Audio Deck saves named profiles that each pin a default output and input device, then switches your system to a profile in one click, one command or one Stream Deck button. Profiles live in a local JSON file. No account, no cloud, no background service.
Quick Switch: pick a profile and press Switch in the header tray. Offline devices are marked and applied automatically when they reconnect as the same device.
Create and edit profiles on the Configuration view. The actions live as icons in the header tray and swap with the active view: new, edit, delete, save and cancel. Name the profile, pick an output device and an input device from the live dropdowns, then save.
Configuration: the tray action icons above the saved profiles and the profile editor.
Free and open source. On Windows and Linux it installs per user with no administrator rights.
Audio Deck is free and stays free. There is no paid tier, no licence key and no feature held back behind a donation. If it has replaced something you were paying for or simply saved you an afternoon, a contribution supports its maintenance and continued development. The same button sits in the window's own header.
