Music file forming device, music file forming method and recording medium

Abstract

A singing voice extraction section 2 that extracts human singing voices from the digital sound generator data 11 and obtains the signing voice data 12 in the ADPCM format, the BGM generating section 13 that generates the BGM data 13 in the MIDI format, the MIDI adjustment section 4 that generates simulated singing voice data in the MIDI format based on the extracted signing voices and adds such data to the BGM data 13, and the file generating section 5 that processes the singing voice data 12 and the BGM and simulated singing voice data 14 into a single music file 15 are established. Bandwidth limiting is significantly executed for the singing voice portion. Through generating the BGM portion in the MIDI format, the entire amount of data is decreased, and the singing voice portion that has been deteriorated in quality due to the performance of bandwidth limiting is supplemented by MIDI data. Due to this, the quality of the reproduced singing voices can be also maintained beyond a predominating level.

Description

technical field [0001] The present invention relates to a music file generating device, a music file generating method and a recording medium of a music file with a specific data structure, in particular to a music file synthesized from human singing and BGM and the data structure of the music file. Background technique [0002] Nowadays, with the rapid popularization of mobile phones, mobile phones have become a kind of machine that everyone must carry with them. In the original mobile phones, the ring tone of an incoming call was just a repetition of a very monotonous pattern tone. soon. In order to adapt to more personalized market demands, chords made of MIDI (Music Instrument Digital Interface: electronic musical instrument digital interface) data have begun to be used as ringtones for incoming calls, so-called "chords for incoming calls". [0003] Furthermore, a mobile phone with a built-in PCM sound source appeared several years ago. Using this PCM sound source, an ...

AI Technical Summary

Problems solved by technology

Even if the intercepted data is compressed in the form of MP3, the small-capacity memory of existing mobile phones cannot be used

Have again, although existing mobile phone has the playback function of MIDI sound source and PCM sound source, does not have the playback function of the data of MP3 form

[0007] The above shows that in the existing singing voice system for incoming calls, there is a problem that if it is not a new model that holds a very large memory and includes a decoder in the form of MP3, it will not be possible to use this service
