SPARTA Suite
author: Aalto University
SPARTA is a collection of flexible VST audio plug-ins for spatial audio production, reproduction and visualisation, developed primarily by members of the Acoustics Lab at Aalto University, Finland.
The SPARTA installer also includes the COMPASS suite, the HO-DirAC suite, CroPaC Binaural Decoder, and the HO-SIRR room impulse response renderer. These plug-ins employ parametric processing and are signal-dependent. They aim to go beyond conventional linear Ambisonics algorithms, used by the baseline SPARTA plug-ins, by extracting meaningful parameters over time and subsequently employing them to map the input to the output in an adaptive and informed manner.
