Description
Technical field
The present invention relates to be used for memory storage and recording mediums synchronously synthetic and a plurality of contents that regenerating medium writes down, particularly be used for memory storage and recording medium according to a plurality of contents of mixed information synchronously reproducing that write down.
Background technology
Except record the medium of the CD as ROM (Read OnlyMemory) (Compact Disk) etc. of music content in advance by regeneration, perhaps record on the medium of the MD (Mini Disk) that adopts magnet-optical medium etc. by music source with CD, and in the MD system, regenerate, thereby outside the music appreciating, people can also oneself play an instrument and go forward side by side line item and regenerate music appreciating.
Multiple record is the method for a kind of record and regeneration instrument playing.In multiple record, different music is recorded on each rail of the recording medium with a plurality of record rails.In other words, music is recorded on first rail in advance, and when playing and listening to this music, sound is recorded on the different rails overlappingly.For example, as at first writing down piano, when listening to the sound of this piano, write down the result of guitar then, the performance that can reset piano and guitar simultaneously.In order in the music of playing a plurality of rails, to carry out record,, need high speed, mass storage device, and hard disk mainly is used to this purpose perhaps in order to write down the music of a plurality of rails simultaneously.
Yet, because purpose is a music making, thus use the multiple record system of hard disk to need senior editing technique, and its complicated operation.Therefore, though some people uses the multiple record system that adopts hard disk, generally speaking, this system does not obtain to popularize.In addition, because the magnetic recording media of hard disk etc. does not have the such ROM portion of phase place concave point (phase pit) of CD, thus there is a problem, promptly for recording musical in advance, must therefore increase manufacturing cost for the mode recording musical of each medium with magnetic.
Also can realize adopting than the multiple record system of the more maneuverable MD of hard disk (Mini Disk) as medium.Though using the result of MD is that medium is not expensive, the user need be in a plurality of rails be the same on the recording musical this point in turn with the equipment that adopts hard disk.For recording musical information in advance before dispatching from the factory, as hard disk, need carry out magnetooptic recording, so the medium cost increases for each MD.In addition, have another problem, can recording capacity will reduce one with a plurality of rails in the corresponding amount of prerecord amount.Therefore, though some professionals use employing can write down the traditional multiple record system of MD, this system does not generally speaking obtain to popularize.
As mentioned above, except some professionals, by multiple record or the music of multiple record is carried out the method that synchronizing regeneration comes music appreciating generally speaking also do not obtain to popularize.
In recent years, concurrent ROM/RAM mode and part ROM mode are introduced into as the method with the potentiality that realize multiple record and synchronizing regeneration function at an easy rate.For example, Japanese kokai publication hei 7-65375 communique has proposed a kind ofly to record in advance under the situation of music or image information in the ROM portion that adopts the phase place concave point, synchronous different music or image information, and it is recorded in the method for the same position in the RAM portion.In addition, Japanese kokai publication hei 5-151758 communique and Te Kai flat 11-7729 communique has proposed to adopt part ROM mode and the synchronously reproducing method of the music information of record separately in time.
Yet each suggestion all relates to the method for synchronizing content in time, and not clear mixing condition when being set forth in a plurality of content of synchronizing regeneration (mixing), for example output level than or the condition of waveform characteristic.For example, when music content being carried out multiple recording and regeneration, except the time synchronized of each music content of needs, the adjusting of the mixing condition during mixing also is very crucial.Output ratio or waveform are not carried out any adjusting, then extremely unpleasant to hear to music based on the acceptable quality of mixing.
Generally because the optimum output that is difficult in when record prediction and determines each music content than or the waveform adjustment amount, so preferably after record, these projects are set freely when regenerating.In addition, must during song, change output.For example, when the multiple record guitar is played when regeneration has in advance the ROM portion of the sound of record and musical background, standard be between the song first segment and second joint, to insert an interval.In order to record loud guitar solo, and, must any time during song change mixing condition in the tranquil melody part of song other parts record in this interim.
Because will set mixed information specific to each music content, can be recorded in the independent recording medium so wish these mixed informations.In addition, this must be can be easily to be provided with according to user's preference.
In addition, as the another kind of method relevant with multiple recording, TOHKEMY 2002-171482 communique has disclosed a kind of method of carrying out multiple recording after optimal adjustment is carried out in output to voice data in advance.Yet,, realize high-quality music so be difficult in any position because must after record, utilize regenerating unit that the volume ratio is regulated again.
In addition, as the method for regulating the volume in the mixing condition, TOHKEMY 2000-173171 communique discloses a kind of method that can write down the audio volume level of each music content in TOC (Table of Contents) district.Yet, regulate because will carry out volume, so can not be with a plurality of multiple recording music contents of high-quality synchronously reproducing to each song.
