FIELD: acoustics.
SUBSTANCE: invention relates to means for generating an audio signal and audio playing. Device comprises a first reproducing means to reproduce the first part of the audio signal based on the first data. Providing means is configured to provide a signal-patch in the second frequency band, wherein the signal-patch is at least partially uncorrelated relative to the first part of the audio signal or is at least partially decorrelated version of the first part of the audio signal, which is shifted to the second frequency band. Second reproducing means is configured to reproduce the second part of the audio signal in the second frequency band based on the second data and signal-patch. Joining means is configured to join the reproduced first part of the audio signal and signal-patch prior to reproducing the second part of the audio signal by the second reproducing means.
EFFECT: technical result is generating and reproducing the audio signal with reducing available data transmission speed.
