Blindfold EQ Free Download

If you're trying to EQ by ear but keep looking at the numbers, Blindfold EQ handles that by removing every visual reference. It’s a free download that forces you to listen, not look.

You get a straightforward 4-band EQ with Low Shelf, Low Mid, High Mid, and High Shelf filters. The catch is that every single knob is completely blind—there are no frequency labels, no gain readouts, and no Q value indicators. You turn knobs based solely on what you hear. This approach is inspired by a quote from engineer Matt Wallace in the book Recording Unhinged by Sylvia Massy, focusing on pure auditory decision-making.

The Controls

Four EQ Bands The plugin provides four filter types: a Low Shelf, a Low Mid bell, a High Mid bell, and a High Shelf. You adjust each band’s frequency, gain, and bandwidth (Q). Completely Blind Interface All parameter knobs have no numerical values, tick marks, or visual feedback of their settings. You don't see the frequency you’re adjusting, the amount of gain you’re applying, or the Q width.

Technical Specs & Formats

This is a fresh air plugin in terms of compatibility. It comes as a VST, Audio Units, VST 3, AAX, and CLAP plugin for macOS, Windows, and Linux. There’s also an iOS version that works as a mobile audio app, so you can practice this ear-training approach on a tablet.

Who Should Use Blindfold EQ

This fits a few specific scenarios. It’s useful for mixing engineers and producers who feel they’ve become overly reliant on visual meters and want to break that habit. It also works for students or anyone actively training their ears, providing a dedicated tool for making EQ choices without numerical crutches. If you’re processing audio on an iPad and want a simple, focused EQ, the iOS app version covers that.

Final Verdict

Grab this if you need a no-cost tool to practice or enforce ear-based EQ decisions across desktop or mobile. You get a well-made, multi-format EQ that literally hides all the data. The trade-off is the complete lack of visual feedback, which is the entire point—but it means you can’t recall precise settings or communicate them easily. If your goal is to train your ears or mix purely by listening, this audiothing free download is built for that job.
