Abstract
A dynamic range compressor of a subband type for carrying out a dynamic compression on a broadband input signal includes a subband splitting device for splitting the broadband input signal into K narrowband subband signals. An amplifier unit amplifies each of the K subband signals to obtain K amplified subband signals. Further, a subband combining device is provided for combining the K amplified subband signals to obtain a broadband output signal, which is a dynamically compressed version of the broadband input signal. An envelope detecting device generates, for each of the K subbands, a respective one of K envelope signals. An amplifier control device generates, in dependence of the K envelope signals, K amplifier control signals, each being representative of one of the K amplification factors. The amplifier control device is adapted to generate an amplification control signal in dependence of more than one of the K envelope signals.
