Re: Precedence effect in real systems?



Dear Dick,

Not directly related to source separation as you queried in your original message, but these may be also be of interest nonetheless: 

1) I used a simple statistical model of the precedence effect as part of my PhD in 2004. The statistical model was published in AAuA in 2006:

Hacihabiboglu, H., and Murtagh, F., (2006), "An observational study of the precedence effect", Acta Acustica united with Acustica, 90(3), pp. 440-456, May/June 2006.

We have later used that model to simplify ISM-based binaural room auralization by a perceptually informed clustering of image sources:

Hacihabiboglu, H., and Murtagh, F., (2008), "Perceptual simplification for model-based binaural room auralisation", Applied Acoustics, 69(8), pp. 715-727, August 2008.

2) In an earlier work published in IEEE WASPAA in 2003 I used onset dominance to reduce the complexity of the binaural synthesis of early reflections. A graceful degradation approach was used to keep the filter size fixed while processing not only the direct sound but also the reflections.

Hacihabiboglu H., (2003) “A fixed-cost variable-length auralization filter model utilizing the precedence effect”, Proc. IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA-03), pp. 1-4, New York, USA, 19-22 October, 2003.

I hope that these are also relevant.

Best,

Hüseyin
