The ATRIM project aims to develop high precision real time pitch and timbre analysis for musical wind instruments. The approach is to design and explore reactive visual renderings of the sounds produced by musicians, in forms that provide an accurate and informative real-time feedback during musical performance.

A first objective is to develop reliable tools for musician testers at the end of the production cycle of musical instruments.

A second objective is design visual feedback to help musicians adjust their motor control to their own targets or intonation, vibrato, glissando, timbre or playing effects.

To this end, the main work is devoted to elaborate new indicators and visual renderings built on some accurate spectral estimates used in the Snail-Analyser, together with graphical interfaces designed in collaboration with expert musicians.
