I haven't tried the software decoders so I can't comment on them (I'm an
analog guy). The early versions of Adobe Audition had some built-in
decoders but I think that stopped with Version 3. It makes sense that
software would work well, especially for SQ because of the ability to
filter out the carrier in the digital domain used by SQ. Tracking a
phase encoded signal (QS) that was encoded in the analog domain may be a
different story. Using software to decode the stereo analog sound track
on motion picture film (Dolby encoded) may give us the answer to the QS
question.

Cheers,
