Resampling and downmixing from/to stdin/stdout

[nonoitall]

Are there any command line applications out there that can resample and/or downmix (stereo->mono) a plain old PCM wave file to another plain old PCM wave file through stdin and stdout? I've Googled up a storm, but the only thing I can find that's even remotely close is LAME, which outputs an MP3 file rather than PCM. I don't care if one program does resampling and another does downmixing, so long as I can pipe them together with other programs through the standard I/O streams. Thanks in advance!

You might check out the free software packages described in this thread (http://forum.doom9.org/showthread.php?t=82755&highlight=McGill).

Neat! The tools here (http://www-mmsp.ece.mcgill.ca/Documents/Software/index.html) look like exactly what I need. Thanks!

I'm glad it worked out for you. I've used these McGill programs before and they work very well.

To late but CopyAudio.exe can be used, instead WaveWizard, to encode directly to ac3 your stereo outputs:
CopyAudio -S "FL FR FC LF BL BR" FLFR.wav CLFE.wav SLSR.wav - | aften - out.ac3

That's what I'm using. :)
