How to use Audio Normalizer
Add audio files
Drop one or many MP3, WAV, OGG or M4A files. Each one is measured at once.
Choose a target
−14 LUFS suits Spotify, YouTube and most streaming. −16 suits podcasts, −23 suits broadcast. Or set your own.
Check the gain
You see how loud each file is now and how many dB it will change. Keep Prevent clipping on so loud peaks stay clean.
Normalize and download
Save as MP3 or WAV. Several files download together as a ZIP.
Frequently asked questions
What is the difference between normalizing and boosting volume?
Boosting multiplies the level by a number you choose. Normalizing measures how loud the file really sounds (LUFS) and changes it by exactly the amount needed to reach a target, so many files end up equally loud.
What is LUFS?
Loudness Units relative to Full Scale: a measure of perceived loudness defined by ITU-R BS.1770 and EBU R128. Streaming services use it to level tracks.
Which target should I choose?
−14 LUFS for music and video on streaming platforms, −16 LUFS for podcasts, −23 LUFS for European broadcast.
Will it distort my audio?
Turning audio up can push peaks over 0 dBFS. With Prevent clipping on, a short look-ahead limiter holds the peaks at −1 dBFS.
Is my audio uploaded?
No. Measuring and processing happen in your browser and your files never leave your device.
