FIELD: acoustics. ^ SUBSTANCE: invention pertains to the method and device for subsequent processing of a decoded sound signal. The decoded signal is divided into a set of signals at frequency sub-ranges. Subsequent processing is done to at least, one of the signals in the frequency sub-ranges. After processing of at least one signal from the frequency sub-ranges, the signals from the frequency sub-ranges are summed up to form an output decoded sound signal, subject to the next processing. In that way, processing is localised in the necessary sub-range or sub-ranges, leaving the other sub-ranges practically unchanged. ^ EFFECT: increased perceptible quality of the decoded sound signal. ^ 54 cl, 14 dwg |
