Achieve consistent sound levels
or drop, paste, or choose from cloud
Normalize with EBU R128, RMS or Peak, and set the exact target level in LUFS or dB, plus the loudness range and true-peak ceiling.
AAC, AIFF, FLAC, M4A, MP3, OGG, Opus, WAV and WMA are all supported, and you can drop in a full album at once.
The audio normalizer runs in your browser on any device. No download, no sign-up, and every transfer is encrypted.

Normalizing audio means adjusting the volume of audio files to get a consistent, balanced sound. With Audio2Edit's "Normalize Audio" tool, you can easily normalize audio online. Our audio normalizer includes advanced features for formats such as AAC, AIFF, FLAC, M4A, MP3, OGG, Opus, WAV, and WMA.
Whether your audio files have different volume levels or you want to improve their overall sound, this feature helps. Simply upload your audio file, choose the normalization option, and let Audio2Edit do the rest.
Peak normalization finds the single loudest sample in the file and shifts the whole recording so that peak lands on your target level. It is quick and it never changes the dynamics, but two files with the same peak can still feel very different in loudness.
RMS normalization works from the average energy of the recording instead, which is much closer to how loud a track actually sounds. It is the usual choice for music libraries, DJ sets and anything that has to play back evenly one track after another.
EBU R128 measures integrated loudness in LUFS the way broadcasters do, and watches the loudness range and the true peak at the same time. Pick it for podcasts, radio, television and streaming delivery, where a specific loudness standard has to be met.
The target level decides how loud the finished file ends up. The default here is -23 LUFS, the EBU R128 figure used across European radio and television. Podcasts are normally delivered around -16 LUFS, and streaming services level playback to roughly -14 LUFS. Pushing a master louder than that buys nothing.
In EBU mode you can also set the loudness range target. It controls how far the quiet and loud passages are allowed to drift apart, and defaults to 7 LUFS. You can set the maximum true peak in dBTP as well, which defaults to -2.0. Keeping true peak below zero leaves headroom for lossy encoding, where the decoded waveform can overshoot the original samples and clip.
Normalize your audio online with Audio2Edit today.
Yes. You can normalize audio online for free, with no account and nothing to install. A subscription is only worth it if you regularly work with very large files or long recordings.
Normalization changes the level of the recording, not its content, so the adjustment itself costs nothing. Quality only comes into it through the output format. Re-encoding to MP3 or another lossy format loses a little detail. Choose WAV or FLAC if the result has to stay lossless.
Amplifying applies a fixed gain that you choose. Guess low and a quiet file stays too quiet. Guess high and a loud one clips. Normalizing measures the file first, then applies exactly the gain needed to reach your target level. That is why it gives consistent results across a whole set of files.
-23 LUFS is the EBU R128 broadcast target and the default setting. Podcasts are usually delivered at about -16 LUFS and music streaming platforms play back at roughly -14 LUFS. With no specific requirement, -16 LUFS with a true peak of -1 dBTP is a safe all-round choice.
AAC, AIFF, FLAC, M4A, MP3, OGG, Opus, WAV and WMA are all supported. You can keep the original format or pick a different one in the same run, so a normalized WAV can come back as an MP3.
Yes. Add as many files as you need and every one of them is normalized to the same target level. It is the fastest way to even out an album, a lecture series or a batch of interview recordings.
