Dynastia

Dynastia has a couple of features that none of the other free OTT plugins offer: per-band stereo width controls and Mid/Side processing modes. You can independently widen or narrow the low, mid, and high bands, which is pretty useful for keeping the low-end mono while widening the highs. The plugin also includes per-band distortion (called Excite), separate upward and downward thresholds for each band, a real-time visualizer, and oversampling up to 4x.

0 rebuilt the crossover filters to reduce phase-cancellation issues present in the original release. Unfortunately, the big limitation is platform support. Dynastia is Windows-only as of March 2026. The developer (a solo hobbyist from Finland) has mentioned that Mac versions “will probably be available in the future,” but there’s no timeline. If you’re on Windows and want stereo imaging tools built into your OTT plugin, Dynastia is the only free option that does this.

Mac users will have to look elsewhere.
