Patent ID: 7158764

Claim:
A system for sending high fidelity sound between wireless units, comprising: an audio interface operable to receive audible sounds and generate first and second analog signals that represent the audible sounds; a coding module operable to encode a portion of the first analog signals and a portion of the second analog signals at least in part by: receiving the first and second analog signals from the audio interface; sampling the first analog signals at a first rate; grouping at least two samples of the first analog signals to represent the portion of the first analog signals; sampling the second analog signals at a second rate; and grouping at least two samples of the second analog signals to represent the portion of the second analog signals, the first and second rates combining to form a rate greater than eight kilohertz such that the audible sounds represented by the portion of the first analog signals and the portion of the second analog signals are encoded at a combined rate greater than eight kilohertz; and a wireless module operable to transmit the first encoded portion over a first synchronous channel and the second encoded portion over a second synchronous channel.
