TAPESTREA
From Wikipedia, the free encyclopedia
TAPESTREA (Techniques and Paradigms for Expressive Synthesis, Transformation and Rendering of Environmental Audio) is a unified framework and a set of techniques for analyzing, transforming and synthesizing complex environmental sounds. Given one or more recordings, it provides well-defined means to:
- identify points of interest in the sound and extract them into reusable templates
- sinusoidal (deterministic)
- transient (bursty)
- stochastic (noisy)
- transform sound components independently of the background and/or other events
- continually resynthesize the background texture in a perceptually convincing manner using wavelet-tree learning algorithm
- controllably place event templates over backgrounds, using a novel graphical user interface and/or ChucK scripts
- leverage similarity based retrieval to locate other interesting sound components.
TAPESTREA (or taps) makes it possible to completely transform a sound scene, dynamically generate sound scenes of unlimited length, and construct new scenes or compositions by combining elements from different recordings.
Audio/musical applications of TAPESTREA include sound design, soundscape composition, modern forms of musique concrète (pioneered by Pierre Schaeffer and others).
TAPESTREA is free software released under GPL. It was created by Ananya Misra, Perry R. Cook, and Ge Wang at the Princeton Sound Lab, and is actively under development.
