eqMac vs Fader: EQ-first vs volume-first on Mac

eqMac and Fader look like competitors but solve different problems. eqMac is EQ-first: a free, system-wide equalizer that shapes how your Mac sounds, with a per-app Volume Mixer locked behind its paid Pro plan. Fader is volume-first: a keyboard-driven per-app mixer and audio router, one-time $19.99, with no EQ at all. Pick eqMac if you want to change the tone of your audio; pick Fader if you want to change how loud each app is and where it plays — fast, from the keyboard.

Both apps live at the macOS audio layer, both can set a different volume for each running app, and both get recommended on the same "per-app volume for Mac" threads. That's why people compare them. But the two were built around different jobs, and once you see which job is yours the choice gets easy. This is an honest look at where each one is genuinely better — including the cases where eqMac wins.

What eqMac is really for

eqMac is an equalizer first and everything else second. Its free tier gives you a system-wide EQ — a basic bass/mids/treble control, a 10-band advanced equalizer, and AutoEQ headphone correction that pulls tuning profiles for thousands of headphone models. That's a real, useful, free product, and the older codebase is open source. If your Mac's built-in speakers sound thin or your headphones need a correction curve, eqMac fixes the sound in a way nothing in this category else does for free.

The per-app Volume Mixer — letting you set Spotify, Zoom, and a browser to different levels — exists in eqMac, but it sits in the paid Pro tier alongside the Expert EQ, a spectrum analyzer, AudioUnit effect hosting, and spatial audio. eqMac Pro is a subscription of roughly $3 per month, or a one-time lifetime license (around $40). So if all you want from eqMac is per-app volume, you're paying for a Pro plan whose headline features are about EQ and effects, not levels.

What Fader is really for

Fader does two things and skips the rest: per-app volume and per-app output routing, both driven from the keyboard. You hit a toggle hotkey, the keyboard becomes a mixer — one column of letter keys per app — and you ride levels without reaching for the mouse or hunting through a menu. You can also send one app to a different output device: music to AirPods, a call to your headset, alerts to the desk speakers, no virtual cables to wire up.

Fader has no equalizer. It won't correct your headphones or boost the bass. That's deliberate — it's a mixer and a router, not a sound processor. It's a one-time $19.99 with a 3-day free trial (no account, no card up front), and it needs macOS 14.4 or later because it uses the modern audio framework Apple shipped in 14.4.

eqMac vs Fader, side by side

The cleanest way to see the split is feature by feature. Note where each app's free-versus-paid line falls — that's where most of the real decision lives.

Where eqMac is the better pick

Be honest about this: if you want to shape your sound, eqMac wins, and it wins for free. Laptop speakers that sound boxy, headphones that need a correction curve, a podcast that's too bright — that's EQ work, and Fader simply doesn't do it. The free 10-band equalizer plus AutoEQ is a genuinely strong package, and if you also dip into per-app volume now and then, paying for eqMac Pro can cover both needs in one app. For an EQ-led workflow, eqMac is the right answer.

Where Fader is the better pick

If volume is the thing you actually touch all day — dropping music when a call starts, muting a browser, balancing a stream — the equalizer is beside the point, and you're left comparing the two on how fast and how cheaply you can ride levels. That's Fader's lane. The whole interface is the keyboard, so a volume change is a keystroke instead of a trip to the menu bar, and per-app output routing is built in rather than absent. On price, Fader's per-app volume is a flat one-time $19.99, while eqMac's is behind a Pro plan you either subscribe to or buy a separate lifetime license for. If you're choosing for volume and routing alone, Fader is the leaner, faster, pay-once option.

A note on keyboard control

eqMac does support keyboard shortcuts, so "keyboard" alone isn't the whole story. The difference is what the keyboard is in each app. In eqMac, shortcuts trigger an app whose home is a visual EQ and mixer panel. In Fader, the keyboard is the mixer — the letter keys are the faders, and you adjust levels in place without a panel ever coming up. If you're the kind of person who resents reaching for the mouse to nudge a volume, that distinction is the entire pitch.

Bottom line

This isn't really eqMac versus Fader — it's EQ versus volume. eqMac is the better, cheaper choice if you want to shape how your Mac sounds, with per-app volume as a Pro add-on. Fader is the better choice if per-app volume and routing is the daily job and you want to drive it from the keyboard for a one-time $19.99. Buy eqMac for tone. Buy Fader for fast, pay-once control of how loud each app is and where it goes.
