    Abstract: A method and system for communicating audio signals at a low bit rate and yet retaining significant representation of the original signal is disclosed in this patent This method interweaves both compressed audio and a messaging protocol into a data stream that can be transmitted over any digital communication medium thus eliminating the need for higher levels of protocol overhead. A digitally sampled wave (from a microphone) is accumulated in a memory and subsequently compressed by finding a maximum value (peak) followed by a minimum value (valley) and recording the count of the number of samples between the peak and valley. A digital band pass filter (BPF), such as an IIR or FIR, is used on the input raw wave to smooth and eliminate noise thus increasing compressibility. A protocol consisting of commands and information are interwoven with the compressed signal. This interwoven protocol data is de-commutated prior to regeneration of the signal.
