Converting mp3 stereo to mono (lossless)

I have a bunch of recordings that are mono by nature (speech), but have been encoded in forced stereo (not j-stereo) mode. The uncompressed versions no longer exist, so proper encoding from scratch is not possible.

Is there a tool for extracting one channel of these files and saving it as mono mp3s, without re-encoding?

What you are asking is probably possible, but it is a lot of work just to make the files somewhat smaller. Unfortunately, the quality that was lost by using forced stereo can never be recovered.

Yes, file size optimization is what I'm looking for. 50% is a lot when you talk about large quantities. So basically nobody's ever done anything like that before because there's no demand?

I contacted the creator of mp3DirectCut and he also thought that it would be possible theoretically, but difficult to implement. So I guess I'm on my own here and have to program it myself. Thanks anyway.
