For some reason, I always get very happy when a new freeware compressor is released. Especially if it was coded by Christian Budde!
Released under the Audiocation logo, this plugin is actually another piece of great work by Christian. A quote from the Audiocation website:
The AC1 Compressor is a dynamic processor plug-in optimized for low CPU usage whilst maintaining the highest precision in signal processing. It features a free adjustable knee and an input transformer simulation to add some harmonic distortion and character to your signal.
The developer has stated that the plugin may be updated soon with more sound coloring options and a switchable sidechain. For now, it doesn’t really add too much mojo to the processed signal, but what makes it stand out of the crowd for me are it’s clean GUI and simple controls. And it does just what a simple compressor should do. Test it out for yourself and enjoy!
