Latest Patents

Gavin's latest patents include a method and system for handling resonance-induced echo components. This invention presents an echo suppression unit designed for electronic devices that utilize both a loudspeaker and a microphone. The unit captures a transmit signal that includes an echo of a receive signal rendered by the loudspeaker. It intelligently determines whether the receive signal contains a frequency component that causes distortion and applies a post-filter to selectively attenuate this distortion.

Another notable patent is related to subband domain echo masking for improved duplexity of spectral domain echo suppressors. This invention describes a circuit that attenuates a subband of a transmit signal captured by the microphone. The circuit assesses voice activity in both far-end and near-end signals, determining the necessary subband attenuation to enhance the quality of hands-free communication.
