This program will convert a .wav sound file to a format known as the .cas
format. It is assumed that the wav file contains a sample of a Classic Atari
cassette tape. This program converts the FSK sounds to the data they are
representing.
The design goal of this project is to retrieve the data that is stored on
cassette tapes. This sounds like a sensible thing to do with a storage
device. That is, unless you design cassette interfaces. The data can be
stored on a mass storage device on some host system. It should be possible
to load the data from the host system into the Classic Atari. The data
could also be re-saved onto cassette tape, thus cleaning up faulty tapes
that contain dropouts, spikes, noise, or other problems. Data that is
damaged can be restored, or repaired. The data on the new tape could be
saved at a higher baudrate, thus reducing the time required to load the
tape. The quality of the cassette tape can be greatly improved in this
way. The various emulators that currently exist, might add support for the
file format used to store the cassette data. Booting a cassette tape on
these emulators could then be implemented, and it could load a tape
instantly. Since the cassette data is retrieved using only a sound card
and some software, there is no need for a cassette unit. Data can be
retrieved from the cassette tapes even if your cassette unit is broken,
unreliable, or otherwise not available. Data that is retrieved from a tape
can be processed, and converted to a disk format.
History:
--------
Release 1.00 may 1997
Release 1.01 somewhere in between, mailed upon requests, skips unsupported
and unrecognized chunks in wav files, which some program create.
Release 1.02 September 2003 added support for 16 bit samples, which some
programs that do not allow setting sample size use.
