Audio synthesis system based on different types of audio data

Abstract

The invention refers to acoustic frequency synthesizing field, which discloses a kind of acoustic synthesizing system based on different kinds of acoustic data, it includes an analyzing subsystem an and a synthesizing subsystem B; the analyzing subsystem includes an acoustic file analyzing model and an acoustic synthesizing event generating model; the synthesizing subsystem B includes an event dispatching control model, an acoustic synthesizing model and an acoustic data area stored with the acoustic needed by acoustic synthesis; the invention is a kind of acoustic synthesizing system which can synthesize and reappear different kinds of acoustic data files, the two parts are independent.

Description

technical field [0001] The present invention relates to the field of audio synthesis, in particular to a sound synthesis system for synthesizing and reproducing different kinds of sound data files transmitted by using a sound source database provided by the system. Background technique [0002] The sound files restored and reproduced by the sound synthesis system in the prior art mainly include the following three categories: [0003] 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 waveform data. MP3 is such a file, as attached figure 1 As shown, when synthesizing sound, the MP3 decoder decodes the MP3 data and restores it to PCM sound waveform data. If you need to change the sound waveform characteristics, such as: sa...

Problems solved by technology

[0006] Since the sound signal file contains sound waveform data, the file size is relatively very large, so it is not suitable for application in many cases. For example, the sound synthesis part in mobile phones usually uses music score type files and speech synthesis files. In practical applications, there are different types of music score files, and the support for different types of files is a problem. In addition, it is usually more difficult to require the sound synthesis system to support both file formats of music score files and speech synthesis files. The common solution The method is to use different independent systems to process these two file formats separately. The disadvantage of this is that not only the system is complicated and the structure is huge, but the solution is not compact enough. In addition, an additional system is needed to coordinate the work of different synthesis systems, which is undoubtedly uneconomical. of
