How to control Spotify's volume separately on Mac

Yes — Spotify is one of the easy cases. Its Mac desktop app has its own volume slider in the bottom-right of the now-playing bar, and that slider changes only Spotify's output: your system volume, your calls, and every other app stay exactly where they are. That covers the simple need. Where it stops is when you want to nudge Spotify from your keyboard without leaving what you're doing, or balance it against an app that has no slider of its own — and that's where a per-app mixer comes in.

This trips people up because Spotify's slider behaves nothing like the Mac's own volume keys. The keys on your keyboard move one master output that sits in front of every app, so tapping them quiets music, Zoom, and notification sounds together. Spotify's in-app slider is the opposite: it's an app-level control that touches Spotify and nothing else. Knowing which of those two you're reaching for is most of the battle.

The quick answer: Spotify's own volume slider (free)

Look at the bottom-right corner of the Spotify window, next to the queue and device icons. The small speaker with a horizontal bar is Spotify's volume. Drag it down and only Spotify gets quieter — a podcast in your browser, a call, or a game keep playing at their level. You can also click the speaker to mute Spotify outright. It's built in, it's free, and for "make Spotify a bit quieter right now" it's all most people need.

One thing that surprises people: the F-row media keys and the play/pause controls on a Mac keyboard don't touch this. They send transport commands — play, pause, next, previous — not a fine volume change. So there's no built-in keyboard way to ride Spotify's own level; you have to click into the window and drag. Keep that in mind, because it's exactly the gap the rest of this guide is about.

Where Spotify's built-in slider stops being enough

The slider is fine for one app in isolation. It starts to feel thin the moment your day involves more than Spotify:

• It needs the Spotify window. To change the level you have to switch to Spotify, find the slider, and drag. If you're deep in a call or an editor, that's a context switch every time the mix changes.
• There's no global hotkey. macOS won't let you bind a key that lowers Spotify from inside another app. The built-in slider is mouse-only.
• It only helps Spotify. If the app you're trying to balance against — a game, a system alert, some Electron app — has no slider of its own, Spotify's control can't help you there. You're back to riding the master volume, which drags everything with it.
• It doesn't remember a mix. Set Spotify to sit under your calls, quit for the day, and tomorrow you're setting it again by hand.

None of that is a knock on Spotify — an app slider is an app slider. It's just that "Spotify quieter than everything else, reachable in a keystroke, and it stays that way" is a system-level job, and no single app can do it alone.

The system-wide way: a per-app volume mixer

A per-app mixer sits at the macOS audio layer and gives every running app — Spotify included — its own level in one place. That's the piece macOS never shipped. With one of these, Spotify becomes just another channel you can set, save, and reach without hunting for its window. Your options span free to paid:

Background Music is free and open source and will absolutely give Spotify its own level from a menu-bar list — a genuinely good choice if free is the priority and you don't mind a menu-bar workflow. SoundSource, from Rogue Amoeba, is a polished paid tool with per-app volume plus EQ and effects at $49 one-time. Fader is the keyboard-first option at $19.99 one-time. They all set Spotify's level; the real difference is how fast you can reach it.

Why keyboard control matters for a music app you nudge all day

Spotify isn't an app you set once. You duck it when a call comes in, push it back up when the call ends, drop it when you need to focus, mute it when someone walks over. Every one of those, with a menu-bar list or the built-in slider, is the same little chore: leave what you're doing, find the control, drag, come back.

Fader's bet is that the fastest controller you already own is your keyboard. You hit a toggle hotkey, the keyboard becomes a mixer — on the landing page's default layout, the W/S/X column is Spotify — and you ride its level with letter keys without ever leaving your call, your editor, or your game. Set Spotify to sit under your voice once, save it as a profile, and it comes back that way. For the one app you touch more than any other in a working day, that's the difference between "I have a mixer installed" and "I actually use it."

How to mute Spotify instantly from anywhere

Muting Spotify the instant a call connects is the most common ask. Spotify's own speaker icon mutes it for free — if you're already in the window. To mute it from inside any other app, with no window switch, you need a per-app mute key, and macOS doesn't offer one natively. In Fader you assign a mute key to Spotify's channel, so "kill the music" is a single keystroke whether you're in Zoom, a browser, or full-screen anything. If a global mute hotkey is really all you're after, our guide to setting a keyboard shortcut to mute an app on Mac walks through the whole setup.

Related: sending Spotify to a different output

Volume's close cousin is output routing — sending Spotify to one device while everything else plays somewhere else. Music to desk speakers, calls to a headset, for instance. macOS sets a single output for everything, so per-app routing also needs a third-party tool. If that's the actual problem you're solving, read how to send one app's audio to a different output on Mac.

Bottom line

For a quick, one-off change, Spotify's built-in slider already lets you set its volume separately on a Mac — it's free and it only touches Spotify. The moment you want to control it from your keyboard without opening the window, balance it against apps that have no slider, or save a mix that survives a restart, that's a system-level job for a per-app mixer. Background Music does it for free from the menu bar; if reaching Spotify's level in a single keystroke is what you care about, that's exactly what Fader is built for.
