Does macOS have a built-in equalizer?

Last updated: October 6, 2026 · By Taha Bozdemir, who builds EQBase

No. macOS has no system-wide equalizer. There is no setting anywhere in System Settings, Sound included, that applies EQ to everything your Mac plays, and Apple has never shipped one. The Music app includes its own 10-band equalizer, but it affects audio played through Music and nothing else. Some individual apps (VLC, Spotify, most media players) ship their own EQ, and each one affects only that app. To get an equalizer on your Mac that covers everything, meaning browser video, calls, games and every other app, you need third-party software that sits between your apps and your speakers. What that asks of you varies: some of these apps install an audio device on your Mac and need your password to do it, while others, EQBase among them, install nothing and simply ask permission to use your Mac's audio.

That's the whole answer. The rest of this page explains each option and why the limitation exists.

What macOS gives you on its own

The Music app equalizer

This is the only graphic equalizer Apple ships on the Mac, and it takes about ten seconds to find:

1. Open the Music app.
2. In the menu bar choose Window, then Equalizer. The keyboard shortcut is Option-Command-E.
3. Switch the equalizer On with the checkbox at the top left of the window.
4. Either pick a named preset from the pop-up menu, or drag the ten sliders by hand. Changes apply immediately, so you can leave a track playing while you adjust.
5. To keep your own settings, choose Manual in the pop-up menu, then Make Preset to name and save the curve.

The sliders run from 32 Hz on the left to 16 kHz on the right, with a separate Preamp slider on the far left. If boosting makes the sound crackle, pull the preamp down a few dB rather than lowering every band.

It's a real equalizer and it's free, with two limits worth knowing: it only affects audio playing through the Music app, so Safari, Spotify, YouTube, games and calls are untouched, and it's a fixed 10-band graphic EQ, so you can't set your own frequencies, bandwidths or filter types.

If all you listen to is your own music library in the Music app, this may genuinely be all you need.

Equalizers built into individual apps

Some apps ship their own. VLC has an equalizer under its audio effects, Spotify's desktop app has one under Settings, Playback (how to use it, and what it can't reach), and most DAWs and media players include EQ of some kind. Each one affects only that app, and each has its own interface, so a change you make in one is invisible to the others.

What macOS does not offer

• No global EQ that applies to all system audio.
• No per-app volume mixer of the kind Windows has had for years.
• No headphone correction for specific headphone models. (Third-party correction curves exist for thousands of them: see headphone EQ settings for Mac.)
• No way to apply a measured correction curve to everything you hear.

Why isn't there one?

macOS routes audio from each app to an output device through Core Audio, and Apple provides no user-facing processing stage in between. Apple has never shipped a global equalizer, and there's no supported setting that adds one.

What Core Audio does allow is for software to step into that path itself, either by publishing its own audio device or by reading the mix your Mac is already playing. Both are supported by Apple, and that is the opening every system-wide equalizer on macOS works through.

How third-party system-wide equalizers work

They all do the same three things:

1. The app gets hold of everything your Mac is playing. Some do this by installing an audio device that appears in your sound settings and becomes your output; others simply read the sound your Mac is already sending out.
2. Every app's audio ends up passing through it, whichever way it got there.
3. It processes that audio (equalization, volume, correction) and passes the result to your real speakers or headphones.

Two things follow from this. First, how step 1 works decides what setup asks of you. Apps that install a device need your password once, and macOS counts capturing the audio back as microphone access, so they ask for that too. Apps that read the sound directly, EQBase among them, ask for one thing instead: permission to use this computer's audio. Second, quality depends entirely on what happens in step 3: whether the processing adds latency, and whether it leaves the signal untouched when you aren't asking it to do anything.

If an app does install a device, a well-built one uses a user-space audio driver rather than a kernel extension, and can be removed completely by its own uninstaller.

What should I look for in a low-latency system-wide Mac equalizer?

