Re: [ARSCLIST] Cassette players (pitch correction)
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.

The EQ will be incorrect when transferring at double speed. If you want
to sound as correct as possible, you will need to make EQ adjustments in
addition to the pitch correction.
By the way, you can find a pitch correction calculator here:
I have a spreadsheet which computes the EQ correction for various pitch
changes. When I finally have a moment, I hope to put that up as a general
purpose web calculator.
