I've found the solution using [soundfiler].
If you know other way, please let me know.

Hello list,

do you know some way to read a soundfile (.wav, 2 channels) from the end to the
beggining without convert the file? 

I'm trying to make a "mirror". I write any sound (variable longitude) to a wav file,  and
when a stop the recording, it must be played reverse.

Any help will be appreciated. Thanks.
