Title: Innovations of Zhongjin Wang in Audio Processing

Introduction

Zhongjin Wang is a notable inventor based in Beijing, China. He has made significant contributions to the field of audio processing, particularly in enhancing playback quality. His innovative approach addresses common issues related to background noise during audio playback.

Latest Patents

Zhongjin Wang holds a patent for a technology titled "Compressor target curve to avoid boosting noise." This invention focuses on the processing of audio signals during playback. It ensures that audio signals falling below a specified threshold loudness level are processed to prevent unwanted background noise from becoming audible. The technology involves receiving N-channel audio from a playback volume controller and comparing the audio level with a threshold level. If the audio level exceeds the threshold, it is processed with a first amount of gain according to a dynamic range control compression curve designed for professionally produced audio. Conversely, if the audio level is less than or equal to the threshold, it is processed with a second amount of gain to avoid amplifying background noise. After applying the gain, the audio is sent to a downstream device.
