Latest Patents

Wierzynski's latest patents include a method for noise weighting filtering. This invention is utilized to shape noise in both time domain and frequency domain coding schemes. The method employs a noise weighting filter based on a filterbank with variable gains. It presents a technique for decoding an encoded signal using received side information and a masking matrix derived from the masking properties of speech. The encoded signal is separated into subband signal components, which are then multiplied by corresponding gain values based on the masking matrix. These components are combined to produce a decoded signal. Another patent also focuses on a method for noise weighting filtering, emphasizing the computation of gains in the noise weighting filterbank with filter parameters derived from speech masking properties. Illustrative embodiments of this method in various coding schemes are provided.
