AUDIO ENCODER AND DECODER FOR WAVE-FORM CODING WITH INTERLEAVING Russian patent published in 2020 - IPC G10L19/02 

Abstract RU 2713701 C1

FIELD: data processing.

SUBSTANCE: invention relates to encoding and decoding audio signals. Decoding method involves receiving a wave-coded signal having a spectral composition corresponding to a subset of the frequency band above the transition frequency. Wave-coded signal is interleaved with parametric high-frequency reconstruction of the audio signal above the transition frequency.

EFFECT: improved reconstruction of high-frequency bands of an audio signal.
