Free online audio volume booster

Raise the overall level of a quiet recording

The volume booster increases the level of an entire recording. Use it for a quiet voice memo, a low-level music file or a sound effect that needs a louder export. It changes overall loudness while keeping the original tempo and pitch.

Adjust output gain from -24 dB to +24 dB; the result regenerates automatically. Positive gain raises the level; negative gain reduces it. A soft limiter rounds peaks when they exceed its threshold, so a strong boost can also change the sound’s dynamics.

Gain makes quiet passages louder. The soft limiter rounds peaks above its threshold to avoid digital clipping. Strong boosts change dynamics and may sound compressed; they cannot repair an already distorted recording.

Privacy and sound quality

Your recording stays on your device. Effects run locally in WebAssembly. Effects regenerate automatically after settings change. The preview and download share the same processed audio. The soft limiter protects against digital clipping.

Time stretching can introduce artifacts, especially at extreme settings. Processing long recordings needs more memory; start with a short clip on mobile.

Frequently asked questions

How does the volume booster avoid digital clipping?

Output gain raises the signal, and a soft limiter rounds large sample peaks before export. Strong boosts can still change dynamics or sound compressed, so listen before saving your file.

Can increasing volume repair a distorted recording?

No. The booster changes the level of existing audio and cannot restore detail already lost to clipping. If distortion becomes more obvious, reduce the gain and work from a cleaner source recording.
