How to normalize audio volume

📈

1. Load & analyze

Drop in your audio — the tool measures its current peak and average (RMS) loudness instantly.

🎯

2. Pick a target

Peak mode raises the loudest point to a set level. Loudness mode matches average level, great for voice.

3. Compare & export

A/B the original and normalized versions, then download MP3 or WAV.

Normalizing fixes the classic problems: a voice memo recorded too far from the mic, podcast guests at different volumes, or a track that is quiet next to everything else in a playlist. Peak normalization is transparent (it only scales), while loudness mode targets the average level and gently limits peaks to prevent clipping. Trim first with the Audio Cutter, remove dead air with the Silence Remover, or convert formats with the Audio Converter.

Audio normalizer FAQ

What is the difference between peak and loudness normalization?

Peak normalization scales the file so its single loudest sample hits your target (like -1 dBFS) — nothing else changes. Loudness (RMS) normalization matches the average level instead, which is what your ears perceive, and is the right choice for speech and podcasts.

What target should I use?

For a final master, peak -1 dBFS is safe everywhere. For voice and podcasts, loudness around -16 dB RMS is comfortable; streaming platforms target roughly -14 LUFS.

Will it clip or distort my audio?

No. In loudness mode a soft limiter catches any peaks that would exceed 0 dBFS, and peak mode by definition never exceeds your target.

Is my file uploaded?

No — measurement, gain and export all happen locally in your browser.
