Abstract
A method, system and apparatus for audio communication modulation mode self-adaptation, and an electronic signature token are provided. The method includes generating a first audio detection frame; if the first audio detection frame is correct, selecting the modulation mode supported by the second device corresponding to the identifier of the modulation mode supported by the second device from pre-stored modulation modes supported by the second device according to the identifier of modulation mode supported by the second device carried in the first audio detection frame, and generating a first audio detection feedback frame; if the first audio detection feedback frame is correct, demodulating an audio data frame from the second device using a demodulation mode corresponding to the modulation mode supported by the second device, and demodulating an audio data frame from the first device using a demodulation mode corresponding to the modulation mode supported by the first device.
