A native lightweight macOS app for system-wide parametric EQ. Powered by CamillaDSP.
CamiTune gives macOS a proper system-wide parametric equalizer with an easy-to-use app interface. Each EQ band gives you direct control over its frequency, gain, Q (bandwidth), filter type, and on/off state, with real-time pre-EQ and post-EQ response curve readings.
CamiTune can remember separate settings for each audio device and apply the correct profile automatically when you switch devices.
It’s also ultra-lightweight and designed for minimal system resource usage, with fast and efficient audio processing running quietly in the background without getting in your way.
Set up everything directly inside the app with built-in drivers installation and verification with simple Install / Repair and Recheck options. You can also enable Launch at Login so the app starts automatically when you sign in to macOS.
Create profiles for every audio device, each with its own sound, routing, sample rate, and activation rules. Enable multiple profiles at the same time, rename and organize them freely, and use automatic EQ switching to activate the right profile whenever your audio device or output changes.
Monitor your sound in real time with live input and output level meters, Pre-EQ and Post-EQ spectrum analyzers, and a clear EQ response overlay. Instantly see how your equalizer changes the frequency balance and output of your audio as it plays.
An up to 20-band parametric equalizer with real-time audio visualization and precise control over frequency, gain, Q, preamp, and filter types. See your EQ changes and sound levels update live as you tune. Easily import Equalizer APO .txt presets or paste Equalizer APO configuration text directly to instantly load and edit your settings.
Simply close the app window to hide it in the menu bar and it will continue running in the background. The icon shows your EQ status at a glance — gray when EQ is inactive and yellow when EQ is active. Reopen the app anytime from the menu bar or its Dock icon.
- macOS 13 Ventura or newer.
Intel Mac users can build the app from source, but the current ready-made GitHub download is for Apple silicon. Windows and Linux are not supported.
Open the repository's Releases page and download CamiTune-v0.x.x-app.zip.
Double-click the downloaded ZIP if your Mac did not extract it automatically. Then drag CamiTune.app into your Mac's Applications folder.
The current release is not signed with an Apple Developer ID or notarized, so macOS will probably block its first launch:
- Try to open
CamiTunefrom your Applications folder, then select Done when macOS blocks it. - Open System Settings → Privacy & Security.
- Scroll down to Security and select Open Anyway beside CamiTune.
- Confirm with your password or Touch ID, then select Open.
macOS saves the app as an exception, so you normally need to do this only once.
- In CamiTune, choose Setup in the sidebar.
- Select Install / Repair Everything.
- Enter your administrator password when macOS installs the bundled System Audio Bridge driver.
- Restart your Mac if the app asks you to do so.
- Reopen CamiTune after restarting.
- Select Add Output Profile at the bottom of the sidebar.
- Choose audio devices you want to use.
- Adjust the graphical equalizer, paste an Equalizer APO preset, or import a
.txtpreset. - Leave the sample rate at
48 kHzunless you know your device needs another value. - Save your changes and activate the profile.
Start playback at a low volume. You should see movement in the level meters and live spectrum when everything is working.

CamiTune safely sends your Mac's audio through the equalizer before it reaches your headphones or speakers:
Audio from Mac apps
↓
Selected profile audio device
↓
CamiTune + CamillaDSP
• applies the EQ
• displays the live spectrum
↓
Headphones, speakers, or DAC
When you turn EQ off, CamiTune stops processing and returns audio to the physical output.
- The app will not open: try once, then use System Settings → Privacy & Security → Open Anyway.
- System Audio Bridge is missing after installation: restart your Mac, then reopen CamiTune.
- There is no sound: deactivate the profile, confirm the physical output works normally, then reopen Setup and run Install / Repair Everything.
- The spectrum does not move: run Recheck, confirm System Audio Bridge is installed, and reactivate the profile. Confirm that the app reports it as active.
- The duck menu-bar icon is hidden: your menu bar may be full. Temporarily close another menu-bar app; when the duck appears, hold Command and drag it farther left.
- The app uses lots of resources: when the app window is opened, it needs to calculate the live spectrum graphs, simply close the window app and leave it on the menu bar.
System Audio Bridge is CamiTune's output-only Core Audio driver. When an EQ profile is activated, macOS sends system audio to a virtual output named after that profile. The driver passes the audio to CamiTune, CamillaDSP applies the profile's filters, and the processed result is played through the physical output selected in the profile.
Profile audio devices shown in the macOS output list act as selectors. Choosing one tells CamiTune which profile to activate. The temporary selector is then replaced by the active bridge using the same profile name, which keeps the audio route clear and preserves the normal macOS volume controls.
Only one profile processes system audio at a time. Other checked profiles can remain available in the macOS output list, ready to be selected when needed.
Supported examples:
Preamp: -5.0 dB
Filter 1: ON PK Fc 100 Hz Gain 2.0 dB Q 0.70
Filter 2: ON PEQ Fc 2500 Hz Gain -3.0 dB BW Oct 0.50
Filter 3: ON LS Fc 80 Hz Gain 1.5 dB Q 0.70
Filter 4: ON HS Fc 8000 Hz Gain -2.0 dB Q 0.70
Filter 5: ON HPQ Fc 25 Hz Q 0.70
Filter 6: ON NO Fc 8000 Hz Q 5.00
The graphical editor imports and exports ON and OFF filters. Presets using
BW Oct are converted to the equivalent Q value so they can be edited and
saved without changing the filter response. Supported graphical filter types
are PK/PEQ, LS/LSC, HS/HSC, LP/LPQ, HP/HPQ, NO, and AP.
Device: is recognized but ignored because device selection belongs to CamiTune profiles. Channel: produces a warning because the current release applies filters to both stereo channels.
The complete Equalizer APO language is not supported. This release does not claim support for Include, GraphicEQ, convolution, conditional expressions, processing stages, or arbitrary channel routing.
