FIELD: physics.
SUBSTANCE: these methods and devices for encoding and decoding audio signals, in particular, the method for endecoding includes receiving the encoded signal on the waveform, having a spectral content corresponding to the subset of the frequency range above the transition frequency. The encoded signal on the waveform is interleaved with the parametric high frequency audio signal reconstruction above the transition frequency, thereby an improved reconstruction of the audio signal high-frequency bands is achieved.
EFFECT: providing an improved reconstruction of the transient processes and the tonal components in the high-frequency bands.
