Normalize Audio Online
Measure a clip once and set its volume to a loudness target of -14, -16, -18 or -23 LUFS, or balance every clip in the project in one click. The free plan exports a video file; audio-only downloads need a paid plan.
Normalize Audio Online Features
EchoWave's loudness tools are used by podcasters, YouTubers, course creators and editors who mix voice and music.
Consistent loudness
Normalize audio so every clip plays at the same level
To normalize audio is to measure how loud a clip is and move its volume to a chosen target, so a quiet interview and a loud music bed stop fighting. EchoWave reads the clip once, then sets its volume to the loudness target you pick in LUFS. That is different from a plain volume boost: see increase video volume if you just want louder. Be clear about the output: the free plan exports an MP4 video, and audio-only downloads need a paid plan. Edit sound further in the audio editor.

What you control
The real controls behind Normalize loudness
One card in the clip settings, one switch in the quick volume tool, and a set of limits worth knowing.
-
Named LUFS targets
Pick Auto, -14, -16, -18 or -23 LUFS. Auto aims at -14 for video and voice clips and -18 for music clips. Common habits: -16 for spoken podcasts, -14 for online video, -23 for broadcast-style levels.
-
Balance all clips
Balance all clips measures every audible clip and moves each one to its own automatic target in a single undo step. Muted or hidden clips are left alone, and clips with volume keyframes are skipped.
-
A readout, not a guess
After you press Normalize loudness, the card prints measured loudness and the result, for example from -22.4 to -16.0 LUFS. It says so when the peak limit held the gain back, and when a clip has no audio at all.
-
Instant and undoable
The result is a plain volume change you can see on the volume slider and undo. Because volume plays in the preview exactly as it exports, what you hear is what you get.
-
Quick tool for a single video
The free Change volume tool has a Normalize loudness switch with a target slider from -30 to -6 LUFS, plus volume from 0 to 500 percent and fades. It works on one video at a time.
-
What it will not do
It sets one gain for the whole clip. It does not compress, de-noise or smooth a clip whose own level jumps around, and its peak ceiling is a sample peak, not a true-peak limiter. It makes no broadcast compliance claim.
How it works
How to normalize audio in the editor
Four steps once your clips are on the timeline.
-
Add your clips
Upload the video, voice-over or music files to the timeline. Audio files and videos with sound both work, and you can begin without an account.
-
Select a clip and open Details
Click the clip, open Details and find Normalize loudness in the audio settings. Set each audio clip's role to Voice or Music so Auto picks the right target.
-
Choose a target and press Normalize loudness
Leave Target on Auto or pick -14, -16, -18 or -23 LUFS, then press Normalize loudness. To level the whole project, press Balance all clips instead.
-
Check the readout and export
Read the before and after LUFS in the card, play the clip, and export. The free plan renders MP4 up to 720p with a small EchoWave badge and a short end card.
Who it's for
Who normalizes audio
-
Podcasters
Host and guest recorded on different microphones land at the same level, so listeners are not reaching for the volume between voices.
-
YouTubers mixing voice and music
Set the voice to -14 and the music bed to -18, then add automatic lowering of music under speech if needed.
-
Course creators
Lessons recorded over several sessions stay consistent from one module to the next.
-
Interview and documentary editors
Clips from a phone, a lapel mic and a camera get brought close before the edit.
-
Event and wedding videographers
Speeches, ceremony audio and background music from different devices play at a comparable level.
-
Social clip compilers
A reel built from clips with very different volumes stops jumping from whisper to shout.
Even out the volume of your clips
Upload your clips, pick a LUFS target and normalize, or balance the whole project in one click. The free plan exports a video; audio-only downloads need a paid plan.

Normalize Audio FAQ
How do I normalize audio online?
Add the clip to the EchoWave editor, select it and open Details. In Normalize loudness choose a target and press the button. For several clips press Balance all clips. Then export the project.
Which LUFS target should I choose?
The card offers -14, -16, -18 and -23 LUFS. Many people use -16 for spoken podcasts and -14 for online video. -18 suits a music bed that sits under a voice, and -23 is the European broadcast reference level. Auto chooses between -14 and -18.
Is normalizing the same as making audio louder?
No. Normalizing moves a clip to a target, which can raise or lower it. If you only want more volume, use a boost instead, such as increase video volume. Normalizing is the better choice when clips need to match each other.
Can I download a normalized MP3 or WAV?
The free plan exports an MP4 video. Audio-only downloads such as MP3 or M4A need a paid plan, and WAV and FLAC need a higher one. If a video file is acceptable, the free route works at up to 720p with a small badge.
Does it compress or limit the audio?
No compression. It applies one gain to the clip and holds the result under a -1 dB sample peak. A clip with loud and quiet passages keeps those differences, so use a different tool for evening out within a clip.
Is this broadcast compliant?
We do not claim that. It measures integrated loudness and moves the clip to the target, but it has no true-peak limiter or loudness-range control, so check delivery specs separately when a broadcaster requires them.
Will the preview match the exported file?
Yes for normalizing, because the result is an ordinary volume setting that plays the same way in the preview and the export. You will see it on the clip volume slider.
Why did Balance all clips skip a clip?
Clips that use volume keyframes are skipped so their automation is not overwritten. Muted, disabled or hidden clips are ignored. A clip with no audio is reported as having nothing to normalize.
Normalize audio to a LUFS target
Set clips to -14, -16, -18 or -23 LUFS or balance a whole project. The free plan exports video up to 720p with a small badge.
