Title: The Innovations of Abraham Wei
Introduction
Abraham Wei is a notable inventor based in Saratoga, CA (US). He has made significant contributions to the field of acoustic technology, particularly through his innovative patent in acoustic echo processing systems. His work has implications for various applications, enhancing audio quality and communication systems.
Latest Patents
Abraham Wei holds a patent for an Acoustic Echo Cancellation system. This system and method utilize a digital filter to estimate the echo path, which is divided into two filters: a fixed infinite impulse response (IIR) filter and an adaptive finite impulse response (FIR) filter. The fixed filter is designed to model the composite frequency response of the loudspeaker, its cabinet enclosure, and the direct coupling path between the loudspeaker and the microphone(s). Meanwhile, the adaptive filter addresses the time-varying characteristics of the indirect coupling path between the loudspeaker and microphone. This innovative approach significantly improves the quality of audio processing.
