摘要:
A method for processing an audio signal (400) in accordance with a room impulse response (434) is described. The audio signal (400) is separately processed (422, 424) with an early part and a late reverberation of the room impulse response (434), and the processed early part (428) of the audio signal and the reverberated signal (430) are combined (432). A transition from the early part to the late reverberation in the room impulse response is reached when a correlation measure reaches a threshold, the threshold being set dependent on the correlation measure for a selected one of the early reflections in the early part of the room impulse response.
