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. The full guide How to increase audio volume explains headroom, normalize, and listening checks.
Step-by-step volume workflow
Load your file into Change Volume. Start with a small boost such as +3 dB or +6 dB, then preview. Check the loudest moments, not only the beginning. If the tool warns about headroom, lower the boost or enable peak normalize on export.
Optional fades can soften the start and end after a level change, which is useful when a boosted clip will sit next to quieter audio in a video timeline.
- 1. Load the file Import the quiet or loud recording into the volume tool workspace.
- 2. Set gain Move the slider in small steps and preview after each change.
- 3. Check peaks Listen to the loudest section and watch for harsh distortion.
- 4. Normalize if needed Use peak normalize when you want the highest peak near a consistent level.
- 5. Export Download a new file. Your original recording stays untouched.
When volume is the wrong first move
If the file is hard to follow because it is too long or includes dead air, trim first. If a meeting recording is quiet because one speaker sits far from the mic, gain can help, but noise under the voice will rise too. For call recordings, see Fix quiet Zoom recordings.

- Start with +3 to +6 dB and increase only if needed.
- Listen on headphones or decent speakers, not only laptop speakers.
- Check silence and pauses after boosting — noise becomes more obvious there.
- Keep a high-quality WAV export if you plan to edit again later.
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.
Does normalize remove background noise?
No. Normalize adjusts peak level. Noise reduction is a different process.
Can I fix clipping by lowering volume?
Lowering volume makes clipped audio quieter, but it cannot rebuild flattened peaks.
Should I boost before or after trimming?
Either order can work. Many people trim first so they only adjust level on the section they will keep.
