I'm certain that the "oversampling" description is just marketing
bullshit to help novices see 160 kbps as somehow more high tech or at
least obviously better than 128 kbps encoding. :-)
Newer versions of MusicMatch Jukebox use Fraunhofer (aka FhG) encoding
technology to create MP3 files. The older command line version of the
FhG encoder uses regular stereo (independent left and right channels) at
160 kbps, as does the LAME MP3 encoder. But MusicMatch uses joint
stereo (either regular or mid/side stereo) at that bitrate. Perhaps
this is what they mean by "oversampling", although that would be a
grossly inappropriate use of that term.
At 160 kbps, the FhG encoder in MusicMatch Jukebox isn't any better than
LAME. At 128 kbps, it depends on the source material. At 96 kbps or
less, FhG is better. But at 256 kbps, LAME is the clear winner.
