Headphones for a call. Speakers for a film. A shortcut for everything in between.
Smart Audio Switcher is a Windows tray app for switching audio outputs, controlling media and muting the microphone. Give each device a name and a hotkey, or let a scenario choose the output when you move between applications.

Actual WPF interface, rendered with example devices and scenarios. The current app interface is in Russian.
| Your devices | Your applications | Your controls |
|---|---|---|
| Keep headphones, speakers and other outputs in one list. Assign a name and shortcut to each. | Pick an application and the output it should use while it is in the foreground. Enable speaker fallback if you want it. | Mute the microphone, change volume and control playback without opening the main window. |
- Reconnect without rebuilding your setup. Saved hardware identity helps recover device bindings when Windows recreates an audio endpoint, provided the match is unambiguous.
- A reminder when you mute. An optional small overlay appears when you mute the microphone using the app's shortcut. It does not track mute changes made by other applications.
- Keep it in the tray. Choose startup and window-closing behavior, notifications and the overlay in settings.
- Get update prompts. The app checks GitHub at startup; a manual check is also available in the tray menu and settings.
Both builds are for Windows x64. The current release targets Windows 10/11.
| Download from Releases | What you need |
|---|---|
SmartAudioSwitcher_Full.exe |
The .NET runtime is included. Choose this if you are unsure which build to use. |
SmartAudioSwitcher.exe — Light |
Install .NET 8 Desktop Runtime, x64 first. The app download is smaller. |
Run the EXE directly; there is no installer. Settings are stored in %APPDATA%\SmartAudioSwitcher\settings.json, so moving the EXE alone does not move your configuration. To update manually, close the running app before replacing its EXE.
- Open the app and choose the actual Windows output in each device card. Rename the cards if you like.
- Click a shortcut button and press your preferred key combination. The initial headphones and speakers shortcuts are
Alt + HandAlt + S. - To create a scenario, open the target application, select it in Сценарии (Автосмена), choose an output and click +. Scenario switching follows the foreground application; it changes the Windows default output, not a separate per-app audio mixer route.
- Enable Автовозврат на колонки if you want to return to the speakers when leaving a matching scenario. This uses the second managed device card.
| Action | Shortcut |
|---|---|
| Headphones / speakers | Alt + H / Alt + S |
| Mute / unmute microphone | Alt + M |
| Volume up / down | Ctrl + ↑ / Ctrl + ↓ |
| Previous / next track | Ctrl + ← / Ctrl + → |
| Play / pause | Alt + P |
All of these can be reassigned. If Windows or another application already reserves a combination, choose a different one.
- If an older saved device disappears before its hardware identity has been recorded, you may need to select its replacement once. Ambiguous matches are not guessed.
- A settings backup is kept when a valid configuration is replaced. Diagnostic logs are stored in the application's AppData directory.
- The app currently has a Russian UI. Both English and Russian documentation are maintained here.
Built with C# / .NET 8, WPF, Windows Core Audio COM and Hardcodet.NotifyIcon.Wpf.
Build, run and check the project
Use Windows x64 and the .NET 8 SDK. From the repository root:
dotnet run --project SmartAudioSwitcherTo build the two release variants, run these commands inside the application project directory:
cd SmartAudioSwitcher
dotnet publish -c Release -r win-x64 --self-contained false -p:PublishSingleFile=true -p:EnableCompressionInSingleFile=false -o bin\Publish\Light_SingleFile
dotnet publish -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -o bin\Publish\Full_SelfContainedBoth commands produce SmartAudioSwitcher.exe in their respective output directories. For a release, the Full file is distributed as SmartAudioSwitcher_Full.exe.
From the repository root, run the regression checks and an isolated rendering check:
dotnet run --project SmartAudioSwitcher.Tests -c Release -- --renderThis command checks the test fixtures and renders XAML without switching your real audio devices. The additional hardware-switching test flags are for deliberate manual validation, not a routine build step.
To refresh the README images from the current XAML with example data:
dotnet run --project tools/ReadmeScreenshots -c Release -- .Found a switching problem? Open an issue with the app version, Windows version, output-device names and steps to reproduce it. Check diagnostic logs for personal information before attaching them.
