METHOD, DEVICE AND SYSTEM FOR PROCESSING AUDIO DATA Russian patent published in 2018 - IPC G10L19/00 G10L21/02 

FIELD: physics.

SUBSTANCE: noise frame of an audio signal is received. The current noise frame is expanded to the noise signal of the low frequency band and the noise signal of the high frequency band. The noise signal of the low frequency band is encoded and transmitted by using the first intermittent transmission mechanism. The noise signal of the high frequency band is encoded and transmitted by using the second intermittent transmission mechanism.

EFFECT: decrease in the bandwidth and an improvement in the quality of the audio data encoding.
