Read full description

A simple but straightforward phaser audio effect to give you that nice retro feel. Unlike the SimplyFlange effect that is also available, this filter does not involve any delay buffer. Rather, it uses a string of all-pass filters to generate out-of-phase copies of the input signal. These are mixed together to produce the classic phasing effect. The filter lives 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. You can also experiment with the audio effect directly in this app.
