AUDIO SIGNAL CODING AND DECODING DEVICE USING FREQUENCY-DOMAIN PROCESSOR, TIME-DOMAIN PROCESSOR AND CROSS-PROCESSOR FOR CONTINUOUS INITIALIZATION Russian patent published in 2018 - IPC G10L19/18 G10L21/02 

FIELD: data processing.

SUBSTANCE: invention relates to encoding and decoding of audio signals. In the method, the audio encoder comprises a first processor for encoding a first section of the audio signal in the frequency-domain, comprising a time-frequency converter for converting a first section of the audio signal to a frequency-domain representation, a spectral encoder for encoding a frequency domain representation; a second encoding processor for encoding a second section of the time domain audio signal; a cross processor for calculating the initialization data of the second encoding processor, a controller configured to analyze the audio signal and determine which section of the audio signal is the first section of the audio signal encoded in the frequency domain, and which section of the audio signal is the second section of the audio signal encoded in the time domain; an encoder for generating an encoded audio signal.

EFFECT: providing an advanced principle of audio coding.
