SPARTA
Aalto University
SPARTA (Spatial Audio Real-Time Applications) is an open-source collection of audio plug-ins for the production and playback of spatial sound scenes, supporting Ambisonics up to 10th order. It provides Ambisonic encoders, loudspeaker and binaural decoders, rotators, beamformers, microphone-array encoders, room simulators, and sound-field visualizers, used in spatial audio research, production, and immersive playback contexts.
History & Background
Developed by Leo McCormack and collaborators at Aalto University, Finland. Internal algorithms are based on the open-source Spatial_Audio_Framework (SAF). The installer also bundles the parametric COMPASS suite, HO-DirAC suite, HOSIRR renderer, and CroPaC binaural decoder, which are released under their own licensing terms.
