Provided in the present invention are a method, system, device, and electronic signature tool for audio communication modulation scheme self-adaptation. 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, and splices same into a first audio data stream for transmission to a second device; the second device determines, on the basis of the first audio data stream, the modulation schemes correctly received and supported by the first device, modulates by means of the at least two modulation schemes second audio data comprising the modulation schemes correctly received and supported by the first device to generate second audio data code streams, and splices same into a second audio data stream for transmission to the first device; the first device determines, on the basis of the second audio data stream, the modulation schemes correctly received and supported by the second device; and, the first device selects the optimal modulation scheme used thereby and the optimal modulation scheme used by the second device. The method allows for rapid determination of the audio modulation scheme, allows rapid exchange of audio data, and reduces loss of fidelity in exchanged data. |
