Piece of cake!
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.
