Pilots on VATSIM can be super quiet or blaringly loud in vPilot/xPilot. This app sits between those clients and your ears, normalising their audio in real time so every transmission lands at the level you choose - no more chasing volumes with every transmission!

Pick the source device (where vPilot/xPilot outputs), pick your playback device, set a target loudness.
Built-in brickwall limiter prevents blasts; a tiny, configurable delay applies perfect normalisation.
Remembers your settings and devices.
No drivers or virtual cables—uses Windows WASAPI loopback.

For the top dropdown menu, this MUST be the same as your vPilot output device. You MUST ensure this is a device that does not route to your headset. It must be a device that is not monitored. This ensures vPilot is outputting properly but you cannot hear the raw audio.

The second dropdown is now for you to select your headset audio device.

Please Provide Feedback!

I have created this just to fix my own issues with sporadic pilot/atc volumes on VATSIM, so if you have any suggestions or issues, please reach out. I'll be more than happy to take a look. :)
