True, but why are we generally obsessed with carrier leak (or a lack of it) on
SSB signals?
A bit of leak, say 20-30dB below peak, would allow for synchronous detectors
and frequency tracking of drifting signals
by the radio, no computer involved.

The Auto-Tune software used by musicians, apparently can determine the spectral
center of human voice and lock it to a particular musical "key". If the same
software were to be modified to identify when the pitch moved beyond a preset
point (IF passband), then the receiver frequency could be aut
