Overview
Choose a loudness target for your recording and save an audio copy. If you start with a video, you’ll get audio from it, not a new video.
Choose a loudness target
Upload one MP3, WAV, M4A, AAC, OGG or FLAC recording, or an MP4, MOV, MKV or WebM video, up to 500 MB. Device limits may require cloud processing for a file below that upload limit.
Choose Loudness Target under Options. Loudness Units relative to Full Scale (LUFS) describe overall perceived loudness. If someone has given you a delivery specification, start with the target they ask for.
| Preset | Target |
|---|---|
| Standard (default) | -16 LUFS |
| Podcast | -16 LUFS, loudness range (LRA) 8 |
| Broadcast | -24 LUFS |
| Streaming | -14 LUFS |
| YouTube | -13 LUFS |
| Apple Music | -16 LUFS |
To use a loudness preset on its own, leave the other sound controls unchanged and keep Format at mp3. Combining other adjustments with a target can change how the preset is applied.
Process and check the result
Click Process Normalize Audio, then save the result with Download. An automatic download may start after five seconds.
Listen to a quiet passage and a loud one. If you need to meet a delivery specification, measure the downloaded file before sending it. The preset name alone doesn’t confirm that your file meets every requirement.
Keep the original video separately if you’ll need its pictures later.

Examples & use cases
An editor preparing an audio delivery
Bring a spoken recording toward a target
A spoken recording needs a consistent loudness target for delivery.
One supported audio file up to 500 MB to Audio copy
- Choose Standard (-16 LUFS), or the delivery target requested for your project.
- Leave other sound controls unchanged and Format at mp3 for the preset workflow.
- Process, download, and listen to quiet and loud passages.
Expected outcome
Measure the downloaded file when compliance with a delivery specification matters.
An editor preparing an audio delivery
Make an audio copy from a recorded talk
You want audio from a video at a selected loudness target.
MP4 with audio to Audio copy without the video pictures
- Add the video and choose the requested Loudness Target.
- Process Normalize Audio and download the result.
- Listen through the recording and keep the original video separately.
Expected outcome
This workflow produces audio; it does not deliver a normalized video.
Access & cost
Check the access shown after selecting your file. A guest task may be available for eligible on-device processing. Cloud processing requires sign-in and uses credits; local allowances depend on your account.
Privacy
Check the processing mode before starting. Online processing uploads files; completed results may remain available for later download. See the Privacy Policy for current handling and retention details.
Questions about Normalize Audio
Will normalization remove background noise?
No. Normalization adjusts loudness; it does not identify and remove unwanted background sound. Noise may become more noticeable when the recording is raised in level. Clean up noise separately and listen again after normalization.
Can I normalize a group of recordings at once?
No. This workspace processes one file at a time. Use the same target for each recording and compare the saved results.
