Abstract

See full text

The present application relates to a method and a circuit for dynamic range control based on peak level and RMS level double-level detection. The method includes: processing an input signal by an equalizer, to obtain an equalized signal; detecting a signal peak level and a signal RMS level of the equalized signal, to obtain the signal peak level and the signal RMS level; adjusting a parameter configuration of a dynamic range controller according to the signal peak level and the signal RMS level; adjusting a dynamic gain of the dynamic range controller according to the parameter configuration, and adjusting the equalized signal by using the adjusted gain, and then outputting the adjusted equalized signal. The method can not only control the dynamic range of the signal but also improve the clipping distortion of the signal.
