Online Multiple Sound-Source Localization

Keywords: Audio signal processing - Multiple sound-source localization - Matlab - Direct-path RTF

Functional Description: This project tackles multiple sound-source localization in noisy and reverberant environments, using binaural recordings of an acoustic scene. It provides Matlab routines to estimate multiple sound source (such as speakers) locations based on direct-path relative transfer function (DP-RTF) estimation.
