Sound Control vs Fader: which per-app mixer fits you?

Pick Sound Control if you want deep per-app audio processing — a real equalizer, AutoEQ headphone calibration, balance controls and MIDI — and you're fine paying a subscription. Pick Fader if what you actually need is fast per-app volume and output routing, driven from the keyboard, for a one-time $19.99. Both control each app's level; they differ on how much they do beyond volume, on how you reach the controls, and on how you pay.

macOS still ships no built-in volume mixer — one master output, and that's the end of it. Sound Control and Fader both fill that gap, so this isn't a "which one works" question. It's a "which tradeoff fits how you work" question. Below is an honest look at each, including the places where Sound Control clearly does more than Fader.

What Sound Control is

Sound Control, by Static Z Software, is a long-running and genuinely powerful Mac audio app. It's built around per-app control, and it goes deep: per-app volume, a per-app graphic equalizer (10- or 31-band), Audio Units support, and thousands of searchable AutoEQ headphone calibration profiles you can load and tweak. It can reroute an app's audio to any output device — send music to a USB interface while everything else stays on the internal speakers — and adjust left-right balance (or downmix to mono) per app and per device. It also does MIDI mapping, "priority devices" that switch automatically when you plug them in, and hotkeys that control volume, mute and EQ for the foreground app, plus a shortcut to mute all background apps.

That's a broad, mature feature set — Sound Control is arguably the most audiophile-leaning app in this category, and the EQ and headphone calibration are its real signature. Two things are worth knowing going in. First, the current version (Sound Control 3) is on the Mac App Store as a free download with a subscription for the full feature set: $1.99 per month or $14.99 per year. Static Z sold a one-time direct license for older versions, but the shipping App Store version is subscription-based. Second, all that depth means more surface area to learn if you only came for "turn one app down."

What Fader is

Fader is a per-app volume mixer and audio router for Mac, sold on the Mac App Store for $19.99 one-time with a 3-day free trial. It does the same core job — every running app gets its own level — but its whole design is about reaching that level fast. Hit a toggle hotkey and your keyboard becomes the mixer: one column of letter keys per app, so you ride volumes without moving your hands to the menu bar or the mouse. It can also send each app to its own output device, so music can stay on speakers while a call goes to your headset. It runs on macOS 14.4 or later and, being a sandboxed App Store app, installs without a separate audio driver to manage.

Fader deliberately does less than Sound Control. There's no equalizer, no headphone calibration, no MIDI. The trade is focus: per-app volume and routing you reach in a keystroke, paid for once and kept. If you want EQ, Sound Control (or an EQ-first tool) is the better fit — see eqMac vs Fader for the EQ-first-versus-volume-first split.

Side by side

Read the table honestly and the shape is clear. Sound Control does more — EQ, headphone calibration, balance, MIDI — and charges for it on a recurring basis. Fader does less, faster, for a single payment. Which side wins depends entirely on whether you want an audio workstation or a fast volume mixer.

The keyboard difference

Both apps can set Spotify to 30% and a call to 100%. The gap you actually feel is how you get there, and how many apps you can reach at once. Sound Control's hotkeys are built around the foreground app: handy shortcuts to raise, lower, mute or EQ whatever window is in front, plus one shortcut to mute everything in the background. That's useful, but it's focus-based — the keys always target the active app.

Fader's model is different. Toggle it on and every app you've added gets its own column of letter keys — Q/A/Z is one app, W/S/X the next — so you can nudge the app in the background without ever switching to it. If your day is riding several app levels at once (call, music, browser, alerts), that per-app addressing is the part you feel. If your day is mostly "turn the front app down," Sound Control's foreground hotkeys cover it fine.

The price question: subscription vs one-time

This is the honest crux for a lot of people. Sound Control's subscription is inexpensive month to month — $14.99 a year is not much — but it's ongoing, and it buys you a genuinely deeper toolkit. Fader is $19.99 once. Over a single year the two are close in cost; past that, the one-time app costs nothing more while the subscription keeps renewing. Neither is "the ripoff" — you're paying recurring money for more features, or paying once for a narrower, faster tool.

So the price decision follows the feature decision, not the other way around. If you'll use the EQ and calibration, the subscription is buying something real. If you won't, you're renting depth you don't touch, and a one-time volume mixer is the cheaper long-run answer.

Which should you pick?

Choose Sound Control if you care about sound quality shaping as much as volume: per-app EQ, AutoEQ headphone profiles, balance, Audio Units or MIDI. It's the more capable audio app of the two, and if you'll use that capability, the subscription earns its keep.

Choose Fader if your real need is fast per-app volume and output routing without the extra machinery — and if you'd rather pay once than subscribe. The 3-day trial lets you confirm the keyboard workflow fits before you buy.

Bottom line

There's no loser here. Sound Control is a deep, EQ-first per-app audio app that also handles volume and routing, sold as an inexpensive subscription — a strong pick if you want to shape sound, not just level it. Fader is a narrower, keyboard-first per-app volume mixer and router for $19.99 once — a strong pick if speed and a one-time price are what you're after. Match the tool to the job: workstation, or fast mixer.
