Normalize Audio for Facebook
Facebook normalizes all audio to -14 LUFS before it reaches listeners. If your track is louder than -14 LUFS, the platform turns it down. If it's quieter, it may be turned up. LoudFix measures your audio using the same ITU-R BS.1770-4 algorithm and applies a linear gain adjustment to hit the target exactly — no compression, no dynamic range loss.

How to Normalize Audio for Facebook
- 01
Upload your audio
Drop your WAV, MP3, FLAC, or other audio file onto LoudFix. Batch up to 15 files at once.
- 02

Download and upload to Facebook
Download the normalized file and upload it directly to Facebook. No further volume adjustments will be applied.
When you upload audio to Facebook, their loudness normalization system adjusts your track's volume before it reaches listeners. Preparing your audio to the -14 LUFS standard ensures your music, podcast, or video sounds exactly as you intended — no unexpected volume changes, no quality surprises after upload.
Frequently Asked Questions
- What LUFS does Facebook use?
- Facebook targets -14 LUFS integrated loudness with a -1 dBTP true peak limit, following the ITU-R BS.1770-4 standard.
- Will Facebook change my audio's volume?
- Yes. Facebook normalizes all tracks to -14 LUFS. Tracks louder than this are turned down; quieter tracks may be turned up depending on the platform.
- Does normalizing audio affect quality?
- LoudFix applies a linear gain adjustment only — no compression, no limiting. Your dynamic range is fully preserved. The only quality impact is if you choose a lossy output format like MP3 or AAC.
- Can I normalize multiple files at once?
- Yes. LoudFix supports up to 15 files in a single batch. Drop them all at once, select the Facebook preset, and download all results.
- Is my audio uploaded to a server?
- No. LoudFix processes everything in your browser using WebAssembly (FFmpeg). Your files never leave your device.
