Abstract:
A method for processing an audio signal in accordance with a room impulse response is described. The audio signal is processed with an early part of the room impulse response separate from a late reverberation of the room impulse response, wherein the processing of the late reverberation has generating a scaled reverberated signal, the scaling being dependent on the audio signal. The processed early part of the audio signal and the scaled reverberated signal are combined.

Claim (Index 13):
A signal processing unit, comprising:\n an input for receiving an audio signal, an early part processor for processing the received audio signal in accordance with an early part of a room impulse response, a late reverberation processor for processing the received audio signal in accordance with a late reverberation of the room impulse response, the late reverberation processor configured to generate a scaled reverberated signal; and an output for combining the processed early part of the received audio signal and the scaled reverberated signal into an output audio signal, wherein the late reverberation processor configured to generate a scaled reverberated signal by\n setting a gain factor according to a predefined correlation measure of the audio signal comprising a fixed value determined empirically on the basis of an analysis of a plurality of audio signals, and applying the gain factor, or \n calculating a correlation measure of the audio signal using a correlation analysis of the audio signal and the gain factor, and applying the gain factor.
