I recently read that the TIDUS method can sound unnatural and that using reverbs (whatever that is) should sound better. Could you point me to a guide on how to use reverbs to make a stereo file out of a mono one using Audacity?
By adding a bit of stereo reverb a mono recording can get some width, spaciousness and sound more pleasant. It all depends on the purpose and the context of the recording and you simply have to experiment. You should definitely have a look at Impulse Response (IR) plugins and applications. They can give great results, depending on the quality of the IR sample.
I'm currently working on the audio for a music documentary dvd. Some of the audio is in mono and, when used right after a stereo or even a surround recording, the sound image will collapse. It is likely that reviewers will complain about that.
IMO adding a bit of stereo "sauce" won't harm. It will be fake, but then . . . . welcome to the world of music recording
