Physcial Data

Data to Audio Cassette

Saving data to Audio cassette. Scarcity of resource? The basic principle is to convert either binary or Hex into audio signal, and then reverse the operation (simple......). Found a method for HAM Radio signals to transmit images, system is called Slow-Scan Television.

ctape
