Juanjo Burred, researcher from IRCAM, will give a seminar on "Supervised Musical Source Separation from Mono and Stereo Mixtures based on Sinusoidal Modeling" on Tuesday July 22nd at 12:30 in room 301 of Ocata.

Abstract: The talk addresses the separation of single-channel and two-channel mixtures of musical instruments, partially relying on a timbre modeling method that delivers a set of compact templates describing the dynamic behavior of the spectral envelope. Detected sinusoidal tracks are grouped according to common-fate and continuation cues validated by using the templates as reference. For stereo separation, this principle is combined by a previous stage of blind source separation based on l1-norm minimization and exploiting spatial diversity. The timbre modeling stage can furthermore be used for other content retrieval applications such as musical instrument classification and polyphonic instrument detection.
