Abstract
A process and corresponding system for encoding and decoding digital data in analog signals is disclosed. Digital data values are represented by concurrent combinations of distinct audio tones, which combine to create chords. The chords have multiple identifiable parameters that can be modulated to represent the data values. For instance, the modulated chords can include a concurrent combination of distinct tones that each have a different frequency and a different starting time. The frequencies of the tones and the starting times of those tones can be modulated to create unique combinations that represent respective data values. As such, analog audio content of a given chord can be used to represent a particular data value and the analog audio signals can be transmitted between nodes in a communication network in order to communicate that data value.
