Patent ID: 7895138

Claim:
An audio data processing device, comprising an audio redistributor for generating a first number of audio data output signals (z 1 . . . z M ) to be output on a first number of output channels based on, and in response to, a second number of audio data input signals (x 1 . . . x N ) received on a second number of input channels; and an audio classifier, responsive to the second number of audio data input signals, for generating gradually sliding control signals (P), in a gradually sliding dependence on types of audio content according to which the second number of audio data input signals (x 1 . . . x N ) are classified, wherein the audio redistributor further generates the first number of audio data output signals (z 1 . . . z M ) from the second number of audio data input signals (x 1 . . . x N ) in response to the gradually sliding control signals.
