This new virtualizer uses the Accelerate framework to process samples. I've bundled a HeSuVi impulse for now, and will add an option to select an impulse in the future. It will validate the selection before sending it to the actual filter, which outright fails if it receives invalid input. Impulses will be supported in any arbitrary format that Cog supports, but let's not go too hog wild, it requires HeSuVi 14 channel presets.
