ニューラルネットワークによる管楽器音の識別

概要

It is difficult to identify musical instruments only by hearing their tones, especially in the following cases : (1) Their timbre are similar. (2) Their pitches are the same. (3) The length of the notes played is short. We are developing a wind instruments tone-identification system which can work even in the above mentioned cases. In this system, the instrumental tones are analyzed by LPC (Linear Predictive Coding), the frequency spectrum is detected, and the type of instrument is determined by using neural networks. This system is able to identify wind instruments better than human beings can.
