ENCODING MODE DETERMINING METHOD AND DEVICE, THE AUDIO SIGNALS ENCODING METHOD AND DEVICE AND THE AUDIO SIGNALS DECODING METHOD AND DEVICE Russian patent published in 2019 - IPC G10L19/05 G10L19/04 G10L19/12 G10L19/22 

FIELD: data processing.

SUBSTANCE: invention refers to the means for determining the encoding mode and for encoding/decoding of audio signals. By means of the signal characteristics based at least one processing device determining the current frame class from among the plurality of classes including the music class and the voice class. Obtaining the features parameters from plurality of frames including the said current frame. Based on the features parameters determining whether the error occurs in the current frame particular class. When an error occurs in the current frame particular class and the current frame particular class is the music class, correcting the current frame particular class to the voice class. When an error occurs in the current frame particular class and the current frame particular class is the voice class, correcting the current frame particular class to the music class.

EFFECT: technical result consists in the caused by the encoding mode frequent changes delays reduction.
