FIELD: physics, computer engineering.
SUBSTANCE: invention relates to radio engineering and is intended for controlling an audio signal, including a transient event. The device comprises a unit for replacing a transient signal, configured to replace the transient part of a signal, which includes a transient event of an audio signal, with part of a replacement signal adapted to energy characteristics of the signal of one or more transient parts of the audio signal, or to the energy characteristic of the signal of the transient part of the signal to obtain an audio signal with a shorter transient process. The device also includes a signal processor configured to process an audio signal with a shorter transient process to obtain a processed version of the audio signal with a shorter transient process. The device also includes a transient signal inserting unit configured to merge the processed version of the audio signal with a shorter transient process with the transient signal, representing in the original or processed form the transient content of the transient part of the signal.
EFFECT: high accuracy of reproducing the signal.
