Abstract

The invention relates to an audio transmission method, a terminal, electronic equipment and a storage medium, and the audio transmission method comprises the steps that a first terminal sends a plurality of audio packets to a second terminal, and each audio packet in the plurality of audio packets comprises an audio frame at the current moment and a preset number of redundant audio frames before the current moment; the first terminal receives feedback of the second terminal for the received audio packet; the first terminal determines an audio packet received by the second terminal according to the feedback, and determines an audio packet needing to be retransmitted according to redundant audio frames in the audio packet received by the second terminal; and the first terminal sends the audio packet needing to be retransmitted to the second terminal.

Description

technical field [0001] The present disclosure relates to the field of signal processing, and in particular to an audio transmission method, a terminal, electronic equipment and a storage medium. Background technique [0002] In the process of real-time communication, due to the actual situation of the network, the loss of audio data is unavoidable. When network packet loss occurs, the sound quality heard by the receiving end will be very poor, and even the sound sent by the sending end cannot be heard clearly. So the recovery of audio data lost during real-time communication is a necessary technology. [0003] The recovery of lost audio data mainly includes forward error correction (FEC, Forward Error Correction) technology and retransmission technology. The main method of the FEC technology is that the sending end adds a part of redundant information when sending the audio packet, so that the receiving end can recover the lost data through the redundant information when t...
