AUDIO ENCODER AND AUDIO DECODER Russian patent published in 2023 - IPC G10L19/08 

Abstract RU 2810027 C2

FIELD: computer engineering.

SUBSTANCE: processing audio data. The technical result is achieved by representing each parameter as a vector through an index value that can take N values; calculating one or more symbols, the calculation including: calculating the difference between the index value of the second element and the index value of its previous element in the vector: and applying a modulo N operation to the difference; associating at least each of one second element with a corresponding symbol out of one or more symbols, and encoding at least each of one second element by entropy encoding the symbol associated with at least one second element based on the probability table , containing the probabilities of the symbols.

EFFECT: increase of efficiency and quality of the encoded audio signal.
