Audio volume tool
Audio Volume Booster
Make quiet audio louder in your browser, then export the adjusted result as an MP3 file. This can help with voice memos, lecture recordings, rehearsal audio, and practice materials that were recorded at a low level.
When volume boosting helps
Use this tool when the whole recording is too quiet but still clear. A moderate boost can make speech easier to hear or help a practice track play at a more comfortable level on phones and small speakers.
Avoid distortion
Boosting volume too much can cause clipping, where loud parts become harsh or distorted. If the source file already contains clipping or heavy background noise, volume boosting cannot fully repair it. Start with a smaller boost, listen to the result, then increase only if needed.
Good workflow
- Select the quiet audio file.
- Increase the volume gradually.
- Export an MP3 copy and keep the original file unchanged.
