BBCut2: incorporating beat tracking and on-the-fly event analysis

BBCut2 is the latest manifestation of a software library for realtime algorithmic audio splicing. Machine listening capabilities are supported for realtime beat tracking and audio event analysis, such that splicing manipulations respect component events, and their micro-timing with respect to an inferred metrical structure. The architecture, whilst currently most effective for transient rich percussive signals, is modular enough to be extensible to new observation models. A scheduling system is described that can cope with splicing driven from an external clock, empowering realtime beat tracking led segmentation and other processing effects.
