BSS Locate

A toolbox for source localization in stereo convolutive audio mixtures


by C. Blandin, E. Vincent and A. Ozerov


Purpose

BSS Locate is a Matlab toolbox to estimate the Time Differences of Arrival (TDOAs) of multiple sources in a stereo audio signal recorded by a pair of omnidirectional microphones. The number of sources and the distance between the two microphones are assumed to be known but are not restricted to a given range.

BSS Locate implements 12 different source localization methods:

GCC-NONLIN provides the best results over a wide range of configurations.

Multi-Channel BSS Locate

A toolbox for source localization in multi-channel convolutive audio mixtures


implemented by R. Lebarbenchon and E. Camberlein


Purpose

Multi-Channel BSS Locate is a Matlab toolbox to estimate Direction Of Arrival (expressed both in azimuth and elevation) of multiple sources in a multi-channel audio signal recorded by an array of microphones. This toolbox implements the previous 8 angular spectrum methods presented in BSS Locate.
