Little cross-platform Max app that automatically ducks the music volume when auditing a second sound source. Depends on BlackHole (macOS), ASIO Link Pro Tool (Windows), or any similar internal audio re-routing tool.

The app is designed to let you listen to music and auto-duck the music volume when another soundsource of your choice is played.

If you want to use your own setup, the app is designed to accept:

• Music - inputs 1 and 2
• Other Audio - inputs 3 and 4
• Output - outputs 1 and 2

If you're able to reroute sound this way yourself, the app will work. If you need setup guidance, check the Wiki.

• Auto music ducking when second soundsource is active
• Control of the release time to avoid quick "on/off" effect (default is set to 5 seconds)
• Quick access to audio drivers, inputs and outputs
