Re: [ARSCLIST] Cassette players (pitch correction)

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

With voice-grade stuff, I just don't get too scientific about the EQ. Most of the stuff I've
transferred was recorded so badly it needs some pretty serious EQ for enhanced audibility anyway,
which I do by ear (no beefs from clients so far, many kudos). So net-net, it's far off the standard
curve anyway. But your point is correct and one thing that gives pause about doing this for
music-grade material is I've never seen the 3.75IPS playback EQ curve published anywhere so I
wouldn't know exactly what to compensate when I halved the pitch.
