VATSIM Audio Normalizer

VATSIM Audio Normalizer keeps every radio transmission at the same comfortable level. It also fixes the nasty bug where the VATSIM audio becomes super duper loud.

Features

• Catches sudden loud transmissions before they reach your ears (look-ahead limiter)
• Lifts quiet stations to the same level as everyone else
• Smooth, natural sound: no pumping, crackle or choppy audio
• Live output meter so you can see it working
• Bypass switch to compare with the raw audio
• Start with Windows and run quietly in the system tray
• Resizable window with a compact layout
• Built-in logs and a one-click diagnostic report for support

How it works

Your pilot client plays into a spare sound device that you don't listen to. The app captures that audio, evens out the loudness, and plays the result into your headset.

Setup (about 2 minutes)

1. Pick a spare playback device: monitor/HDMI speakers, the motherboard speaker jack (nothing needs to be plugged in), or the free VB-CABLE virtual audio cable.
2. In vPilot → Settings → Audio, set the speaker/output device to that spare device. Leave your microphone as it is. (xPilot, TrackAudio and Swift work the same way.)
3. Run VATSIMAudioNormalizer.exe. Set "Pilot client plays into" to the spare device and "Your headset" to what you listen on.
4. Press Start Normalization.

Full instructions are in README.txt inside the download, and under Help in the app.

Requirements

• Windows 10 or 11 (64-bit)
• A spare playback device, or the free VB-CABLE virtual audio cable

Good to know

• Windows may show "Windows protected your PC" the first time, because the app isn't code-signed. Click More info → Run anyway.
• Too soft even at full Loudness and Volume? Turn up your headset's own volume in Windows.
• Only audio sent to the spare device is processed. Your sim and other apps are untouched.
