## What is SimplyLowPass?

A simple but fast low-pass filter with control over cutoff frequency and resonance factor. The filter exists in an AUv3 app extension so it is available for use in any host app that supports AudioUnit components such as AUM or Cubasis or GarageBand. This app is just a delivery mechanism for the AUv3 app extension and a demo of how it works.
