Well, I searched a little for an audio editing tool and came across
mp3DirectCut. Well, okay, I admit, I didn't really look that hard. This is actually the first one I tried. But it looks okay.
Plusses:<ul type=square><li>It's freeware.
<li>It's small. The executable is only 40k.
<li>It doesn't require installation. Just unzip it and click on the executable.
<li>It doesn't decode and re-encode the files. It just edits them as mp3s. This make the cutting process very fast. Just highlight a 30-second selection, go to the file menu and select "save selection", and you're done. It's nearly instantanous.
</ul>Minuses:<ul type=square><li>Will people actually download a program in order to make a clip? Well, I'm a Cellar addict, so I know I would.
<li>It's Windows-only (I'm sure Linux and Mac users are smart enough to figure something out for themselves).
<li>Still bandwidth-intensive if the Cellar hosts the files. I made a 30-second clip of a 128kbps mp3 and it came out to 470k.
