A probability model for interaural phase difference
We propose a number of cues and a strategy for combining them that could be used by a binaural machine to perform source separation. Our previous work has used the single cue of interaural phase difference (IPD) to segment the time-frequency plane using an EM algorithm. We see this as a first step towards a larger and more complete system that takes advantage of more of the cues available to a listener from the stereo mixture such as interaural level difference (ILD), monaural cues, and reliability cues. Additionally, these cues could be integrated with one another by extending the existing probabilistic framework.
