Actually, since you wanted the new speed to be 0.25 of the
original, the inverse of 0.25 = (1 / 0.25) = 4.0 ... so using -by
4.0 then using the python script to set the sample rate to 48000
would have also worked.
But your method is effectively the same thing (in reverse) so
the end result file is the same.
Glad I could help, but it sucks that the tape was that much
faster. Re-recording at 96k would probably really help to
maintain fidelity.
