Violet Crown is a stereo channel strip

 

Six filters. A bus compressor. Zero dollars.

Violet Crown is a stereo channel strip built around the EQ and compression character that defined the sound of major-label bus processing. Three independent EQ bands - each with separate boost and cut controls - feed a custom RMS compressor with program-sensitive auto-release. The VU meters are real, the ballistics are analog, and the whole thing is free. No demo mode. No time limit. No license key. Drop it on a bus and play something.
