PROCESSOR OF AN AUDIO SIGNAL TRANSMITTER, PROCESSOR OF AN AUDIO SIGNAL RECEIVER, AND ASSOCIATED METHODS AND DATA STORAGE MEDIA Russian patent published in 2022 - IPC G10L19/05 G10L19/02 H04L1/00 

FIELD: audio data processing.

SUBSTANCE: invention relates to audio encoding tools. A frame of code words is assembled, having a code word raster setting the reference positions for a preset total number of code words. Information units are recorded from the first number of information units, starting from the reference positions of a first preset subset of code words, as well as information units from the second number of information units, starting from the reference positions of a second preset subset of code words. The boundaries between the first number of information units and the second number of information units are determined so that the starting information unit from the second number of information units matches the boundary of the code word. Error protection is processed by processing one or more code words from the first or second subset of code words, resulting in a first or second processing result, respectively, and adding the first or second processing result to the preset number of code words, resulting in a set of processed code words.

EFFECT: increase in the efficiency of audio encoding with error protection.
