Latest Patents

One of his latest patents is a scalable and embedded codec for speech and audio signals. This system and method for processing audio and speech signals provide compatibility over a range of communication devices operating at different sampling frequencies and/or bit rates. The analyzer of the system divides the input signal into different portions, with at least one portion carrying sufficient information for intelligible reconstruction of the input signal. The analyzer encodes separate information about other portions of the signal in an embedded manner, allowing for a smooth transition from low bit-rate to high bit-rate applications. Communication devices operating at different sampling rates and/or bit rates can extract corresponding information from the output bit stream of the analyzer. The embedded information generally relates to separate parameters of the input signal or additional resolution in the transmission of original signal parameters. Non-linear techniques for enhancing the overall performance of the system are also disclosed. Furthermore, a novel method of improving the quantization of signal parameters is presented. In a specific embodiment, the input signal is processed in two or more modes depending on the state of the signal in a frame. When the signal is determined to be in a transition state, the encoder provides phase information about N sinusoids, which the decoder uses to improve the quality of the output signal at low bit rates.
