He has made significant contributions to the field of audio technology, particularly in noise cancellation and echo cancellation systems. With a total of 2 patents, his work has had a considerable impact on enhancing audio communication.
Latest Patents
One of Thierry Le Gall's latest patents is for a system designed for uplink noise cancellation. This innovative system comprises audio logic that converts captured sound into an audio signal. It also includes transmission logic that adds noise to the audio signal. The processing logic is adapted to partially remove the noise from the audio signal by subtracting a noise waveform, resulting in a clearer audio output. The system generates the noise waveform using power level information associated with the transmission logic, ultimately transmitting the result signal to another electronic device.
Another significant patent is for a method and apparatus for acoustic echo cancellation utilizing dual filters. This technology is particularly useful for hands-free phones, employing one fast adapting filter and one slow adapting filter. The system includes a switching mechanism with hysteresis based on recent performance. The fast adapting filter features step size control to limit relative filter update energy, while the slow adapting filter prevents filter divergence.
