Latest Patents

Ramesh Katuri's latest patents include methods and apparatus systems for unified speech and audio decoding improvements. One of his notable inventions is an apparatus designed for decoding an encoded Unified Audio and Speech stream. This apparatus features a core decoder that utilizes a fast Fourier transform (FFT) module based on the Cooley-Tuckey algorithm. The FFT module is adept at determining a discrete Fourier transform (DFT) by recursively breaking it down into smaller FFTs. This process involves applying twiddle factors that refer to pre-computed values. Additionally, his patents cover the decoding of an LPC filter quantized using a line spectral frequency (LSF) representation, which includes various computational techniques for reconstructing and calculating the LPC filter.

Another significant patent by Katuri involves methods, apparatus, and systems for unified speech and audio decoding and encoding decorrelation filter improvements. This invention also features a core decoder that includes an upmixing unit for mono to stereo upmixing. The upmixing unit incorporates a decorrelator unit that applies a decorrelation filter to the input signal, determining filter coefficients by referring to pre-computed values.
