AUDIO DECODER, DEVICE FOR FORMING OUTPUT ENCODED AUDIO DATA AND METHODS ALLOWING THE INITIALIZATION OF DECODER Russian patent published in 2018 - IPC G10L19/00 H03M7/30 

FIELD: physics.

SUBSTANCE: invention relates to the field of audio coding / decoding. Audio decoder includes a determination device made to determine whether the frame of the encoded audio data is a special frame that contains the encoded audio sample values and additional information containing the encoded audio-sampling values of several frames preceding the special frame to initialize the decoder to be able to decode the audio-sampling values associated with the special frame if the special frame is the first frame after the decoder starts. Decoder comprises an initialization device made to initialize the decoder, wherein the initialization of the decoder comprises decoding of the encoded audio-inset values inputted into the additional information before to decode the encoded audio-sample values associated with the special frame.

EFFECT: technical result is to ensure the delivery of audio content via a transmission channel with a variable bit rate and improve the sound quality.
