The "final mix" might, in some cases, might actually be in Mono. shocked



"Finally, where high levels of data reduction are required, a similar approach is taken to stereo. The source signal is matrixed from conventional left/right stereo into Middle and Sides channels, and the Sides information is discarded or drastically data-reduced. Some stereo information is then reconstructed at the decoding stage, but at very low bit rates listeners can find themselves hearing the music in mono."
