SNDX Ref
Know exactly what your mix sounds like — and how it compares to anything you admire.
Drop SNDX Ref on any track or bus. It shows you a real-time spectrum of your mix and overlays the spectrum of any reference track you load. Every comparison plays back at loudness-matched levels, so your ears make decisions based on tone — not volume.

Make better decisions, faster
See your frequency balance
A real-time spectrum analyzer shows you exactly what's happening in your mix — lows, mids, highs — at a glance. No more guessing why something feels off.
Compare against any reference
Load a reference track and see its spectrum overlaid on yours. Instantly spot where your mix has too much low-end, a harsh mid, or a lacking top.
Loudness-matched playback
Switch between your mix and your reference at the same perceived loudness. Your ears stop being fooled by volume differences and start hearing actual tonal differences.
Works in any DAW
Drop SNDX Ref on your master bus, a group, or any individual track. Available as VST3 and AU for Mac and Windows — works in Ableton, Logic, FL Studio, and more.
Train your ears over time
Regularly referencing builds ear memory. After a few sessions you'll start hearing problems before you even open the plugin — making you a faster, more confident mixer.
One-time price, lifetime updates
Pay once and own it. All future updates are included — no subscription needed. Or get it as part of the SNDX plan alongside all other plugins and 200 credits/mo.
