ABSTRACT:
An encoder and a decoder is provided with each being usable independently of each other for improving the dynamic range of clipped speech digital systems by providing amplitude components to the clipped digital signal. The encoder processes an audio input signal along two signal paths, the first signal path including a clipper and digitizer means for forming a digitized clipped signal. The second signal path includes a rectifier, envelope detector and digitizing means for forming a digitized signal having amplitude components. Both digitized signals may then be transmitted to the decoder for reconstruction or stored for reconstruction at a later time.
