Hello Dick!Kind regards,
I am not sure if this is what you are looking for, however I am using a simple precedence effect in my 'machine hearing' model for speaker localization by subtracting a time-shifted average from the signal in each band, as introduced in:
Plinge, A., Hennecke, M. H., & Fink, G. A. "Robust Neuro-Fuzzy Speaker Localization Using a Circular Microphone Array", in 12th International Workshop on Acoustic Echo and Noise Control; Tel Aviv, Israel, 2010 http://patrec.cs.tu-dortmund.de//pubs/abstracts/Plinge2010-RNF.htm
A similar idea was used in:
K. J. Palomäki, G. J. Brown, and D. L.Wang, “A binaural processor for missing data speech recognition in the presence of noise and small-room reverberation,” in Speech Communication, 2004, vol. 43 (4), pp. 273–398.
