Latest Patents

Anibal Ferreira holds a patent for a "Method and apparatus for audio encoding and decoding using wideband psychoacoustic modeling and bandwidth extension." This novel bandwidth extension technique allows information to be encoded and decoded using a fractal self-similarity model or an accurate spectral replacement model, or both. Additionally, he has developed a multi-band temporal amplitude coding technique that serves as an enhancement to any coding or decoding technique. This technique aids in the accurate reconstruction of the temporal envelope and employs a utility filter bank. Furthermore, his perceptual coder utilizes a comodulation masking release model, which typically operates with more conventional perceptual coders, making the perceptual model more accurate and increasing the efficiency of the overall perceptual coder.
