EarTrumpet is a Windows Presentation Foundation (WPF) app consisting of a notification area icon with a context menu, flyout and a volume mixer window. Changing the default device is available on the context menu. Hotkeys can be assigned in settings to invoke the flyout, volume mixer or open settings. The flyout and volume mixer have effectively the same controls, in both cases there is a hidden popup on each app session (type space or right click) that reveal sliders for each item in the app group (e.g. multiple Firefox sessions running).

EarTrumpet uses the Windows Multimedia Device API to replace the system volume experience, enabling richer control of apps and devices through a modern UI with independent app controls.

The volume mixer and settings windows are single-instance and created on demand.
