EarTrumpet is a volume control and audio mixer application for Windows that runs as a system tray utility.
The tool addresses the limitations of Windows's built-in audio management by providing per-application volume control, the ability to route individual apps to different playback devices, and visualization of audio with multi-channel aware peaking. It operates as a standalone mixer that lets users set custom inputs and outputs for specific applications and manage default playback devices, all accessible from the system tray with support for light and dark modes and configurable hotkeys.
EarTrumpet suits Windows users who need fine-grained control over application-level audio routing and mixing rather than system-wide volume adjustment alone. It is particularly valuable for users running multiple audio applications simultaneously or those with complex audio setups involving multiple playback devices. The tool is distributed through the Microsoft Store with automatic updates built in.
The project maintains active development with regular updates and has established multilingual support across more than twenty languages through community translation contributions via a dedicated crowdsourcing platform. The codebase is written in C# using Windows Presentation Foundation for the user interface, indicating a commitment to native Windows platform integration and modern UI patterns.
