A method to improve DRC (Dynamic Range Compressor) performance

摘要：

　　Pure digital amplifier or DSP, with compressing feature (or named Limiter/Compressor/DRC Dynamic Range Compressor), are extensively applied to most of the audio products, even these speaker as tiny as a fist size.Existing problems are well known, especially in the scenario of huge boosting EQ.There are two main problems, one is the disappearance of EQ boosting and attenuating (flattening), another is the low end shifted too low, which causes speaker overdriven and huge distortion.This article presents a method to improve the degradation of DRC sound quality by optimizing signal processing flow.
