Not audio (though there is an app that will decode

converts them into a .T64 file directly. For alignment/phase, there's
a graphical mode that scrolls the data up the screen along with "guard
bands" that show where the app thinks a 0 and a 1 are. You use the
cursor keys to align the data from the tape drive and the guard bands
for optimal data parsing. Once you have an offset from this process,
you can use it as a command-line parameter for bulk reading.
COOL! Where can I get this app?
It works well enough, but I really wish the source
were available (it
never seems to be for DOS programs, unlike Unix and Amiga software).
Is the author listed in the program? Have you tried contacting them?
I have a small pile of PET Rabbit-format tapes that I
want to extract
from. My BASIC 2.0 PET needs repair (keyboard problems), so I can't
just read the data and save it to disk. I have plenty of 8032s, but
only one 2001 (got the 80-col PETs from university surplus for $10 a
few years ago; we got the 40-col, 32K PET when I was grade-school for
$1175).
I have tons of software on tape for the PET and other platforms and will
want to digitize all the images at some point.
