UZU Frequency-Domain Phaser is Free

To celebrate 10k subs on Twitter and Youtube, audio developer Ewan Bristow is giving away UZU, his Frequency-Domain Phaser for FREE... for the next 7 days only (article posted 1st May 2026). You can of course donate to his audio development, some of which we have covered here. Hear the plugin in action with Au5 and find out more details below.. 

Conventional phasers work in the time domain, using phase shifts and tiny delays to create a handful of notches (usually 12 or 24 at most)...

UZU flips the table
It operates in the frequency domain using an FFT (Fast Fourier Transform), allowing up to 8192 notches, a scale traditional phasers simply can't reach. This way, notches are sharp, bubbly and are just how we think phasers should sound!

Features

• 1: Distance between each spectral notch
• 2: Main phase-offset of the filter shape
• 3: Add sharpness and depth to each notch
• 4: Automatic offset-control speed
• 5: Overall mix of the plugin
• 6: Rounds spectral bins for rhythmic "pulses"
• 7: Weighs the filter to either Hz or Log
• 8: Speed and offset 5x multiplier
• 9: Preserves low-end frequencies under 250hz
• 10: Change the spectral-engine's blocksize

It's available as VST3, CLAP,  AU with versions for Windows, Mac and Linux
