Latest Patents
One of Zopf's latest patents is titled "Scalable and embedded codec for speech and audio signals." This invention discloses a system and method for processing audio and speech signals, providing compatibility across various communication devices that operate at different sampling frequencies and bit rates. The system's analyzer divides the input signal into different portions, ensuring that at least one portion carries 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 innovation allows communication devices operating at different sampling rates and bit rates to extract corresponding information from the output bit stream of the analyzer. The invention also includes non-linear techniques for enhancing overall system performance and a novel method for improving the quantization of signal parameters.
