Problems solved by technology

In this way, when performing sound synthesis, usually only one sound file or piece of music can be played at a time, but two sounds cannot be played or synthesized at the same time. For example, when a piece of music is playing normally, it cannot Insert other instant playing sounds; or, when a background music is playing, we can not play the key sound

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0039] As shown in Figure 2, it is an embodiment of the device of the present invention. include:

[0040] Sound event buffer 1 and a sound event interpreter 1, a sound file is converted into a specific coded sound event 1 through specific software, this sound event data will be sequentially put into the sound event buffer 1, sound event interpretation Device 1 reads sound event data from sound event buffer 1, and interprets these data to generate interpretation data;

[0041] A sound event buffer 2 and a sound event interpreter 2, another sound file is also converted into a specific coded sound event 2, and this sound event data is finally converted into another set of interpretation data;

[0042] The above two sets of interpretation data will be se...

Abstract

This invention discloses an audio sequence device including a set of voice process device composed of a voice event buffer and a voice event analyzer characterizing in also including a control device and a set or many sets of voice process devices, each set includes a sound event buffer and a sound event analyzer. This invention also discloses a voice document process method, which can support multiple voice documents to be played at the same time.

Description

technical field [0001] The invention relates to the field of sound synthesis, in particular to an audio sequencer in a sound synthesis system and a sound file processing method thereof. Background technique [0002] In the prior art, sound files are generally restored and reproduced through a sound synthesis system. [0003] Sound files mainly include the following three categories: [0004] Sound signal files, this type of file basically records the waveform data of the sound itself, and uses different encoding algorithms to process the original waveform data to reduce the file size. When restoring such sound files, use the corresponding decoding Converter to restore it to the original sound wave data, MP3 is such a file; [0005] Music score files, which record the rhythm and scale information played by musical instruments, do not themselves contain specific sound waveform data. Therefore, the characteristic of the score file is that the file size is very small, and a l...
