Very simple task. First I read the lame(1) manual carefully, and decide it cannot help. I tried to install several sound editor, glame tried to pull down the gtk1 library and depended packages, so stopped it. audacity takes too long time to compile (still doing now). I tried sweep, and it hung my machine; it seems trying to load the whole wave file into memory. I find xwava compiles correctly, runs okay, but it can do downmix "only when the file fits memory". I also tried several other ports I don't remember now. Now I worked the whole afternoon without any progress. I think there must be some handy tools can do this. On audio port directory I tried make search key=mono make search key=downmix Both returned nothing. So what do you suggest me to use? If this happens to be your situation, dudes, how do you find a handy tool quickly? I don't want to waste time on such jobs in future again. _________________________________________________________________ Ãâ·ÑÏÂÔØ MSN Explorer: http://explorer.msn.com/lccn/
