Latest Patents

Umezawa's latest patents include "Signal processing control in an audio device" and "Audio signal shaping for playback by audio devices." The first patent describes methods, systems, and apparatus for controlling audio signal processing. It involves obtaining a measure of coupling between at least one microphone and one speaker associated with an audio device. This measure is utilized to control audio signal processing, including sidetone generation and the application of multi-channel decorrelation to the audio signal. The second patent presents a technique for limiting distortion of an audio signal during playback. This technique compresses the audio signal to generate a compressed audio signal that does not exceed a specified compression limit. The compressed audio signal is then soft clipped to produce a soft-clipped audio signal, ensuring that it remains within a defined soft clipping limit.
