Embodiment Construction

[0022] Various embodiments of the accompaniment / original audio data switching method and system of the present invention will be described in detail below.

[0023] Such as figure 1 As shown, it is a schematic flow chart of one embodiment of the accompaniment / original audio data switching method of the present invention, including steps:

[0024] Step S101: Acquiring monophonic original singing audio files and monophonic accompaniment audio files and their corresponding audio formats;

[0025] The purpose of this step is to obtain the monophonic file of the original singing and the monophonic file of the accompaniment and their corresponding audio formats.

[0026] The stored original singing file and accompaniment file are not necessarily monophonic, and then need to be converted into a monophonic file, that is, before step S101, it may also include:

[0027] Save the original singing audio data and the accompaniment audio data as the original singing file and the accompani...

Abstract

The invention discloses a method and system for switching accompaniment / original audio data. The method includes the steps that original audio files of a single track, accompaniment audio files of the single track and audio formats of the original audio files and the accompaniment audio files are obtained; the original audio files and the accompaniment audio files are arranged alternately according to the audio formats and are combined into dual-track audio files; the mode of coding through dual tracks is used for coding the dual-track audio files, and coded files are obtained; the coded files are sent to a client side which is used for decoding, switching and playing the coded files. According to the scheme, the mode of independent coding with the dual tracks is used for coding the dual-track audio files, and aliasing of the accompaniment audio data and the original audio data can be avoided. Due to the fact that the accompaniment audio data and the original audio data can be played only by sending one file to the client side, the requirement for the bandwidth is low, and therefore transmission efficiency is improved. In addition, only one part of data need to be decoded at the client side, and playing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an accompaniment / original singing audio data switching method and system. 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 playback devices with audio-visual accompaniment functions have appeared. [0003] In order to realize accompaniment / original singing switching, the prior art stores the original singing audio data in an audio file, and stores the accompaniment audio data in an audio file. Through the mutual switching of the two files, the switching between the accompaniment and the original singing is realized. [0004] The above method generally generates two files in the server, and then transmits them to the client separately. Since the simultaneous transmission of two files requires a large bandwidth,...
