Ableton and Envelop—a non-profit directed by Christopher Willits—have offered up a free set of tools for working with 3D spatial audio, VR, and AR.

Envelop for Live is a free set of tools—you need the full version of Ableton Live 10 Suite to run it—for working with spatial audio production and live performance. The packaged includes a mixer for panning audio sources, specialized effects including multi-format delays and reverbs, sound shapers, and more—it also gives developers a way to create their own effects.
