Mac Sound settings vs the Windows Volume Mixer: what's actually different

The one real difference is scope. The Windows Volume Mixer is a per-app mixer — a slider (and, in Windows 11, an output and input device) for every app currently making sound. The macOS Sound panel is a single-output panel: one master volume, one output device, and one balance for the entire machine. Everything else — switching devices, setting input levels, tuning alert volume — both do. Per-app control is the one thing the Mac panel leaves out.

If you're moving between the two platforms, this trips people up because the panels look like they do the same job. They don't. Windows built a mixer; macOS built a master control. Below is what each panel actually contains, control for control, so you know exactly which feature you're looking for and where it does — or doesn't — exist.

What the Windows Volume Mixer actually is

In Windows 11, the Volume Mixer lives at Settings → System → Sound → Volume mixer. You can also open it with Ctrl + Windows + V, or by right-clicking the speaker icon in the taskbar. It's a list, and the list is the point: every app that has recently played sound gets its own row.

Each row carries a volume slider, so you can leave a game at 100% while a browser sits at 20%. In the redesigned Windows 11 mixer, each row also has an output and input device dropdown, so a single app can be pointed at a different speaker or headset than everything else. There's a master slider at the top for overall system volume, plus a mono toggle and audio enhancements. One caveat that catches people: an app only appears once it has actually played (or recorded) audio — silent apps aren't in the list. Windows saves each app's choices and reuses them next time.

What macOS Sound settings actually give you

On a Mac, open System Settings → Sound. It's organized around the whole machine, not around apps. At the top is the master output volume slider and a mute checkbox — the same level your volume keys move. Below that you pick a single output device from a list (built-in speakers, headphones, an external interface), and there's a balance slider for left/right.

The Input section mirrors it: choose one input device and set its input level. Then a Sound Effects section handles the alert volume — the level for system alerts and notification sounds — along with which alert sound plays, which device plays it, and toggles for interface sound effects. Alert volume is relative to the master output, so turning the system down quiets alerts too. For aggregate or multi-output devices you'd open the separate Audio MIDI Setup app. What you will not find anywhere in here is a per-app slider.

Side by side: control for control

Laid out next to each other, the two panels overlap on almost everything except the feature the Volume Mixer is named after.

Read down the last two rows and you have the whole story. The Mac panel actually does a couple of things the mixer doesn't — a true balance slider, one clean alert-volume control — but it treats audio as one stream. Windows treats audio as a stack of app streams you can address individually.

The one difference that matters: per-app vs one master

This isn't a cosmetic gap. On Windows, "make the call louder than the music" is one drag in one panel. On a Mac, there's no equivalent surface — the Sound panel only knows the master level, so turning down the system to take a call ducks everything at once. Your options are to lean on each app's own internal volume slider (fine for a Spotify or a browser, useless for apps that have none, and scattered across a dozen windows) or to add the missing layer with software. There's a fuller walk-through in does the Mac have a volume mixer like Windows?, and a switcher's checklist of the exact controls you'll miss in the volume controls you'll miss coming from Windows.

Worth saying plainly: this is a missing feature, not a broken Mac. macOS routes everything through one master output by design, and it's genuinely good at the parts it covers. It just never shipped the per-app column that makes the Volume Mixer a mixer.

How to add the mixer's missing column to a Mac

You get the per-app column back with a third-party app that sits at the audio layer and gives every running app its own level. A few worth knowing, honestly compared:

They all give you the sliders the Sound panel lacks. Background Music is free and open source and a solid answer if you want per-app levels at no cost. SoundSource is the deep, feature-rich option with per-app EQ and effects. Fader's angle is speed and price: it's the closest thing to the reflex of right-clicking the taskbar speaker on Windows, except it lives on your keyboard. You hit a toggle hotkey and letter keys become faders — one column per app — so "call up, music down" is a couple of keystrokes without ever opening a panel. It's $19.99 one-time (no subscription), with a 3-day free trial, on macOS 14.4 or later.

Bottom line

The Windows Volume Mixer and the macOS Sound panel cover the same ground — master volume, device selection, input levels — right up to the feature the mixer is built around. Windows gives every app its own slider; the Mac Sound panel gives you one master and stops there. If per-app control is what you came from Windows expecting, macOS doesn't ship it, but a small app restores it. And if reaching that control fast matters as much as having it, that's the exact gap Fader is built to close.
