Re: Filter PET scanner noise (fwd)

[flatmax <flatmax@xxxxxxxxxxxxxxx>]

Assuming this is software based speech enhancement, you might want to try
the follwing link:
http://harduf.technion.ac.il/flatmax

It has software which works (with a small ammount o modification) under
octave (http://www.octave.org), originaly made with Matlab however (Linux
OS).
