Gravity Feed for SPARTA
How plans relate to the SPARTA encoder, panner and binauraliser.
This guide explains how Spatial9 Gravity Feed relates to SPARTA, the free spatial audio plugins from Aalto University. Status: documented route, no profile yet. SPARTA plugins such as the Ambisonic encoder, the VBAP panner and the binauraliser expose per-source azimuth and elevation as host-automatable parameters, but Gravity Feed has no SPARTA profile.

Planned route
- Read each SPARTA plugin's parameter list in your host to find the source azimuth and elevation parameters and their ranges.
- Convert Gravity Feed degrees to the host's normalized values with those ranges, as the REAPER prototype does for IEM.
- Run a fixture test and publish a profile with its status.
What you can do today
Request plans in the playground or over the API, then apply the positions in SPARTA by hand.
FAQ
Does SPARTA support distance?
The encoder and panner work with directions. Gravity Feed returns distance changes as unsupported actions for direction-only targets.
Why SPARTA as well as IEM?
Both are free and widely used in research. SPARTA's binauraliser is useful for headphone checks.
