In my test folder one file measures -30.2 LUFS and another -8.91 LUFS. I run a video editing studio where every delivery is checked against a loudness target, and fixing a whole folder at once is a good job for PowerShell.</p> <p>This article builds <code>Invoke-LoudnessNormalization</code>, an advanced function that measures every video in a folder, normalizes the ones that miss the target, and returns a before-and-after table. It parses ffprobe JSON with <code>ConvertFrom-Json</code>, runs FFmpeg&rsquo;s two-pass <code>loudnorm</code> inside <code>ForEach-Object -Parallel</code>, and supports <code>-WhatIf</code>.</p>
