Abstract

The invention relates to a synchronous accompaniment audio file manufacture method of music and a synchronous accompaniment MP3 player matched with the method. The invention is mainly characterized in that the player can simultaneously play songs and realize the accompaniment effect, and can display synchronous song lyrics. The invention adopts the modern advanced digital audio technology, a multitrack surround system and the advanced digital coding/decoding technology to manufacture synchronous accompaniment audio files for songs, and uses song lyric editing software to edit the synchronous song lyrics for the synchronous accompaniment audio files. The synchronous accompaniment MP3 player adds a set of identical sound-replaying systems (comprising a D/A converter, an amplifier, a built-in loudspeaker or an earphone output port and the like) on the basis of the original MP3 player. An accompaniment-replaying system and a song-replaying system are independent without mutual interference, are respectively provided with switches for independent control, can be respectively turned on for independent playing, and can also be simultaneously opened for simultaneous playing. The synchronous accompaniment MP3 player can only play songs to be used as an MP3, can also only play accompaniment, and can simultaneously play the songs and the accompaniment to make users enjoy the happiness like KTV. A computer manufactures and stores the synchronous accompaniment audio files, and the synchronous accompaniment MP3 player downloads and plays corresponding audio files. The synchronous accompaniment MP3 player has the advantages of small size, light weight, portability and market prospects.

Description

Synchronous accompaniment audio file manufacture method and synchronous accompaniment MP 3 player

Technical field:

The present invention relates to a kind of synchronous accompaniment audio file manufacture method and a kind of synchronous accompaniment MP 3 player that matches with it of song, mainly is to play function played songs and accompaniment simultaneously, and the display synchronization lyrics.

Background technology:

Karaoke or KTV make the ordinary people no matter be that nightingle throat or drake larynx have all crossed one singer's addiction, the disposition that keeps one's own counsel inadvertently smooth dew in the fighting for of microphone comes, the pressure that does not have specialty performance, listen attentively to sing in exchange, realized self-selection and common participation enjoyment.

Flexible and the degree of freedom of MP3 or MP4 walkman makes us listen attentively to song more easily, and enjoy music brings people's fast happy glamour.

Modern advanced multimedia equipment allows the easier singing of people and listen song, but this also is difficult to satisfy people's needs.If we can enjoy whenever and wherever possible as sing elegant one the KTV place.Certainly we also can use computer and sound equipment, just carry inconvenience.We have designed a kind of player---synchronous accompaniment MP 3 player, and it is played songs and accompaniment simultaneously, and the display synchronization lyrics.Red-letter day such as young man's party, birthday Party, August 15, New Year's Day, classmates opened a little party, open-air rally amusement, and we can use these occasions this sample to invent to sing song and increase happy atmosphere.

Summary of the invention:

In order to provide accompaniment whenever and wherever possible, sing song, we have designed a kind of synchronous accompaniment MP 3 player, its played songs and accompaniment simultaneously, the display synchronization lyrics.Use this player, we can listen song by wearing headphones, see the synchronized lyrics of demonstration, put outside under the situation of accompaniment, sing, and avoided not catching up with accompaniment, have forgotten the awkward problem of the lyrics, to the greatest extent can be relieved sing to everybody.

The present invention relates to a kind of synchronous accompaniment audio file manufacture method and a kind of synchronous accompaniment MP 3 player that matches with it of song, mainly is this broadcast function played songs and accompaniment simultaneously, and the display synchronization lyrics.We adopt modern advanced digital audio technology, and multichannel surrounding system and advanced numerical coding/decoding technique come to make synchronous accompaniment audio file to song, and use lyrics software for editing to give synchronous accompaniment music file editor synchronized lyrics.Synchronous accompaniment MP 3 player of the present invention has increased the same sound-reproducing system (comprising D/A converter, amplifier, boombox or earphone delivery outlet etc.) of a cover on the basis of original MP3 player.Accompaniment playback system and playback of songs system are independently non-interfering, are respectively equipped with switch and control respectively, open respectively respectively and play, open simultaneously simultaneously and play, the song of promptly can only singing is made MP3 and is used, and also can only put accompaniment, and it is happy that broadcast simultaneously can be enjoyed similar KTV.Computer photograph synchronous accompaniment music file also stores the supporting use of synchronous accompaniment MP 3 player file in download.

Fig. 1 is the synoptic diagram of synchronous accompaniment audio file making and music playback embodiment 1

Fig. 2 is the synoptic diagram of synchronous accompaniment audio file making and music playback embodiment 2

Fig. 3 is the workflow diagram of synchronous accompaniment MP 3 player

Embodiment:

1. synchronous accompaniment audio file is made and music playback embodiment 1: the sound signal of recording or gathering the accompaniment of (audio material) and song is delivered to respectively in two sound channels (sound channel A1, sound channel B1) disposal system and is carried out signal Processing, encode then, store, transmit, be made into music file; Download playback time and signal is reduced to two non-interfering independent signals of coding, after amplifying, be input to respectively in two loudspeakers, play out accompaniment and song respectively and simultaneously by demoder.

2. synchronous accompaniment audio file is made and music playback embodiment 2: the accompaniment audio signal of recording or gathering (audio material) is carried out stereophony (L channel A respectively, R channel A) signal Processing, the song audio signal of recording and gathering is also carried out stereophony (L channel B respectively, R channel B) signal Processing, then, scrambler synthesizes two sound channels by the channel combinations function with the quadraphonic, be about to original L channel A, R channel A, L channel B, 4 signal encoding Synthetic 2s sound channel (sound channel A2 of R channel B, sound channel B2) Composite Double sound channel signal, store then, transmission is made into music file; The Composite Double sound channel signal that the download playback time will encode by demoder is sound channel A2, sound channel B2 signal, L channel A, R channel A when being reduced to coding, 4 non-interfering independent signals of L channel B, R channel B are input to playing back music in 4 loudspeakers respectively after amplifying.

3. the synchronous accompaniment audio file of making among the embodiment 1,2 is edited synchronized lyrics with lyrics software for editing again.

4. synchronous accompaniment MP 3 player: synchronous accompaniment MP 3 player of the present invention has increased the same sound-reproducing system (comprising D/A converter, amplifier, boombox or earphone delivery outlet etc.) of a cover on the basis of original MP3 player.Accompaniment playback system and playback of songs system are independently non-interfering, are respectively equipped with switch and control respectively, open respectively respectively and play, open simultaneously simultaneously and play, the song of promptly can only singing is made MP3 and is used, and also can only put accompaniment, and it is happy that broadcast simultaneously can be enjoyed KTV.

Synchronous accompaniment MP 3 player workflow: at first the synchronous accompaniment music file is taken out and reads digital signal on the storer → and signal is decoded restore non-interfering independent signal → convert simulating signal → to from internal memory to again the analogue audio frequency after the conversion being amplified → be input to respectively after the low-pass filtering boombox or the earphone delivery outlet of accompaniment and song respectively to the digital signal of decoding being come out by D/A to decoding chip.
