Latest Patents
One of his latest patents is titled "System and method for combined non-linear and late echo suppression." This invention involves a method, computer program product, and computer system designed to receive an input signal. The system generates a first power spectral density estimate for a linear reverberant component and a second estimate for a non-linear reverberant component. By combining these estimates, the system can reduce undesired signal components in the output signal through residual echo suppression.
Another significant patent is "Spectral estimation of room acoustic parameters." This invention includes a system and method for estimating reverberation parameters using an adaptive, parametric, linear prediction filter. The filter utilizes power spectral density estimates from multiple channels to estimate parameters related to reverberation time and Direct-to-Reverberant Ratio (DRR). The adaptation process minimizes a cost function, allowing for real-time adjustments without requiring a training phase.