Zero added delay on the direct signal by default, a stated figure for anything that does add delay, and output identical to the input when every control is flat. Ordinary minimum-phase EQ filters add no delay; linear-phase filters, lookahead limiters and block-based convolution each add a fixed amount, and every app's capture path and your output device add buffering on top, so a figure that counts only the filters is not the one you hear.

The full checklist, what EQBase adds and the settings for video and games: Mac equalizer latency.

Could system-wide EQ cause clipping, and how should I manage headroom?

Yes: every boost raises the peak level, so on music already mastered close to full scale, a boost can push the peaks past it and clip. Manage it by lowering the overall level by about as much as your largest boost (that is what a preamp is for), by cutting what is too loud rather than boosting what is too quiet, or by letting the equalizer trim itself. A limiter at the end of the chain is the safety net, not the plan.

The Music app's Preamp slider, above, does the first of those. In EQBase, set the equalizer's Preamp yourself or turn on Auto headroom, free on the equalizer, which pulls the whole curve down just enough to keep its highest point at or below 0 dB. It is off by default, so a boost plays at the gain you dialed. Either way the last stage is a safety limiter that steps in only when samples would pass full scale, or when you boost the volume past 100%, and otherwise leaves the audio bit-for-bit untouched, so loud passages are limited instead of hard-clipped. For hot masters, the optional True-peak limiter also holds the peaks between samples below −1 dBTP, at the cost of those 2 ms. The headphone corrections built from AutoEQ already carry a negative preamp for the same reason.

Your options

Which system-wide app to pick is its own question, answered in Mac equalizer apps compared: six of them ranked on EQ depth, with the price, free tier, minimum macOS and Apple silicon or Intel support of each. We've also written honest head-to-heads with eqMac, Boom 3D and SoundSource, including where each of them is the better choice, which for a lot of people they are.

If your problem is specifically that one app is too loud next to another, rather than tone, see per-app volume control on a Mac. If it's that everything is too quiet, see how to make your Mac louder. And if the bass changes depending on where you sit, that's the room, not the Mac; see room correction on a Mac. If the volume keys themselves do nothing, that is a separate fault with its own causes: Mac volume keys not working. And if what you actually want is to capture what you are hearing rather than reshape it, see how to record system audio on a Mac.

Common questions

Can I EQ system audio without installing anything?

You need an app, but not necessarily an audio device on top of it. Some of these apps install one, which is the step that asks for your password. Others, EQBase among them, install nothing extra: you download the app and grant one permission to use your Mac's audio, with no password and no restart.

Does a system-wide equalizer hurt audio quality?

It doesn't have to, but it can, and the difference is entirely in how the software is built. There are three things to check. Transparency when idle: a well-built equalizer is bit-transparent when set flat, meaning the samples that come out are mathematically identical to the ones that went in, not merely close. Latency: a well-built one adds zero samples to the direct signal path, so video stays in sync and calls and games don't lag (what to look for). Clipping: boosts raise the peak level, so it needs headroom management or a limiter to keep loud material clean (how to manage it).

Most products don't state any of this, and a few actively resample or dither everything all the time. If it matters to you, look for one that claims transparency explicitly and lets you verify it while it runs, rather than one that simply doesn't mention it.

Will it work with Bluetooth headphones and AirPods?

Yes. The processing happens before audio reaches the output device, so it works with any output your Mac supports: built-in speakers, USB, HDMI, AirPlay or Bluetooth.

Can I undo it?

Yes. If the app installed an audio device, use its uninstaller rather than just deleting the app, or the device can be left behind. If it installed nothing, dragging the app to the Trash is enough. EQBase is the second kind, unless you turned on one of the two optional features that do install its driver, and those come with an uninstaller.

If you want to try one

EQBase is our take: a full Mac app, with a menu-bar popover for quick changes, that equalizes all system audio, with a free tier that has no time limit, correction profiles for 6,000+ headphone models, zero added latency, and a bit-perfect signal path when everything is flat. It needs macOS 14.4 or later.
