Design of Piano Timbre Recognition System Based on Computer Technology

A set of piano tone recognition and electronic synthesis system suitable for modern Musical Instruments was established to better apply computer technology to the music industry. Firstly, the sound quality characteristic model of music works based on digital identification is proposed, and the overall structure and function of the system are analyzed. The sound quality identification and electronic synthesis system of piano are studied by using Boriet analysis. First of all, it must solve the problem of sound quality identification. Secondly, it uses digital identification technology to extract the multiplication points of piano sound from the characteristic matrix of piano sound color. In this way, the envelope which can reflect the evolution law of sound intensity with time is extracted, so as to improve the recognition effect of piano sound quality. Through the experimental and theoretical research, it is proved that the method can achieve high accuracy and SNR in the range of 600~2100 Hz. The correct recognition rate of sound shows that the system has good perfection.
