A new IC for implementing companding noise reduction in professional wireless microphone applications is described. Unlike existing devices designed primarily for the cordless telephone market, the new design allows straightforward, repeatable implementation of companding schemes incorporating ratios greater or less than 2 to 1, level-dependent ratios, limiters, and noise gates.
