Reference tracks at the volume you set them at.
mactooloud keeps Logic, Ableton, and Spotify exactly where you put them while silencing the macOS notification chorus. No more accidentally clipping your monitors because Slack pinged at full gain.
Why this gets in your way today.
System sounds blow out the monitors
You're A/B'ing a mix at a careful 75 dB and a Slack notification fires at 100%. Your tweeters do not forgive.
Browser ads steal your reference
You open a reference track on YouTube. A pre-roll ad comes in at twice the loudness. Mix ruined.
Discord and your DAW share one slider
Talking to a co-producer while reviewing a stem means choosing between hearing them and hearing the track.
How mactooloud handles it.
Per-app volume mixer
Lock Logic at 100%, drop Slack to 20%, mute Chrome ads at the source. Settings persist across reboots.
Per-app device routing
Send Logic to your monitors, Discord to your headphones. Talk to a collaborator while the mix plays out loud.
Mystery Sound Finder
When a stray YouTube tab interrupts your reference loop, you'll know which one in three seconds.
Whisper Mode
Print the master, then tap Whisper to silence everything for an instant before bouncing.
Set it once. The monitors stay safe.
Lock the apps that should never blow past their settings. mactooloud holds every locked app at the level you chose — even when macOS forgets.
Set up your mix in under a minute.
