# Normalize audio loudness — even out volume, no upload

> Normalize audio to a target loudness (LUFS) for podcast, streaming, or broadcast, with waveform preview. Exports MP3, M4A, or WAV in your browser — no upload.

Standardize a recording's volume to a target loudness (LUFS) for podcast, streaming, or broadcast, with a waveform preview. Encoding runs in your browser, so the audio isn't uploaded.

Uneven loudness is what makes a podcast feel amateur — one guest booming, the next barely audible. Normalizing to a loudness target evens the whole file to the level streaming and podcast platforms expect, so listeners aren't riding the volume knob.

The waveform preview shows the effect before you commit, and local encoding keeps unreleased episodes off any server. To cut sections first use Trim audio, and to change the format use the Audio converter.

## How to

1. **Add audio.** Drop an MP3, M4A, WAV, or other audio file.
2. **Pick a target.** Choose a LUFS preset for podcast, streaming, or broadcast.
3. **Preview.** Check the waveform and level before export.
4. **Export.** Render MP3, M4A, or WAV locally.

## FAQ

### What is LUFS and why normalize to it?

LUFS measures perceived loudness. Platforms target specific LUFS levels, so normalizing to the right one keeps your audio from being turned up or down on playback.

### Which preset should I use?

Podcast and streaming targets sit around -16 to -14 LUFS; broadcast is louder. Match the platform you're publishing to and the preset handles the rest.

### Is my audio uploaded to normalize it?

No. Loudness analysis and encoding happen via FFmpeg in your browser, so the recording stays on your device.
