Private Volume Control

Quiet recordings, mismatched podcast levels, or a track that clips your speakers — this tool fixes them locally using WebAssembly (FFmpeg) so your audio never leaves your device.

Two Ways to Fix Levels

Adjust Volume: Dial in an exact gain from -20 dB to +20 dB and hear roughly how much louder or quieter that will sound before you commit.
Normalize Loudness: One click applies the EBU R128 loudness standard, evening out a track to a consistent, broadcast-ready level automatically.

First Run Note

The first time you use this tool, it will download the audio engine (~25MB). This is a one-time download and will be cached for future use.
