Title: The Innovations of Malcolm Law
Introduction
Malcolm Law is an inventive mind based in Steyning, GB. He has made significant contributions to the field of audio technology, particularly in the realm of lossless audio watermarking and bandwidth extension. Despite having no patents to his name, his work has influenced the industry and showcased his expertise.
Latest Patents
Malcolm Law's latest innovations include two notable patents. The first is titled "Transparent Lossless Audio Watermarking." This invention provides an encoding method and encoder for transparent lossless audio watermarking by quantizing an original PCM audio signal twice. Each quantization is done to a quantization grid, which reduces the amount of introduced quantization error and shapes the error spectrally. The technique decorrelates signal alterations from the original audio, making the error more similar to additive noise. Additionally, a decoding method and decoder are provided, along with a method of altering the watermark without fully decoding the encoded signal.
The second patent is "Doubly Compatible Lossless Audio Bandwidth Extension." This encoder for digital audio signals operates at a higher sample rate, creating a stream for consumer distribution at a lower sampling rate. It maintains compatibility with standard PCM players without requiring a decoder. With a suitable decoder, two enhanced playback options are available, allowing for full lossless reconstruction or lossy bandwidth extension, even if the transmission chain has truncated the least-significant-bits of the encoder's output signal.
