Real-time Timbre Analysis and Synthesis

  Tristan Jehan

A synthesis engine that predicts the timbre of arbitrary acoustic instruments. Musically meaningful, it is controlled by the perceptual features extracted from the audio stream of an acoustic or electric violin in real-time. The timbre models are built from the analysis of pitch, loudness, brightness and the instantaneous power spectrum of real recordings. Although highly compressed, the sound quality is fully preserved. Also the playability remains smooth, expressive, predictable and is adequate for sound morphing.
