Audio tool
Change Audio Volume Online - Free Gain Adjuster
Use Change Volume to make a quiet recording easier to hear or reduce a clip that is too loud. Preview the gain before export and use normalize when you want a consistent peak level.
Use gain carefully
Raising volume cannot restore detail that was never captured, and very large boosts may make background noise more obvious. If the original file is already clipped, lowering gain will reduce level but will not repair distortion.
Audio Lab includes soft limiting during loud boosts to reduce harsh clipping, but it is still best to make the smallest gain change that solves the problem.
FAQ
Frequently asked questions
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.
