Editable general tone synthesis analysis system and method

Abstract

According to the editable general tone synthesis analysis system and method provided by the invention, the synthesis analysis method is used for editing and synthesizing all general or arbitrary sounds, the tones corresponding to notes with standard pitch of all traditional musical instruments can be simulated, real-time simulation is realized, a sound sample does not need to be stored in advance,and operation is simple and convenient; any known and unknown sound in the nature or imagination can be synthesized, and in addition, the various multi-level timbres can be mixed and edited to generate a new sound source. Firstly, harmonic components in a sample are analyzed, the musical sensation of the timbre of an input sound source is kept, then simulation synthesis of noise is achieved by analyzing components of non-harmonious waves, synthesis of common timbre can be achieved, and reappearance of the timbre is achieved. The synthesis analysis system comprises an audio data acquisition unit, a data processing and analysis unit, an electronic signal synthesis unit and a user interaction input unit.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an editable universal timbre synthesis analysis system and method. Background technique [0002] From the perspective of physics, sound can be interpreted as the sound wave generated by the vibration of an object, which is a fluctuating phenomenon that propagates through the medium (air or solid, liquid) and can be perceived by the auditory organs of humans or animals, while timbre generally refers to the sound except frequency and loudness. A collection of all features. As a kind of wave, timbre can be decomposed into the superposition of sine waves with different frequencies and different intensities. Therefore, the waveform is the intuitive expression of the abstract substance "timbre", and different timbres can be identified through the waveform. [0003] At all times and in all over the world, people have created a variety of acoustic instruments to show the beauty...

AI Technical Summary

Problems solved by technology

[0006] So far, there is no such thing in the prior art that can perform full-range timbre simulation reproduction of all common or arbitrary sounds (not limited to timbres corresponding to notes of all pitches of traditional musical instruments, and can be simulated in real time without pre-stored sounds. sample), and the system and method that can mix and edit the above-mentioned multiple multi-level full-range universal timbres to generate new sound sources
