Title: Gaël Richard: Innovator in Audio Signal Processing

Introduction

Gaël Richard is a notable inventor based in Viroflay, France. He has made significant contributions to the field of audio signal processing, particularly in methods for enhancing sound quality.

Latest Patents

Richard holds a patent for a "Method for suppressing the late reverberation of an audio signal." This innovative method involves calculating a plurality of prediction vectors and generating observation vectors from the modulus of the complex time-frequency transform of an input signal. Additionally, synthesis dictionaries are constructed from these observation vectors. The late reverberation spectrum is estimated from the synthesis dictionaries and prediction vectors, allowing for the filtering of observation vectors to eliminate late reverberation and obtain a dereverberated signal modulus.
