Latest Patents

One of his latest patents is titled "Method, system and apparatus for allocating bits in perceptual audio coders." This invention presents a non-iterative and computationally efficient bit allocation technique for perceptual audio coders that employ uniform quantization schemes. The method involves computing a target MNR for all critical bands in a frame using a target bit rate and associated SMRs. Associated SNRs are then computed for the critical bands, and bits are allocated based on these computed SNRs.

Another significant patent is "System, method, and apparatus for fast quantization in perceptual audio coders." This technique encodes an audio signal based on a perceptual model. In one embodiment, it shapes quantization noise in the spectral lines on a band-by-band basis using their local gains. The noise-shaped spectral lines are then fitted within a predetermined bit rate to form an encoded bit stream.
