Volume Booster
Upload an audio file and adjust its volume with a multiplier from 0.5x (half volume) to 3x (triple volume). The tool uses ffmpeg's volume filter to scale the audio amplitude uniformly across the entire file. Values below 1x reduce volume; values above 1x increase it.
This is useful for boosting quiet recordings, reducing the volume of clips that are too loud, matching volume levels between files, or preparing audio for environments where the original level is too low. Be aware that boosting beyond 2x may introduce clipping (distortion) if the source audio has loud peaks.
Everything runs in your browser using ffmpeg.wasm — your audio is never uploaded to a server.

Frequently asked questions
What's the difference between this and normalization?▼
Volume boosting applies a uniform multiplier to the entire file — everything gets louder or quieter by the same amount. Normalization analyzes the audio and adjusts levels to meet a target loudness standard, which may boost quiet sections more than loud ones. Use this tool for simple volume adjustments; use normalization for professional loudness correction.
Will boosting volume cause distortion?▼
Possibly. If the source audio has loud peaks and you boost by 2x or more, those peaks may exceed the maximum level and clip (distort). If you hear distortion, try a lower multiplier. For distortion-free loudness adjustment, use the Normalize Audio tool instead.
Can I reduce volume below 0.5x?▼
The slider goes down to 0.5x (half volume). For further reduction, run the tool twice — 0.5x applied twice gives 0.25x (quarter volume).
