performs function changeover control. The sound quality preset memory (1a) is connected to the control unit (1) of the amplifier device, and the sound quality set by the amplifier device is stored in this memory (1a).
Are stored so that the sound quality preset from the stored data at a predetermined time can be reproduced. That is, the amplifier device of this example includes a sound quality adjustment circuit for adjusting an equalizing level for each frequency band of an input audio signal, adding reverberation sound, and the like, in addition to an amplification circuit provided in a normal integrated amplifier. The sound quality presetting memory (1a) can store 10 sets of the adjustment states in the above by a predetermined operation. In this case, 1 to 10 for each set of adjustment data
Any command number up to is added. Then, by operating an operation key (not shown) connected to the control unit (1),
When a command number is specified, the sound quality adjustment data of the corresponding command number stored in the memory (1a) is read out, the sound quality adjustment circuit is set to the adjustment state indicated by the adjustment data, and the preset sound quality is automatically reproduced. I can do it. Also, in this example, the CD is connected via the bus line (5).
When the command number data of the sound quality adjustment data is supplied from the player to the control unit (1) of the amplifier device, the operation mode of the control unit (1) is a mode capable of automatically controlling (hereinafter, a CD link mode). At this time, the sound quality adjustment data of the command number indicated by the command number data is read from the memory (1a), and the sound quality adjustment circuit is automatically adjusted to the adjustment state indicated by the adjustment data.

A custom file memory (2a) is connected to the control section (2) of the CD player so that individual data for each disk in which the memory (2a) is set can be stored. In other words, this custom file memory (2
a) is the data of the innermost data track (hereinafter referred to as TOC track) of each disk, as shown in FIG.
Various data such as display data and sound quality data can be stored on a plurality of sheets (for example, 227 sheets). Where TOC
Explaining the track data, for example, as shown in FIG. 3, the start time (minute, second, frame number) and the total recording time (minute, second, frame number) of each music piece stored in each disk are shown. Is recorded as data. In this example, when each disc is set in this CD player, the data of this TOC track is read under the control of the control unit (2), and at a predetermined time, this data is stored in a custom file memory (2a). And sound quality data. After the data of the TOC track is once stored in the memory (2a), when the same disc is set in the CD player, the data of the TOC track is read out,
The control unit (2) determines whether or not the data matches the TOC track data stored in the custom file memory (2a). When the stored TOC track data matches the TOC track data read from the disc,
Judge that the data is stored on the disc, and
The control unit (2) reads data such as display data and sound quality data stored together with the C track data from the memory (2a), and performs control based on the read data.

In this example, display data and sound quality data are stored as custom files in the custom file memory (2a) as shown in FIG. 2 for each disk. The display data is for displaying a message on a display device (not shown) provided in the CD player, and a message such as a character or a number arbitrarily set by the user for each disc is displayed on the disc. Displayed when is set. The sound quality data is for setting the sound quality to be reproduced by the amplifier device, and the command number (any one of 1 to 10) of the sound quality data stored in the sound quality preset memory (1a) of the amplifier device described above. It is memorized. When the disc is identified by the TOC data, the sound quality data of the disc is read from the custom file memory (2a) to the control unit (2),
The control unit (2) of the CD player supplies the control unit (1) of the amplifier device via the bus line (5).

Next, the memory for the custom file of the CD player (2a)
The operation at the time of reproduction of a disc using the file will be described. First, it is necessary to store various data such as sound quality data in the custom file memory (2a). For example, when storing sound quality data, as shown in the flowchart of FIG.
Set in a CD player, read the TOC track data of this disc, determine whether the same data exists in the custom file memory (2a) (that is, whether a custom file is defined), and If the disc is not defined as a TOC track data memory (2
Perform a memory operation to a). Then, by operating a predetermined operation key of the CD player, a mode (memory mode) in which various data such as sound quality data can be stored in the memory (2a) for the custom file is set, and then preset to the amplifier device. A desired sound quality is selected from a set of reproduced sound quality by key operation. At this time, the command number data corresponding to the selected key is supplied from the control unit (2) to the custom file memory (2a), and the command number data is stored in the sound quality data recording area of the corresponding disc of the memory (2a). Remember.

When playing back a disc using the sound quality data stored in this way, first, as shown in the flowchart of FIG. 5, the disc to be played is set in the CD player. At this time, if the sound quality data of the disc is stored in the custom file memory (2a) by the above-described operation, the data of the disc is identified from the data of the TOC track, and the presence of the sound quality data is detected. When the control unit (2) of the CD player detects this sound quality data, the command number data as sound quality data is transmitted to the control unit (1) of the amplifier device via the bus line (5).

Then, when receiving the command number data from the CD player, the control unit (1) of the amplifier device determines whether or not the operation mode of the amplifier device is the CD link mode. When in the CD link mode, the sound quality adjustment data of the corresponding command number stored in the sound quality preset memory (1a) of the amplifier device is read out to the control unit (1), and the control unit (1) executes the sound quality adjustment circuit. The adjustment amount is set based on the sound quality adjustment data. Then, by starting reproduction of the disc set in the CD player by operating a predetermined key, music is reproduced with the sound quality stored in the custom file of the disc.

Further, when there is no sound quality data in the custom file or when the amplifier device is not in the CD link mode even if there is sound quality data, the reproduction is performed with the sound quality adjusted by the amplifier device.

As described above, according to the present embodiment, since the sound quality data is stored in the custom file memory (2a), the reproduction sound quality is automatically set for each disk based on the sound quality data. For this reason, for example, in the case of a disc on which classical music is recorded, the reverberation time is set to be relatively long and the sound quality that gives the atmosphere of a concert hall is set in a custom file, and in the case of a disc on which rock music is recorded, By setting the sound quality that emphasizes the mid-range frequencies to produce a dynamic sound in the custom file, the optimum playback sound quality set in the custom file is automatically set just by setting each disc . Therefore, there is no need to perform sound quality setting work every time the type of music to be reproduced changes, and the operation of the stereo apparatus is simplified.

〔The invention's effect〕

According to the present invention, the reproduction sound quality can be automatically set based on the reproduction sound quality data stored corresponding to each recording medium, and the recording medium can be adjusted without the operator adjusting the reproduction sound quality. Music and the like can be reproduced with the optimal sound quality preset for each. In the case of the present invention, when the link mode is set, automatic sound field adjustment and the like can be performed. When the link mode is not set, the desired sound can be easily adjusted based on the stored (preset) data. Place settings can be made.
