AUDIO SIGNAL PROCESSING METHOD, SIGNAL PROCESSING UNIT, STEREOPHONIC RENDER, AUDIO CODER AND AUDIO DECODER Russian patent published in 2018 - IPC H04S7/00 G10L19/00 H03M7/30 

FIELD: physics.

SUBSTANCE: in this audio signal processing method, according to the room impulse response, the audio signal is processed using an early portion of the room impulse response separately from the late room reverberation of the room impulse response, wherein the late reverberation processing comprises forming a scaled reverberant signal, wherein the scaling depends on the audio signal. The processed early portion of the audio signal and the scaled reverberant signal are combined.

EFFECT: identity of the late reverberation of the room impulse response to the result of convolution of an audio signal with a full impulse response.
