The method comprises the following steps: a first device modulates first audio data by means of at least two modulation schemes to generate first audio data code streams, splices same into a first audio data stream, and transmits same to a second device via an audio interface; the second device selects the optimal modulation scheme used thereby on the basis of the first audio data stream; the second device modulates second audio data comprising the optimal modulation scheme used by the second device by means of the at least two modulation schemes to generate second audio data code streams, splices same into one second audio data stream, and transmits same to the first device via the audio interface; and, the first device selects, on the basis of the second audio data stream, the optimal modulation scheme used by the first device. The method allows for rapid determination of the audio modulation schemes, allows for rapid exchange of audio data, and greatly reduces loss of fidelity in exchanged data.
