The invention provides an audio encoding method and device, electronic equipment and a storage medium, and relates to the technical field of audio-video coding. The audio enoding method comprises the following steps: acquiring audio data, and sending the audio data to a preset voice encoder; carrying out key frame detection on the audio data through the voice encoder, and determining an audio key frame corresponding to the audio data; performing key quantification processing on the audio key frame to obtain a key quantification result corresponding to the audio key frame; and based on the audio encoder, according to the key quantization result, allocating the coding bit number of the audio key frame during in-band forward error correction coding so as to complete in-band forward error correction coding of the audio data and generate standard audio data corresponding to the audio data. According to the invention, the criticality of the audio frame in the audio data can be analyzed, and then the audio data is encoded according to the criticality of the audio frame, so that the audio quality of the audio data during real-time audio data transmission is improved.
Description
technical field [0001] The present disclosure relates to the technical field of audio and video encoding, and in particular, to an audio encoding method, an audio encoding device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the rapid development of Internet technology, voice codec plays an important role in modern communication systems. Speech coding and decoding can effectively reduce the bandwidth of voice signal transmission, and play a decisive role in saving the cost of voice information storage and transmission and ensuring the integrity of voice information during communication network transmission. Packet loss refers to the phenomenon that the data of one or more data packets (Packet) cannot reach the destination node through the network. [0003] At present, in related schemes, the built-in in-band FEC (Forward Error Correction, forward error correction) module is used to avoid packet loss as much as possible. T...
