The invention discloses an audio connection method and device, and belongs to the field of audio processing. The method includes obtaining a first audio for an audio connection, and determining a first transition bar in the first audio; determining chord information corresponding to the first transition bar according to the chord arrangement information of the first audio; acquiring a second transition bar matching the first transition bar and a corresponding second audio thereof from an audio library according to the chord information of the first transition bar; and using a preset transitionalgorithm to connect the first audio and the second audio on the basis of the first transition bar and the second transition bar. The two audios are connected on the transition bars with the same chord information, so that the connected audio can meet the harmony music theory and the sense of hearing, and the purpose of fast and smooth connection of the two audios can be achieved, the efficiencyand the intelligence of audio connection are improved, the optional range of the audio is large, and the flexibility is good.
