Audiotap is a program for conversion between .TAP files and Commodore
64 tapes. It can read WAV files containing the sampled sound of a
tape and convert them to .TAP files, and can generate WAV files to be
recorded on a tape and used on a Commodore 64. It can also record
.TAP files from the sound card and turn .TAP files into sound played
to the sound card. It does not require custom-built cables, just
plain audio cables connecting the sound card and a normal audio tape
player/recorder.
