Too much switching between mid/side and regular 1198159b3361Sopenharmony_ci stereo can also sound bad. To determine when to switch to mid/side 1199159b3361Sopenharmony_ci stereo, LAME uses a much more sophisticated algorithm than the one 1200159b3361Sopenharmony_ci described in the ISO documentation. 1201159b3361Sopenharmony_ci </p> 1202159b3361Sopenharmony_ci <p> 1203159b3361Sopenharmony_ci FORCED MID/SIDE STEREO forces all frames to be encoded with mid/side stereo.

But it is useful for creating low bitrate 1221159b3361Sopenharmony_ci mp3s from high bitrate mp3s. If the filename ends in ".mp3" LAME will assume 1222159b3361Sopenharmony_ci it is an MP3.
