The open-source BlueLab audio plug-ins are being developed again!
https://github.com/nicolasdittlo/newlab-plugins
There are some very powerful and unique processors here, especially unique in the space of FOSS plug-ins.
The official builds are sold commercially, the developers ask politely that people don't publish their own builds (so they can fund continued development).
If you've never used them - try them!
Old builds were on Archive.org (when the official repos were gone for years).
