Systems and methods for high resolution signal analysis and chaotic data compression

摘要

Systems and methods for processing, compressing, and distributing data, such as an audio file, are provided. Single- and multi-channel data streams are transformed into a single signal in a Unified Domain. A high resolution frequency analysis based on phase evolution provides accurate frequency estimates and distinguishes between oscillatory and noise-like signal components. The unified signal components are then prioritized using a Psychoacoustic Model. The prioritized components can be arranged in layers based on the component priorities and compressed (e.g., with a chaotic compression scheme). The least psychoacoustically important layers can be removed to lower the transmission bitrate. Digital rights management tools based, for example, on a unique device identification can be used for secure distribution.
