Check out our work on Auditory Model inversion. The paper is available on my web page at The work was presented at ICASSP in 1992. The work I did went all the way through the cochlear model, to a correlogram and then back to audio. The result was nearly indistinguishable from the original sound. The techniques are the same for a gammatone filter. Other work in the area was also done by Yang and Shamma (who showed me the filter-bank inversion technique) and many others. Some of the references can be found in my paper. -- Malcolm
