Detailed Description

Azimuth Discrimination and Resynthesis (ADRess) - sound source separation.

ADRess takes a stereo input (i.e. input is expected to be the output of a parallel of two Spectrum MarSystems, one for each stereo channel), and outputs the phase vector and frequency dependent nulls matrix for each channel using the following format:

[bin_phases_l][AZl] [bin_phases_r][AZr]

This algorithm was proposed by Dan Barry et al at the DAfX04, "Sound Source Separation: azimuth discrimination and resynthesis". The algorithm exploits the use of pan pot as a means to achieve image localisation within stereophonic recordings, assuming only an interaural intensity difference exists between left and right channels for a single source. A gain scaling and phase cancellation technique is then used to expose frequency dependent nulls across the azimuth domain, from which source separation and resynthesis may be carried out.
