Volume Booster
Rescue quiet recordings: tracks load with a −14 LUFS integrated-loudness target already on, or push the gain slider up to +12dB yourself. Export uses a −1.5 dBTP true-peak ceiling to reduce clipping risk. MP3, WAV, FLAC, M4A, and OGG render locally.

How it works
Load quiet audio
Drop in a voice memo, recording, or song that's too quiet. Normalize is already engaged — press play to hear the difference.
Set the loudness
Keep the −14 LUFS reference target or drive the gain slider up to +12dB for manual control. Boost individual clips with per-clip gain.
Export any format
Render MP3, WAV, FLAC, M4A, or OGG on your device. Preview is approximate; the rendered export is authoritative.
Frequently asked questions
How loud can it make my audio?
The gain slider adds up to +12dB, and per-clip gain adds ±6dB where you need it. The normalizer instead measures integrated loudness and targets −14 LUFS, a common reference for spoken-word and online distribution rather than a universal platform standard.
Will boosting volume cause distortion?
Raw gain can clip once peaks hit full scale. The default normalization export uses a −1.5 dBTP true-peak ceiling to reduce that risk, but lossy encoding and downstream playback can still alter peaks.
Why is my exported audio still quieter than commercial tracks?
Commercial masters combine loudness normalization with compression. Add the "Music glue" compressor in the effects rack before normalizing — compression raises the average level, then normalize sets the final loudness.
Is my audio uploaded?
No. Gain, normalization, preview, and export all run in your browser via WebAssembly. Files never leave your device.
