About this tool
Change Audio Volume Online — Free Gain Adjuster
Load your audio, adjust the gain slider to boost or lower volume, preview the result on the waveform, and export with optional fade in/out.
How much can I boost the volume?
The slider ranges from -24 dB to +24 dB. Loud boosts use soft limiting to reduce distortion.
Will boosting cause clipping?
The tool shows headroom warnings and applies soft limiting on preview and export to help prevent harsh clipping.
Can I normalize the output?
Yes. Enable peak normalize on export to bring the loudest point to a consistent level.
