Latest Patents

Jacques Prado holds a patent for a method designed to denoise an acoustic signal for a multi-microphone audio device operating in a noisy environment. This method involves several key steps: first, partitioning the spectrum of the noisy signal into high-frequency (HF) and low-frequency (LF) parts. Next, it applies differentiated denoising processes for each part of the spectrum. For the HF part, denoising is achieved by predicting the useful signal from one sensor to another within a first sub-array using an adaptive algorithm estimator. For the LF part, the method predicts the noise between sensors of a second sub-array, also utilizing an adaptive algorithm estimator. The final steps include reconstructing the spectrum by combining the denoised signals and selectively reducing noise through an Optimized Modified Log-Spectral Amplitude gain process.
