Normalize audio volume
A recording that's too quiet makes people turn it off. Frameloom measures your audio's loudness the way streaming platforms do (EBU R128) and brings it to the level they expect, in two passes so it's accurate and doesn't clip. The video isn't re-encoded.
Free to try: a 10-minute video costs 4 tokens, and you get 30 every week.
How to do it
- Open Normalize loudness and drop your file in, or pick it from your device. It stays on your device.
- Check the settings. −14 LUFS suits YouTube and Spotify. Pick −16 for podcasts or −23 for broadcast.
- Press Run, then preview and download the result.
What “loudness normalization” does
Platforms measure loudness in LUFS, which is closer to how loud people perceive sound than the peak level is. The first pass measures your file, and the second applies exactly the gain needed to reach the target, with a true-peak limit of −1.5 dBTP so nothing distorts.
It uses linear gain, so the natural dynamics of your recording are kept. Quiet parts stay quieter than loud parts; the whole thing is just at the right level.
Questions
- Which target should I use?
- −14 LUFS for YouTube, Spotify and most social platforms, −16 LUFS for podcasts, and −23 LUFS for European broadcast (EBU R128).
- Does it work on audio-only files?
- Yes. MP3, WAV, M4A and other audio files are supported; the result is an M4A.
- Is the video re-encoded?
- No. The picture is copied untouched and only the audio is processed.
