Title: Innovations of Guillaume Vitte
Introduction
Guillaume Vitte is a notable inventor based in Paris, France. He has made significant contributions to the field of audio technology, particularly in noisy environments. With a total of six patents to his name, Vitte's work focuses on enhancing audio signal processing.
Latest Patents
One of his latest patents is a method for denoising an acoustic signal for a multi-microphone audio device operating in a noisy environment. This method involves several steps, including partitioning the spectrum of the noisy signal into high-frequency (HF) and low-frequency (LF) parts. Denoising processes are applied differently to each part, utilizing adaptive algorithm estimators for both HF and LF components. The final steps include reconstructing the spectrum and selectively reducing noise using an Optimized Modified Log-Spectral Amplitude gain process. Another significant patent is a method for selecting one microphone from two or more microphones for a speech processor system, such as a hands-free telephone device. This method digitizes sound signals, executes a short-term Fourier transform, and applies a decision rule based on a speech-presence confidence index to select the most suitable microphone for speech processing.
