Abstract: The present invention discloses an audio signal processing system, a loudspeaker and an electronics device. The audio signal processing system having a clipping threshold estimator, which receives an input audio signal and outputs at least one clipping threshold; and an audio processing unit, which receives the input audio signal, processes the input audio signal to control the non-linear distortion added to the input audio signal based on the clipping threshold and outputs an output audio signal to a loudspeaker driver, wherein the clipping threshold estimator includes: an extraction unit which extracts a set of features from the input audio signal; and a regression or classification unit which receives the set of features and converts the set of features into the at least one clipping threshold by using a regression or classification processing.
