Claim Text:
1. A method for processing source signals, comprising the steps of: emitted, by a set of sources at different locations in a reverberant environment, the source signals, wherein the source signals are acoustic signals; acquiring, using a set of sensors, input signals corresponding to the source signals, wherein the sensors are microphones and the input signal at each frequency is modeled as a linear combination of all the source signals at that particular frequency, and wherein coefficients in the linear combination correspond to a frequency response of the environment from each location at that frequency; and applying a sparsity-based support estimation to the input signals according to a reverberation model to produce estimates of the source signals and the different locations of the set of sources, wherein the applying is performed in a processor.
