You're deep in a match. Game audio is drowning out your teammates on Discord. You lower the system volume โ now you can hear callouts, but the game sounds are too faint to react to footsteps. Meanwhile Spotify is still playing at full blast underneath everything. macOS gives you one slider for all of it, and gaming on a Mac means constantly riding that slider.
Why gaming audio is uniquely messy on Mac
Games mix multiple audio layers internally โ dialogue, effects, ambient, music โ and output them as a single stream. Voice chat apps like Discord, FaceTime, or TeamSpeak add a second stream. A music player adds a third. macOS treats all of them as equal citizens feeding one master output, with no way to prioritize or balance them against each other.
Most games have internal volume sliders, but adjusting those means alt-tabbing out of a fullscreen game, breaking your flow. And even if you lower the game's internal music, you still can't raise Discord relative to the game's effects without changing the master volume and affecting everything else.
Per-app audio for gaming sessions
SoundDial gives each app its own independent volume slider from the menu bar, so you can set up a gaming audio mix without touching in-game settings or the system slider.
A typical gaming profile
- Game: 70% โ loud enough for spatial audio cues without overwhelming
- Discord / FaceTime: 100% โ teammate callouts always audible
- Spotify / Apple Music: 25% โ background vibes without competing
- Browser: muted โ no surprise tab audio
- Slack / Messages: muted โ zero notification interruptions mid-game
Save this as a "Gaming" profile. One click before you launch, and every app snaps to its gaming level. When you're done, switch back to your normal profile โ no manual slider adjustments needed.
Auto-ducking for voice priority
SoundDial's auto-ducking feature can automatically lower game and music audio whenever Discord or FaceTime is active. Your teammates' voices always cut through, and everything rises back up during quiet moments. It's the same behavior professional broadcasters set up with complex routing tools, but here it's a single toggle.
