FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology for processing audio signals. An audio frequency signal is resampled using a device for encoding or decoding the audio frequency signal, in which resampling contains following actions for each block of the signal to be resampled: determination by adaptive linear prediction of the number of discrete values of a future signal, wherein this number is determined depending on the selected resampling delay; construction of a resampling reference vector from at least discrete values of a current signal block and determined discrete values of the future signal; and application of a resampling filter to discrete values of the resampling reference vector; provision of switching between two encoding modes; provision of resampling of the current signal block taking into account switching.
EFFECT: technical result is an improvement of the quality of processing of the audio frequency signal.
