He has made significant contributions to the field of audio signal processing, particularly in the area of acoustic echo cancellation. With a total of 2 patents, his work has advanced the technology used in various audio applications.

Latest Patents

Shmuel's latest patents include innovative techniques for reducing echo in audio signals. One of his patents focuses on "Infinite impulse response acoustic echo cancellation in the frequency domain." This methodology involves estimating an echo path transfer function associated with a received audio signal, which includes a combination of a speech signal and a reference signal modified by the echo path transfer function. The approach utilizes both an infinite impulse response (IIR) filter and a finite impulse response (FIR) filter to effectively model different echo components. The filters are applied to generate an echo correction signal, which is then subtracted from the received audio signal to enhance the clarity of the speech signal.

Another significant patent is "Joint beamforming and echo cancellation for reduction of noise and non-linear echo." This invention provides techniques for estimating transfer functions of echo paths from audio signals received through a microphone array. The methodology includes the cancellation of linear components of the echo and the estimation of a speech path RTF associated with the speech signal. The process also involves performing beamforming on the processed signals to improve audio quality.
