Soundtoys PhaseMistress – Analog Phase Shifter Plugin (ELECTRONIC LICENCE DOWNLOAD)

OVERVIEW

PhaseMistress brings the unmistakable richness of classic analog phasers into the digital world, capturing the iconic tones of units like the Bi-Phase, Phase 90, Small Stone, Moogerfooger, and more. Soundtoys analysed dozens of legendary phasers to recreate their warmth, movement, and musical character, then expanded the possibilities with 69 unique style presets and fully adjustable circuit-level controls. From smooth two-stage sweeps to extreme 24-stage modulation, PhaseMistress puts a complete collection of vintage phasers – and much more – at your fingertips.

But this plugin goes far beyond hardware. PhaseMistress includes a powerful modulation engine with LFO modes, step and random patterns, rhythmic sequencing, envelope following, and even the ability to draw your own waveshapes. It reacts musically to your audio, making it perfect for rhythmic drums, funky guitars, synth lines, or dramatic vocal textures. Whether you want subtle animation, classic rock sweep, or experimental phase-driven sound design, PhaseMistress delivers unmatched creative control.

Note: Delivered as an ELECTRONIC LICENCE DOWNLOAD – no physical product.

“PhaseMistress is the best-sounding phaser I’ve heard since I put my favorite hardware phaser back in the box.” — Richard Hilton (Producer, Engineer, Keyboardist with Nile Rodgers Productions)

 

“…rock-solid emulation of classic pedals.” — Remix Magazine

 

“I like the animation of sound that is possible with PhaseMistress. The LFO, Envelope Follower, and Rhythm mode became essential as percussion modeling effects. You can completely crush drum sounds and get some really odd phase shifting sounding effects.” — Richard Divine (Artist, Producer, Programmer, Remixer)

Known Issues and Notes

• In Digital Performer 11, discrete parameters behave incorrectly for VST3. Soundtoys recommend using VST2 or AU in Digital Performer 11 until the issue can be resolved.
• Some hosts will automatically replace VST2 plug-ins in sessions with matching VST3 versions, depending on the DAW and your DAW preferences. The Soundtoys VST3 versions are fully interchangeable with their VST2 counterparts, but not all hosts implement this feature of VST3.

Note about DAW / Computer Support

Sountoys cannot guarantee support if you are using a supported host platform listed above on an operating system or computer that is not supported by the host platform itself. Please visit your DAW’s website or manual to ensure you are using a compatible system.

If your DAW is not on the list above or if your supported DAW version is older than what’s listed, it doesn’t necessarily mean that our plug-ins won’t work. It just means that it has not been tested. If something goes wrong with an unsupported DAW, you are welcome to write to support, but Soundtoys cannot guarantee a solution. They currently recommend using their free trial with your host to confirm compatibility on your computer.

32-Bit Plug-in Support

With the release of 5.3.2, Soundtoys have officially discontinued support for 32-bit plug-ins. With macOS Catalina requiring all applications to be 64-bit, and with the vast majority of our PC customers using 64-bit plug-ins, they decided it was the right time to end 32-bit support. Their most recent 32-bit installers are available to download below.
