Purix Raw

Purix Raw is a free one-knob resonance and harshness tamer for macOS. Turn the single PURIFY knob and harsh resonances, boxiness, and sibilance get pulled down by a spectral suppressor that tracks the peaks in real time and tames them, auto-leveled so the track gets cleaner without getting quieter. From a light polish to firm taming, it works on vocals, drums, synths, and the whole mix.

One knob, instant cleanup. No band-picking or threshold-setting — drop it on a channel and turn it up; the dynamic engine finds the harsh frequencies and rides them down for you.

Note: like all FFT-based resonance tools it reports a small, automatically compensated latency — best used while mixing rather than for live monitoring.

Formats: AU, VST3, and Standalone — Universal Binary (Apple Silicon + Intel), code-signed and notarized by Apple so it installs cleanly on macOS. Free to download.
