<p>An audio reproducing device is provided with an input for receiving an n-channel input signal, an output for supplying an l-channel output signal to l loudspeakers, and an audio processing unit for processing the input signal. The audio processing unit comprises enhancing means for enhancing an m-channel signal part of the n-channel input signal, whereby 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. The audio reproducing device is further provided with a speech-music discriminator, which, in response to one of the channel signal parts of said m-channel signal part designated for speech, generates a control signal indicating the probability p that said one of the channel signal parts comprises speech signals. By means of this control signal the enhancing means are controlled.</p> |
