Latest Patents
Raymond Chen holds a patent for a "Scalable and embedded codec for speech and audio signals." This invention discloses a system and method for processing audio and speech signals, ensuring compatibility over a range of communication devices that operate at different sampling frequencies and bit rates. The system's analyzer divides the input signal into different portions, with at least one portion carrying sufficient information for intelligible reconstruction of the input signal. Additionally, the analyzer encodes separate information about other portions of the signal in an embedded manner, facilitating a smooth transition from low bit-rate to high bit-rate applications. This innovative approach allows communication devices to extract corresponding information from the output bit stream, regardless of their operating parameters. The invention also includes non-linear techniques for enhancing overall system performance and a novel method for improving the quantization of signal parameters.
