Title: The Innovations of Jeffrey D. Klein
Introduction
Jeffrey D. Klein is a notable inventor based in Irvine, CA, with a focus on advancements in echo cancellation technology. He holds a total of 6 patents that showcase his contributions to the field. His work has significantly impacted the way echo cancellers operate, particularly in enhancing audio quality during communication.
Latest Patents
Among his latest patents, Klein has developed methods and systems for automated testing of echo cancellers using natural speech excitations. This innovation involves transmitting a first signal that includes both a speech signal and a marker signal to evaluate the performance of an echo canceller. The process includes receiving a second signal from the echo canceller and aligning the speech signals to determine the choppiness and audible echo based on the state of the non-linear processor.
Another significant patent focuses on perceptual masking of residual echo. This method involves adjusting filter coefficients of an adaptive filter in response to a far-end signal and generating an echo model signal. By subtracting this model from the near-end signal, Klein's method enhances the output signal by emphasizing and de-emphasizing specific spectral regions, improving the overall audio experience.
