Provided are a self-adaptive method, system and device for audio communication modulation modes, and an electronic signature tool. The method comprises: a first device using a first modulation mode supported by the first device to modulate identifier information about the first modulation mode supported by the first device and identifier information about a first modulation mode supported by a second device to generate a first audio detection frame, and sending same to the second device; when the first audio detection frame is correct, according to the first modulation mode supported by the second device, the second device modulating the identifier information about the first modulation mode supported by the first device and the identifier information about the first modulation mode supported by the second device to generate a first audio detection feedback frame, and sending same to the first device; and when the first audio detection feedback frame is correct, the first device conducting two-way communications in the demodulation mode for the first modulation mode supported by the first device and the demodulation mode for the first modulation mode supported by the second device. The present disclosure can determine the audio modulation mode and demodulation mode quickly, thereby enabling audio data to interact quickly, and reducing the degree of distortion of the interactive data greatly. |
