APP can carry out preview to elementary audio file；
S3, other musical instrument types are selected by step S2, and forms other instrumental audio files and is temporarily stored in audio DSP module；
S4, user input the lyrics to synthesis DSP module by cell phone application, and user is selected out of storage server by cell phone application
Suitable voice channel, synthesis DSP module transfer the voice channel of selection, and synthesis DSP module carries out the synthesis of voice according to music score,
Voice audio file is formed, voice audio file is temporarily stored in audio DSP module；
S5, user issue the instruction for synthesizing final audio file by cell phone application to synthesis DSP module, and synthesis DSP module is transferred
Elementary audio file, other instrumental audio files, voice audio file are finally synthesized, and form final audio file, finally
For audio files storage in audio DSP module, user carries out preview by cell phone application, if meeting the requirements, elementary audio file,
Other instrumental audio files, voice audio file, final audio file unloading enter storage server, user by cell phone application from
Elementary audio file, other instrumental audio files, voice audio file, final audio file are downloaded in storage server.
Preferably, the login service device is for creating user, modification user, deleting user and user's login.
