Problems solved by technology

[0004] However, when using the above method to achieve anti-packet loss, whether it is out-of-band FEC or out-of-band FEC+ARQ, it is necessary to increase the number of data packets sent, and the additional data packets sent will occupy part of the bandwidth and affect the bit rate of audio transmission.

Abstract

The embodiment of the invention discloses an audio data sending method and device, an audio data receiving method and device, a terminal and a storage medium, and belongs to the field of audio coding and decoding. The method comprises the steps that m-level audio coding is conducted on an nth audio frame, m-level coded data of the nth audio frame are obtained, the coded data of different levels correspond to different code rates, and m is an integer larger than or equal to 2; an nth audio data packet is generated based on the m-level coded data of the nth audio frame and historical coded data of historical audio frames before the nth audio frame, and the code rate of the coded data corresponding to the nth audio frame in the mth audio data packet is higher than the code rate of the historical coded data corresponding to the historical audio frames; and sending the nth audio data packet to an audio receiving end. By adopting the scheme provided by the embodiment of the invention, the packet loss resistance of audio data transmission can be improved under the condition of not increasing sent data packets.

Description

technical field [0001] The embodiments of the present application relate to the technical field of audio coding and decoding, and in particular, to an audio data sending method, receiving method, device, terminal, and storage medium. Background technique [0002] With the development of network technology, real-time voice communication using the network as the carrier can be realized between terminals. Due to the unreliability of Internet transmission, audio data transmitted based on the Internet is prone to packet loss. [0003] At present, there are mainly two methods for anti-packet loss, namely forward error correction (Forward Error Correction, FEC) and automatic repeat request (Automatic Repeat-reQuest, ARQ). In related technologies, out-of-band FEC or out-of-band FEC+ARQ mode is mainly used to combat packet loss during network transmission. [0004] However, when using the above method to achieve anti-packet loss, both out-of-band FEC and out-of-band FEC+ARQ need to ...
