FabFilter Volcano 3

Nothing beats a vintage sounding, gritty and creamy cut-off filter. That's exactly what FabFilter Volcano has been known for since its first release in 2005. Today, Volcano 3 delivers the best in creative filtering with a completely redesigned innovative interface that is an absolute delight to work with.
The Volcano 3 app filters the microphone input and plays it back in real-time. To use Volcano 3 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Volcano 3 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
