FabFilter Pro-L 2

FabFilter Pro-L 2 is a professional, feature-packed true peak limiter, suitable for transparent mastering as well as single instrument limiting. It features various different limiting algorithms, a highly intuitive interface, oversampling, dithering and accurate loudness and true peak metering: everything you need in a limiter!
The Pro-L 2 app filters the microphone input and plays it back in real-time. To use Pro-L 2 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Pro-L 2 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
