I remember reading a posting on the comp.dsp newsgroup about this sort of
problem, recommending that the gain be made ~very~ slightly greater than unity,
and the output is clipped. Might that work here?

Illegal Art (http://www.detritus.net/illegalart/) invites all audio
artists to contribute to the second Illegal Art project, tentatively
called Extracted Celluloid.  For this project only sounds and music from
films may be used in the assemblage of tracks of any style or genre.  

The last project, Deconstructing Beck, ended up being sponsored by rtmark
(http://www.paranoia.com/~rtmark) and received quite a bit of attention in
the media.  It is still available from Illegal Art via mail order and is
in the process of being co-released by Seeland Records
(http://www.negativland.com/nmol/seeland.html).  

We hope that Extracted Celluloid will be just as successful and rtmark and
Seeland Records have already expressed interest in possibly supporting the
release (if it meets their standards).  We also hope that we will be able
to give artists whose tracks are selected some sort of compensation.  If
you are interested in participating in this or other Illegal Art projects
please contact us at illegalart@detritus.net for deadlines and further
details

Feel free to pass this invitation along!
