The best guitar noise gate plugin for iPad and Apple Silicon Macs.

Purrist is a state-of-the-art noise suppressor designed primarily for use with electric guitars. Its ability to preserve your guitar's sustain distinguishes it from other plugins and hardware gates. The three sections of the plugin target AC hum, white noise, and other interference.

Buzz: A very clever hum-canceller filters out AC interference. No more buzzing single coils!
Fizz: This dynamic shelving filter cuts out high frequencies when decaying string runs out of higher harmonics. It handles white noise and whiny power adapters.
Noise: A classic expander-type noise gate smoothly removes other noise not covered by the previous sections.

This app has a standalone mode, but is intended to be used as an Audio Unit (AUv3) plugin in your favourite iPad (or Apple Silicon Mac) DAW.
