AUDIO ENCODER WITH SIGNAL-DEPENDENT PRECISION AND NUMBER CONTROL, AUDIO DECODER AND RELATED METHODS AND COMPUTER PROGRAMS Russian patent published in 2022 - IPC G10L19/02 

FIELD: computer technology.

SUBSTANCE: invention relates to the field of computer technology for encoding audio data. The effect is achieved by pre-processing the input audio data to obtain the audio data to be encoded; encoding the audio data to be encoded; and controlling encoding such that, depending on the first signal characteristic of the first frame of audio data to be encoded, the number of audio data elements for the audio data to be encoded for the first frame is reduced compared to the second signal characteristic of the second frame, and the first number of information units used to encode the reduced number of audio data items for the first frame is more significantly improved compared to the second number of information units for the second frame.

EFFECT: increasing the bit rate and quality of audio data playback.
