Common uses

• Prepare spoken-word audio, video sound, and music for a publishing workflow
• Compare integrated loudness with a destination reference before export
• Listen to a level-adjusted WAV before saving it

Tips

• Use the exact loudness target specified by your broadcaster or publisher when one exists.
• −16 LUFS is a practical web-video starting point, not a universal platform requirement.
• −14 LUFS can help compare against Spotify playback normalization; it is not an upload requirement.
• A −1/−2/−3 dBFS ceiling limits sample peaks and leaves increasing headroom; it does not guarantee a true-peak ceiling.

How it works

1. Select an audio file; it is decoded and analyzed in your browser.
2. Choose a reference target and sample-peak ceiling. Read the target note and estimated gain before preparing.
3. Create the WAV, listen to it in the preview on the right, and download only when satisfied.

Frequently asked questions

Does this prepare a file to meet every platform’s rules?

No. Delivery targets differ and can change. Use the destination’s current specifications; this tool provides reference measurements and a constant-gain WAV.

What does the sample-peak ceiling do?

It reduces the requested gain if decoded sample peaks would exceed the selected dBFS value. It does not calculate inter-sample true peak.

Can I listen before downloading?

Yes. Prepare the WAV first, listen with the player, then use the separate Download prepared WAV link.
