Normalize Audio for Podcast — -16 LUFS Free

Podcast platforms automatically normalize audio to a standard loudness level. If your episode is too quiet or too loud, the platform will adjust it — often with poor results. Normalizing to -16 LUFS before uploading ensures your podcast sounds exactly as intended on every platform.

Podcast loudness standards by platform:

We recommend -16 LUFS as the universal podcast standard — it satisfies Apple Podcasts requirements and is close enough to Spotify's -14 LUFS that the difference is imperceptible.

Normalizing your podcast audio takes just a few steps:

1. Export your episode from your DAW or recording software as WAV or MP3.
2. Drop the file onto the normalizer above.
3. Set the target to -16 LUFS (the Apple Podcasts standard).
4. Click Normalize — processing happens locally in your browser.
5. Download the normalized file and upload to your podcast host.

The entire process takes under 30 seconds for a typical 30-minute episode.

LUFS (Loudness Units relative to Full Scale) is the international standard for measuring perceived audio loudness. Unlike peak level (dBFS), LUFS measures how loud audio actually sounds to human ears — accounting for the way we perceive different frequencies.

Why LUFS matters for podcasters:

• Consistency: Every episode sounds the same volume to listeners
• Platform compliance: Avoid automatic volume adjustments that can degrade quality
• Professional quality: Listeners expect consistent loudness — it signals production quality
• Accessibility: Consistent loudness is important for listeners with hearing difficulties
