I Replaced My Custom Mac App Audio Routing Solution with Elgato Wave Link 3 and Love It
02/04/2026macOS has always lacked a built-in way to route and mix audio on a per-application basis. Windows users have had per-app volume control for years, but on macOS, you need third-party tools to get anything close. I had been using a combination of SoundDesk, the Stream Deck MIDI plugin, and a Stream Deck plus with dials to solve this. The setup worked, but configuring it was fiddly. Then Elgato released Wave Link 3, and everything changed.
