Envelop for Live is a free collection of open-source spatial audio production tools that work with Ableton Live Suite.

The free set of tools is designed to make it easy to use space as a compositional element. Three-dimensional sound placement lets you create immersive mixes for multichannel spaces and headphone-based VR/AR environments.

Envelop for Live works with any custom speaker array (minimum 4 speakers) or normal headphones.

Additional details are available at the Ableton site.

Envelop for Live is available now as a free download. It’s open source. The developers note that they have no plans to create a VST or make E4L work with other DAWs, but they support that effort.
