Hi John - Yes, the good news is that's what I'm looking for.
The bad news is my tapes are not CUTS format. However, the good
news is it comes with sources. The bad news is it's in FORTH!
The good news is I like hacking FORTH (Just finishing up a board
game that plays in a Sun Open Boot Prom machine w/o Solaris ;)
but this is over my head (bad news).

Anyway I might have to look at writing something in gcc that
can detect tones and demod, make a project out of that. Just
checking to see if someone has already invented that particular

Audio is from the Altair 88-ACR.
