About Audio Normalizer
The Audio Normalizer brings a track to a consistent, standards-based loudness using EBU R128 loudness normalization. Instead of just raising the peak, it measures perceived loudness in LUFS and adjusts the whole file to your chosen target — the way streaming platforms and broadcasters level their audio.
Four targets cover the common cases: −14 LUFS for streaming platforms, −16 LUFS for podcasts and speech, −9 LUFS for loud club-style masters, and −23 LUFS for EBU broadcast delivery. A true-peak ceiling of −1, −1.5, or −2 dBTP prevents clipping after normalization.
Upload an MP3, WAV, M4A, or OGG file and download the normalized MP3. The tool is free — the reliable fix for episodes that play at wildly different volumes or files that get turned down by loudness-normalized platforms.
How to use Audio Normalizer
- Upload the file you want to normalize (MP3, WAV, M4A, or OGG).
- Pick a loudness target: streaming −14, podcast −16, loud −9, or broadcast −23 LUFS.
- Choose a true-peak ceiling — −1.5 dBTP is the recommended default.
- Click Normalize and download the normalized MP3.
