Starts BeyondATC and sets Output Device:

1. Download BeyondAudio.exe
2. Run
3. Select the Device you want to use for BeyondATC & and hit Save!
4. Use the BeyondATC (BeyondAudio) Link on your Desktop to Start BeyondATC
5. You can delete the downloaded Binary (BeyondAudio.exe) after that, if you like
   

Some Notes:

• BeyondAudio only queries active & connected Devices
• The Installation-Location is %appdata%\BeyondAudio
• To Remove: Just delete the BeyondAudio Folder in %appdata%
• To reset/change the Configuration: Run the Application outside of the AppData Folder (i.e. the downloaded Binary) -OR- delete the File %appdata%\BeyondAudio\Device.json
  

Technical Background:
All BeyondAudio does is really just starting BeyondATC (it reads the Installation Path from the Registry) and after that switching its Output-Device in the Windows Sound-Mixer (to the configured Device). So it does automatically what the User can already do manually (every Time BeyondATC is started).
The Device Switch is done via an COM Interface of Windows which was discovered/reverse-engineered by the Creators of EarTrumpet. The CoreAudio Package also implemented that COM Interface - so after all the Abstraction by that Package, the Device Switch is really just a simple Function-Call.
