This disclosure relates to the field of communication and
interaction technology, specifically to an audio transmission method, an audio transmission device, and an audio
transmission system. The audio transmission method applied to the transmitting end includes: acquiring a stereo audio
stream; mixing a first-channel audio
stream and a second-channel audio
stream to obtain a mixed audio stream for the first channel
processing at the receiving end; determining
square wave signal data corresponding to the mixed audio stream based on the transmission information of each audio frame in the mixed audio stream, for the second channel
processing at the receiving end; combining the mixed audio stream and the
square wave signal data, and transmitting the combined data via a first connection and a second connection pre-established with the receiving end, respectively, so that the receiving end can switch between the first audio stream received via the first connection and the second audio stream received via the second connection, thereby improving switching accuracy, reducing switching latency, and ensuring the smoothness and continuity of audio playback.
