Abstract

The paper presents a prototype of a portable PC-based system, called MusicEar, able to perform real time analysis, archiving and visualization of violin sound and thus support violin sound quality assessment. MusicEar visualizes the frequency spectrum in different scales including the Duennwald frequency regions designated specially for timbre characteristics of violins. It also calculates the instantaneous parameters based on Long Term Averaged Spectrum (LTAS) and stores them in a database. It enables comparison of characteristics of instruments sound already saved in the database.
