SBM: Matlab toolbox for Supervised Binaural Mapping

The SBM Matlab toolbox for “Supervised Binaural Mapping”, contains a set of functions and scripts for supervised binaural sound source separation and localization. The approach consists in learning the acoustic space of a system using a set of white-noise measurements. Once the acoustic space is learned, it can be used to efficiently localize one or several natural sound sources such as speech, and to separate their signals.

This toolbox include:

  • The algorithm Probabilsitic Piecewise Affine Mapping (PPAM) published in [1]
  • The algorithm Variational EM for Sound Source Separation and Localization (VESSL) published in [2,3]
  • 7 usage examples demonstrating single and multiple sound source localization, sound source separation, and online audio-to-video mapping

This toolbox requires:
