Gammatone analysis/synthesis

[Joe Pompei <pompei@xxxxxxxxxxxxxxxxxxx>]

        Greetings,

        Has anyone here experimented with resynthesizing audio signals after
they have been decomposed with gammatone filters?

        The gammatone 'transform' is in no way orthogonal or easily invertible
(like wavelets), but perhaps by using discrete frequencies, experimenting with
the filter length, or using other tricks resynthesis can be done with minimal
error.  Anyone have experience with this?  All of the gammatone references I
have explore analysis only.

        Thanks,
