PhaseThree is Audio Damage's detailed plug-in model of the Mu-Tron Bi-Phase, the sought-after twin phaser pedal from the 1970s. Audio Damage bought and dismantled an original unit to capture its behaviour, including the response of its vactrols and the unique sweep of its LFOs, and rebuilt it as a Mac plug-in for your DAW.

Key Features

• Faithful model of the original Bi-Phase hardware, including its quirks and vactrol response
• Two separately controllable phasers that can work together for deep stereo movement
• Original six-stage phasers, plus a twelve-stage option per channel for stronger sweeps
• The rare Bi-Phase expression pedal is modelled as a separate, modulatable parameter
• Cross-platform preset manager, with presets that can move between desktop and iOS versions

How to Download

1. Make sure your DAW supports AU, VST or AAX effect plug-ins on macOS.
2. Use the green Download button on this page to get the package, or visit the developer's website for the current release.
3. Install the plug-in, rescan in your DAW, and place PhaseThree on guitars, keys or synths for classic phasing.

System Requirements

PhaseThree needs a Mac with a recent version of macOS and a 64-bit DAW. Because it is an older plug-in, check the developer's current requirements if you run the very latest macOS release.

FAQs

What hardware is PhaseThree based on?

It models the Mu-Tron Bi-Phase, a vintage twin phaser known for its liquid, subtle stereo phasing. No two surviving hardware units sound exactly alike, so Audio Damage modelled one particularly good example.

Is PhaseThree free?

No. It is a paid Audio Damage plug-in. Use the green Download button on this page or the developer's website to get the current release and pricing.
