An audio data transmission method includes using a first device such as a mobile terminal for obtaining audio data to be transmitted. The first device modulates the audio data to be transmitted using at least two modulation modes respectively, wherein the modulation mode is an amplitude modulation, a frequency modulation, a carrier modulation or a subcarrier modulation. This generates audio data frame streams in the at least two modulation modes. The audio data frame streams are obtained by modulating the audio data to be transmitted into an analog waveform signal using the modulation modes of the first device so as to generate the audio data frame streams. The first device also splices the audio data frame streams in the at least two modulation modes into an audio data stream. The splicing is able to be without a time interval or with a time interval, and is undertaken to combine the analog waveforms that have been modulated using the at least two modulation modes. The audio data stream is transmitted to a second device in one transmission in the same time reference frame via an audio interface of the first device. |
