Problems solved by technology

[0006] In the prior art, when audio data is retransmitted in order to solve audio jams, there is no distinction between audio frames, and audio frames including no valid voice are still retransmitted, which wastes audio transmission bandwidth and increases power consumption and time. To solve the problem of delay, this application provides a voice data processing method, system and medium

Abstract

The application discloses a voice data processing method, system and medium, belonging to the technical field of bluetooth audio data processing. The method includes: analyzing the current audio frame to be encoded, and determining the encoding bit rate corresponding to the current audio frame, the encoding bit rate includes a full bit rate, a medium bit rate and a low bit rate, wherein the full bit rate is greater than the medium bit rate, and the medium bit rate The rate is greater than the low bit rate; the number of retransmissions is set according to the encoding bit rate, where the encoding bit rate is positively correlated with the number of retransmissions; the current audio frame is encoded according to the encoding bit rate, and the encoding result is transmitted. According to the characteristics of the audio frame, the present application selects the corresponding encoding rate to encode the audio frame, and sets different retransmission times correspondingly. It reduces the number of retransmissions or even does not retransmit some audio frames for which there is no valid voice, avoiding wasting audio transmission bandwidth, reducing power consumption and delay.

Description

technical field [0001] The present application relates to the technical field of Bluetooth audio data processing, in particular to a voice data processing method, system and medium. Background technique [0002] In the latest Bluetooth Low Energy Audio (Low Energy Audio, LE Audio for short) specification, a point-to-point synchronous stream transmission link technology (Connected isochronous stream, CIS for short) is introduced to realize low-latency audio transmission. When establishing a CIS link, corresponding Quality of Service parameters (QoS for short) will be configured, including the timeout period (Flush Timeout, FT for short), the synchronous link time interval (ISO Interval), and the maximum The number of sub-events (Number of Subevent, referred to as NSE) and the number of packets allowed to be sent within a time interval (Burst Number, referred to as BN), these parameters determine the maximum number of retransmissions for each packet, and during the transmissio...
