FIELD: physics.
SUBSTANCE: device for processing audio signal, containing a sequence of blocks of spectral values, includes a processor for calculating a signal under the influence of aliasing using at least one first modification to the first block of a sequence of blocks, and using at least one different second modification value for the second block of a sequence of blocks and for estimating the error signal due to aliasing, representing the error due to aliasing in the signal influenced by aliasing. The combination module combines the signal influenced by aliasing and the error signal due to aliasing.
EFFECT: increasing the efficiency of audio signal processing.
