Audio file generation method, device and digital player

Abstract

This invention is applicable for information technology field, it provides a kind of audio frequency producing method, device and number player, this method includes the following steps: read the preset former sound audio frequency data which is in the same size of the former sound audio frequency block from the former sound audio frequency data, and read it in the audio frequency file; read the preset accompanying sound audio frequency data which is in the same size of the accompanying sound audio frequency block from the accompanying sound audio frequency data, and read it in the audio frequency file, the play time of the former sound block audio frequency data and the accompanying sound audio frequency data is the same; cycle executes the steps mentioned above, until both the former sound block audio frequency data and the accompanying sound audio frequency data are read in the audio frequency file which containing data from two tracks. In the implement case of this invention, to realize the image and void accompany function of the number player by producing a kind of audio frequency file storied the former sound block audio frequency data and the accompanying sound audio frequency data alternately, so it has good image and void accompany effect.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method and device for generating audio files and a digital player with audio-visual accompaniment and singing functions. Background technique [0002] At present, audio-visual accompaniment (karaoke) has become one of the important activities for users' entertainment and leisure, and various audio-visual accompaniment machines and household appliances with audio-visual accompaniment functions have appeared. The audio-visual accompaniment electro-acoustic technology and products are relatively mature, but most of them are designed for fixed use in families or entertainment places. Small size, easy to carry. [0003] In the prior art, the audio-visual accompaniment function of the digital player is realized by eliminating the sound data in the original singing audio data, and aliasing the audio data with the removed sound data and the sound data input by the use...
