About Audio Volume Booster
Audio Volume Booster raises or lowers loudness so quiet recordings become easier to hear.
Upload the file, adjust volume, and download. Avoid extreme boosts that clip and distort peaks.
Use it for voice notes and lecture captures. For broadcast-ready loudness standards, a dedicated mastering workflow is still better.
Example workflow
Choose a volume multiplier from 0.5× to 4× and download WAV. A 0.5× setting makes audio quieter; a 2× setting increases amplitude by approximately 6 dB.
Output checks and limits
This operation runs in your browser. High gain can clip peaks and distort voices or music; listen to the result before replacing your source. It does not recover detail from a noisy recording.
