Provided is an audio data transmission method comprising the following steps: a first device generates multiple pieces of audio waveform data of different frequencies; the first device splices the multiple pieces of audio waveform data into one audio waveform data stream; the audio waveform data stream is transmitted in a single instance within a same time reference system to a second device via an audio interface of the first device, thus allowing for rapid acquisition of the spectrum characteristics of an audio data communication link, greatly reducing the loss of fidelity in exchanged data, increasing the success rate in data transmission, and improving the quality of data exchange. Also provided in the present invention are an audio data transmission system, an audio data transmission device for use in a mobile terminal, and an electronic signature tool. |
