Title: Innovations of Zhong-Qiu Wang

Introduction

Zhong-Qiu Wang is a notable inventor based in Cambridge, MA, who has made significant contributions to the field of audio signal processing. With a total of three patents to his name, his work focuses on advanced methods for improving sound quality and detecting anomalies in audio signals.

Latest Patents

Wang's latest patents include a "Method and system for reverberation modeling of speech signals." This invention discloses a system and method for reverberation reduction, utilizing a Deep Neural Network (DNN) to produce an estimate of a target direct-path signal from a mixture of acoustic signals. The system estimates a filter modeling a room impulse response (RIR) to generate results that closely match the residual between the mixture of acoustic signals and the target direct-path signal.

Another significant patent is the "Method and system for detecting anomalous sound." This invention involves receiving a spectrogram of an audio signal and processing it through a neural network to recover values of the spectrogram for elements in a target region. An anomaly score is determined based on the comparison of recovered values, which is then used for performing control actions.
