DEVICE AND METHOD FOR PROCESSING AUDIO SIGNAL CONTAINING TRANSIENT SIGNAL Russian patent published in 2016 - IPC G10L21/04 

FIELD: acoustics.

SUBSTANCE: invention relates to means of processing an audio signal with transition. Audio signal is processed, wherein the first part is removed containing a transient signal, or an audio signal with transition to obtain a resultant processed signal. Second temporary portion is inserted in the processed audio signal, from where the first portion was removed, or where the transient signal in the processed audio signal is located; herewith the second portion contains the transient signal, which has not been processed unlike the initial signal, where the signal processing stage is made with the possibility of extending the audio signal without the transient part, by means of which the first part is extended to the second part, more prolonged in time than the first part, and the module of signal insert has the possibility of copying part of the audio signal containing the transient signal, as well as parts before and after the transient signal so that with summation of the first part and parts being previous and subsequent to the transient signal to have a signal equal by duration to the second part. Insert module is configured to insert a non-modified copy into the processed audio signal or to insert the signal copy containing the transient part, where only the initial part or the end part have been modified.

EFFECT: technical result is the improvement of audio signal quality.
