Disclosed is an automatic audio distortion control method and apparatus, wherein the automatic audio distortion control apparatus comprises an amplifier ( 6 ) and a feedback loop which has its both ends coupled to an input and an output of the amplifier ( 6 ), wherein said feedback loop has clipping distortion of signals outputted from the amplifier ( 6 ) as a control parameter for automatic control on the distortion of the amplifier ( 6 ). Once the outputted level gets close to a limit-value of speakers, the method and the apparatus will regulate power amplifier gain automatically, in order to control distortion, prevent damage to the speakers, and provide compatibility with high or low levels inputted from various audio sources.
