Best volume mixer for Mac for remote workers
If your workday is back-to-back calls, a volume mixer is mostly about one thing: hearing people clearly while Slack pings and music stay out of the way. Here's what to get.
Short answer
- Best overall for calls: Faders. It ducks other apps during calls automatically, keeps AirPods in high quality while you talk, and mutes every mic with one shortcut. $5.99 at launch.
- Best if you also want an EQ: SoundDial. It has call ducking too, plus a 10-band EQ and volume profiles, for $12.99 on the Mac App Store.
- Best if you need the full toolkit: SoundSource. A system-wide mic mute, EQ, effects and AirPlay, for $49. We couldn't find automatic call ducking in it.
What remote workers actually need
- Music that gets out of the way by itself. When a call starts, other apps should fade down. When it ends, they should come back. You shouldn't have to remember to do it.
- Notifications quieter than people. Slack and email pings at a lower level than the call.
- A mute you can trust. One shortcut that mutes your mic in every app, not just the one in front.
- Headphones that sound right. If you use AirPods, macOS drops them into a muffled call mode whenever their mic is in use. That's fixable.
- The right devices. Calls on your headset, and macOS not switching to your monitor's speakers on its own.
The picks
Faders
$5.99 once at launch ($15.99 regular) · macOS 14.2+ · No trial (browser demo) · fadersmac.com
Faders was built around calls. When Zoom, Teams, Meet, FaceTime, Slack or Discord uses your mic, other apps fade down and come back when the call ends. When Bluetooth headphones connect, it keeps the Mac's built-in mic in use, so AirPods stay at 48 kHz stereo instead of switching to call mode. ⌃⌥⌘M mutes every physical mic and puts each one back the way it was. You can also rank devices so calls go to your headset and macOS never picks your monitor's speakers.
Good
- Automatic call ducking
- Keeps AirPods high-quality on calls
- Global mic mute
- Device priority rules
- 0.0 % CPU when idle
Not so good
- No equalizer yet
- No profiles or presets
- No free trial, sales are final
- New app from one developer
SoundDial
$12.99 once (Mac App Store, Family Sharing) · macOS 14.2+ · eduardbruch.com/sounddial
SoundDial is the closest match to Faders for calls. It ducks other apps during calls in Zoom, Teams, FaceTime, Webex, Slack, Discord, Skype, WhatsApp, Telegram and browsers, and adds things Faders doesn't have: a 10-band EQ and volume profiles like “Work” and “Focus”. We couldn't find a global mic mute, device priority rules or AirPods mic handling in its listing.
Good
- Call ducking
- 10-band EQ and profiles
- Mac App Store, Family Sharing
Not so good
- Global mic mute: not listed
- Device priority: not listed
- AirPods call quality: not listed
SoundSource 6
$49 once · Free trial · macOS 15+ · rogueamoeba.com
SoundSource has a system-wide “cough button” mic mute, settings you can lock so call apps can't change them, a preferred device order, EQ and Audio Unit effects. It's the most capable app here. For calls specifically, we couldn't find automatic ducking or the AirPods mic fix. If you want those, Faders or SoundDial fit better, and they cost less.
Good
- Mic mute and locked settings
- EQ and effects
- Free trial, established company
Not so good
- $49
- Needs macOS 15
- Call ducking: not listed
FineTune
Free, open source · macOS 15+ · GitHub
FineTune gives you per-app volume, EQ and device priority for free. It doesn't list call ducking or a global mic mute, so you'd still turn music down by hand when a call starts. If money is tight and you're on macOS 15, start here.
Good
- Free
- EQ, routing, device priority
Not so good
- Call ducking: not listed
- No paid support

Free things to try first
- Pick your mic by hand. In System Settings → Sound → Input, choose your Mac's built-in mic while using AirPods. Your headphones stay in high quality. (macOS may switch back the next time they connect. Faders does this for you automatically.)
- Turn down notification sounds. Slack and most chat apps have their own notification volume or sound settings.
- Mute from the call app. Zoom, Teams and Meet all have their own mute shortcut. It just only works in that one app.
Questions
Which call apps does Faders detect?
Zoom, Teams, FaceTime, Google Meet, Slack and Discord, among others. It notices when one of them is using the mic and ducks the other apps.
Will per-app volume add delay to my calls?
Only apps you actually adjust pass through Faders, and those get about 60 ms of extra latency. That's a limit of Apple's audio system and is the same for every tap-based app. Leave your call app at 100 % and it isn't touched at all.
Can I control the volume of one browser tab, like a Meet tab?
No app can. Browsers play every tab through one audio process, so you control the whole browser.
Make calls the loudest thing on your Mac
Faders is $5.99 once at launch. Try the live demo first: press “Start a call” and watch the music duck.
