Save digital data onto a Compact Cassette using a format resembling that of Commodore Datassette.
Needs a config file named config.yml. Example:
device: -t alsa "hw:0"
bitlen: 16
volume: 0.98
Usage:
- encoding:
./tape-write.rb < FILE - decoding:
./tape-read.rb > FILE
Explanation and videos in this blog post.
tape-write.rb encodes data from stdin to the sound card. tape-read.rb records from
the sound card and decodes to stdout.
A WORD OF WARNING. Before running the script, please make sure that your speakers are turned off. For noise immunity, the signal contains a lot of power. That means it is very loud, and its spectral composition is guaranteed to turn your speakers into a long-range acoustic weapon.
Requires SoX.
