When companding is applied to low signal levels, the noise floor of the radio signal becomes dynamic and audible. Most wireless users will recognize these low-level artifacts as “breathing” or “pumping.” The “breathing” sound results from the suddenly increased level of the noise floor and tends to be masked at higher signal levels.

Companding is a common technique for reducing the data rate of audio signals by making the quantization levels unequal. 2. How Compander works. A Compander is a non-linear circuit which provides high amplification for low input amplitude signals and low amplification for high input amplitude signals. A compander operates in a transmitter to compress audio signals before …
