Latest Patents

Yuepeng Li holds a patent for a "System, method and apparatus with environmental noise cancellation." This invention is designed to improve audio reception by utilizing a receiver module with at least two inputs. The first input captures the main audio portion, while the second input focuses on the audio that contains a majority of environmental noise. The system calibrates these audio signals to minimize errors caused by differences between the inputs. By employing adaptive beamforming technology and a speech extractor, the system effectively separates environmental noise from the main audio. The process includes transforming audio signals from the time domain to the frequency domain, applying non-linear noise suppression technology, and finally outputting a sequence of audio signals after transforming back to the time domain.
