Patent ID: 6914988

Claim:
An audio reproducing device comprising an input for receiving an n-channel input signal, an output for supplying an 1-channel output signal to 1 loudspeakers, and an audio processing unit for processing the input signal, said audio processing unit comprising enhancing means for enhancing an m-channel signal part of the n-channel input signal, where m<n, the enhancing means having, for each channel signal part of said m-channel signal part, a non-linear anti-symmetric monotone transfer function, characterized in that the audio reproducing device further comprises a speech-music discriminator for providing, in response to one of the channel signal parts of said m-channel signal part designated for speech, a control signal indicating the probability p that said one of the channel signal part comprises speech signals, said control signal being applied to the enhancing means for controlling the enhancing means wherein the transfer function of the enhancing means for each of the m-channel signal parts is dependent on the value of probability p.
