You can use Jay McKnights program on the MRL website to calculate a
table of offsets to compensate for this. I don't have the exact link
handy, but I think the program is magtapeeq or magtapeq.
It is the program Jay uses to provide compensation tables in Choosing
and Using an MRL test tape.
Whenever you do this you want to use resampling conversions because any
of the other change speed or pitch (that work alone) don't sound as good
as plain simple resampling.
You can build the EQ into an FFT filter and save it for future reference
in the DAW.

The way I understand it is that if you digitize at double the desired sample rate (at least for 1 7/8), and then just play the file back at the desired sample rate, there is no funny digital pitch shifting going on. It's like a true varispeed. But the problem is that shifts the playback EQ down an octave, right?
