Abstract: Disclosed herein are an audio processing apparatus and method. In an embodiment, if a playing mode that abruptly changes the level of audio being played has been input, the data of the audio is processed to mitigate the abrupt change in the level of the audio and converted into analog signals, and the analog signals are output. In an embodiment, if a playing mode that causes a jump from the current track of the audio being played to another track is input, the audio data is divided by an exponential function of 2 before the jump to the another track is completed. In another embodiment, if a playing mode that rapidly moves a playing position to another location on the same track has been input, the audio data is divided by a specific exponential function, and is then multiplied by the exponential function after the playing mode has been completed.
