METHOD FOR AUDIO PROCESSING IN ACCORDANCE WITH IMPULSE ROOM CHARACTERISTICS, SIGNAL PROCESSING UNIT, AUDIOCODER, AUDIODECODER AND BINAURAL RENDERING DEVICE Russian patent published in 2018 - IPC G10K15/12 

FIELD: physics.

SUBSTANCE: audio signal is processed separately from the primary part and the late reverberation in the impulse response of the room, and the processed primary part of the audio signal and the reverbed signal are combined. The transition from the primary part to the late reverberation in the impulse response of the room is achieved when the correlation measure reaches a threshold value, the threshold value being set by the dependent correlation measure for the selected reflection from the primary reflections in the primary part of the impulse room characteristic.

EFFECT: method solves the problem of providing the final audio signal provided to the user, the spatial sensation and the sound depth.
