Normalize (LUFS)

EBU R128 loudness normalization. Pick a target loudness and get a balanced MP3 output.

Target loudness

One-pass loudnorm
Fast single-pass EBU R128. For absolute precision you can later add two-pass mode.
Clipping safety
True-peak set around −1.5 dB in the filter to avoid inter-sample clipping.
Use cases
−14 LUFS for streaming music, −16 LUFS for podcasts, −18 LUFS for spoken-word content.

About

This tool helps you normalize audio loudness so files sound more consistent when played back-to-back. It’s especially useful for podcasts, interviews, voice notes and clips recorded on different devices where volume varies a lot.

Normalization adjusts the overall gain to reach a target loudness. It doesn’t remove noise or improve recording quality, but it makes playback less jarring and reduces the need to constantly change volume.

For best results, trim unwanted parts first and remove silence if needed. Then normalize the final output. If clipping occurs, lower the target or leave more headroom.

FAQ

What is LUFS?
LUFS is a loudness unit used to measure perceived loudness. It’s common in broadcast and streaming workflows.
Does normalization remove noise?
No. It changes gain. If your audio is noisy, noise may become more noticeable after normalization.
Will normalization cause clipping?
It can if the audio has peaks near 0 dBFS. Use a lower target or limiter in advanced workflows.
Why does my voice still sound different?
Normalization equalizes loudness, not tone. Different microphones and rooms still sound different.
When should I normalize?
After trimming/merging, normalize the final file so the whole track has consistent loudness.
