Lithe is an object-based audio-graph framework for spatial composition and sound design.
It attempts to define a framework for spatial position processing that is independent of the rendering methods (VBAP, DBAP, Ambisonics, binaural, etc), and tries to work similarly for geometrically regular or irregular speaker layouts. Further, it also inherently allows for cross-adaptive processing between audio and position signals.
This opens up avenues for powerful trajectory generation and manipulation allowing one to define complex spatial effects that are idiomatic to audio synthesis concepts like oscillators, filters, ADSRs, envelopes, etc. It also reduces the parameter complexity in the aesthetic exploration new spatial effects, for example, Spatial Modulation Synthesis, and the ambisonics-based Spatio-temporal granulation.
