[Coco] Cassete reading

[Gustavo Ranaur Schoenaker]

Actually I'm, in this first part, trying to read the cassetes. I have some
disks, took. Eventualy I'll try to read them, but first I need to fix my
CoCo keyboard. And then, your program will be very, very useful.

Meanwhile I'm trying to recover the tapes. I'm getting beated by them.
Reading on XRoar is not pratical.

I'm writting a reader in Octave (quite easy to write). If it rains this
weekend I'll probably have an alpha version :-)

Does exsit any program that reads "damaged" tapes? I know it is not easy
task.

However my idea is playing the same tape many times and hoping that the
error (specially mecanical errors, when the tape slides in different
speeds, distorcing the signal) doesn't happens in the very same place.

And, I normally recorded everythig twice, so it will be too much misfortune
to have the same error in the same block in two different records.

I think with this I can be able to recover a lot os information. Ok, Murphy
can play its part. I'm just givin trouble to him. :-)

Is there any program that "inspect" the tape, like your program for disks?
Which one? It will save me some time programming (ok, ok, I'm having fun
doing it :-)
