APPARATUS AND METHOD OF PROCESSING AUDIO SIGNAL CONTAINING TRANSIENT SIGNAL Russian patent published in 2015 - IPC G10L21/04 

FIELD: physics, acoustics.

SUBSTANCE: invention relates to means of processing an audio signal with transition. The method comprises processing an audio signal in which a first portion containing a transient signal is removed or a signal with transition to obtain a resultant processed signal. A second temporary portion is inserted in the processed audio signal from where the first portion was removed or where the transient signal is located in the processed audio signal. The second portion contains a transient which has not been processed unlike the initial signal, where the signal insertion process comprises determining the duration of the second portion which is copied from the audio signal with transition. The initial point or final point of the second portion is determined by finding the maximum number of cross-correlating parameters; thus, the boundary of the second portion maximally coincides with the corresponding boundary of the processed signal, where the temporary point of the transient signal in the processed audio signal coincides with the point of the transient signal in the initial audio signal or deviates therefrom, wherein the deviation is allowable from the perspective of psychoacoustics after applying preliminary and subsequent masking procedures.

EFFECT: higher signal quality.
