Abstract: An audio playback method and device are provided. The method comprises: receiving an instruction for rate adjustment, wherein the instruction for rate adjustment is used for adjusting an audio playback rate from a first multiple of a preset standard rate to a second multiple of the preset standard rate (S101); creating a second audio filter with the second multiple (S102); calling the second audio filter to perform rate change processing according to the second multiple on second audio data in a first cache to obtain third audio data, wherein the second audio data is obtained after a first audio filter performs first processing on first audio data, and the first processing comprises at least one of the following: audio decoding, format conversion, sampling, and channel conversion (S103); and playing the third audio data (S104). By means of the method, the playback smoothness of a player with respect to audio data is improved.
