Abstract

A system and method of audio peak limiting is provided, which drives gain calculation by setting a moving maximum window, and combines matching the moving maximum window length to the delay duration of the audio input signal to suppress the risk of overshoot while enabling the user to flexibly adjust the appropriate start time, and the gain curve is smoother, reducing distortion in dynamic range processing, thereby obtaining a more natural auditory perception.
