Is there a way to get the sound out of a movie clip? What program would I use?

You would need a demultiplexer. Which one depends on what kind of movie file you’re working with. Is it an mpeg-1? mpeg-2? avi? windows media? quicktime? real?

Right off the top of my head

for mpegs (1 and 2)
you can use tmpgenc (you can get it at tmpgenc.net), go to file, then choose mpeg tools, then choose the SIMPLE demultiplex tab. Browse for your input file and click run.

for avis
you can use virtualdub (you can get it at virtualdub.org), open your file, then go to file, and click save wav.

for windows media files (.wmv, .asf)
you can use asftools (you can get it at geocities.com/myasftools). Click add and open your file. Then click convert. Then click convert to wav. And then click convert again.

for quicktime movies
you can use quicktime pro. Open your file, then click file and choose export. Next to Export on the drop-down menu choose Sound to WAV (or to whatever other format you want to convert it to). Then set your options like sampling rate, bitrate, etc. then click save. Note that this may recompress the audio stream if you choose a format other than uncompressed wav (in which case the output file may be huge). I don’t know of any means to losslessly extract the audio stream. Ask around in the board, someone may know.
