Problems solved by technology
The traditional audio compression method adopts a unified coding compression method to perform complex coding and compression on all audio data, and decode it at the opposite end after the transmission is completed. Therefore, based on the current coding technology, it is impossible to further reduce the amount of data and the demand for bandwidth.

The invention discloses an audio transmission method and device, and the method comprises the steps: dividing first audio data into a plurality of audio data segments which are continuous in time, carrying out the VAD detection, marking the audio data segments as effective audio data segments or mute audio data segments according to a detection result, coding the effective audio data segments, andadding a data packet header; carrying out data transmission on a plurality of time-continuous effective audio data segments; and restoring the mute audio data segment and decoding the effective audiodata segment according to the plurality of transmitted time-continuous effective audio data segments, and combining the effective audio data segment, the mute audio data segment and the position information to form second audio data. In the data transmission process, only the effective audio data segments are transmitted, the mute audio data segments do not need to be transmitted, the mute audiodata segments are restored by marking the position information of the mute audio data segments and then combined, audio data transmission is achieved, and due to the fact that the mute audio data segments are not transmitted, the data transmission amount is greatly reduced, and the requirement on the bandwidth is reduced.
Description
technical field [0001] The present invention relates to the technical field of audio transmission, in particular to an audio transmission method and device. Background technique [0002] Smart electronic devices such as earphones, recording pens, translators, and smart speakers generally use Bluetooth to connect to mobile phones to transmit audio to the mobile phone. However, with the continuous improvement of the intelligence of electronic equipment, the application scenarios are becoming more and more complex. For example, traditional Bluetooth headsets only need to transmit music or phone audio, while smart Bluetooth headsets may need to transmit language translation audio or recorded audio while transmitting music or phone audio. As the amount of data to be transmitted gradually increases, the demand for data bandwidth is also increasing, which leads to the inability of the transmission bandwidth and transmission speed of Bluetooth to meet the requirements.
