APPARATUS AND METHOD FOR HANDLING TRANSIENT SOUND EVENTS IN AUDIO SIGNALS WHEN CHANGING REPLAY SPEED OR PITCH Russian patent published in 2016 - IPC G10L19/02 G10L19/22 G10L21/38 G10L21/04 

FIELD: acoustics.

SUBSTANCE: invention relates to means of audio signal processing. Device comprises time manipulator for individual treatment in time of plurality of sub-bands of sound signal. Time manipulator consists of covering and summation stages for covering and summation units, at least one of plurality of subband signals using value of covering and summation, which differs from improved value in module extraction, detector of transient processes to detection of transient process in audio signal or subranges signal, and multiple transient processes adders for summation of detected transient processes with multiple signals generated at stage of covering and summation. Stage of covering and summation is tuned to reduced effect of detected transient processes or for elimination of detected transient processes in combination.

EFFECT: technical result consists in reduction of influence of transient processes at sound quality.
