The quality is the same for stereo and mono. If you input files are stereophonically recorded, and actually contain two channels of speech, choosing mono output in lame will convert the monophonic sound. (This is the same whether you use lame or any other mp3 encoder.) > * Does stereo mean output in two speakers and mono > mean output in one speaker ? No, both stereo and mono means output in two speakers. (For output in only one speaker, you would need a stereo file where one channel is silent.) Mono means the same output in both speakers. (Again, this is the same whichever mp3 encoder you use.) > * When I play a mono wav file in the computer, in both > the speakers sound is heard.

Monophonic mp3 files play the same sound in both speakers (see above). > If I encode to mp3 as mono what will be the loss in > quality of output to listener ? Nothing. The only loss will be that the sound is monophonic. If I understand you correctly, you have a stereo speech recording, and you want to convert it to mp3 for CD distribution. If so, the choice of stereo or mono is unrelated to the mp3 encoding process and the mp3 output files. Converting the wav file to mono or converting the mp3 file to mono will have the same effect on the sound. So this is more of a general audio issue, but if the only purpose of the recording is to convey the contents of the lectures, I don't see any reason why stereophonic sound would be needed. My recommendation for your lecture files would be 22 kHz, VBR and mono. (I would recommend the speech preset in lame, but I have no experience with it. Anyone?) _______________________________________________ mp3encoder mailing list [EMAIL PROTECTED] http://minnie.tuhs.org/mailman/listinfo/mp3encoder
