AB  - An overview of the high-quality, scalable, low-bitrate KOZ audio codec technology is presented. This new compression method grew out of developments in the control of chaotic systems that allow for the creation of broad spectral components with only a few bits of information. These elements are combined with a high resolution analysis of the audio signal that allows for the signal to be decomposed into peak-like or tonal objects, noise-like objects, transients, and modulations. Psychoacoustic models have been adapted to prioritize and quantize these objects, and the reconstructed signal is built up in layers from the prioritized objects. Metadata and built-in DRM are present in the digital filestream. The decoder is a very low-complexity algorithm that is implemented on a wide variety of portable devices such as cell phones in a software-only solution running on integer processors without DSP support. A demonstration of the quality, scalability and other features of the KOZ format will be given.
