How to Adjust Audio Volume
- Upload your audio file (MP3, WAV, OGG, FLAC, AAC, M4A up to 500MB) by dragging and dropping or clicking the upload area
- Review the automatic audio analysis showing current peak (max) volume and RMS (average) volume levels in decibels
- Choose your adjustment mode: Maximize Volume boosts to max without clipping, Balance Volume normalizes perceived loudness, or Custom lets you set an exact dB change
- Click 'Adjust Volume', then use the built-in player to compare original vs. adjusted audio side by side before downloading in MP3 or WAV format
Tips
- • Maximize Volume: Best for quiet files that need to be louder
- • Balance Volume: Great for making multiple files sound equally loud
- • Custom Adjustment: Use when you know exactly how much to change
- • Enable 'Prevent Distortion' to avoid crackling when boosting volume

Maximize Volume (peak normalization) boosts your audio to the maximum level without causing distortion, ideal for quiet recordings. Balance Volume (RMS normalization) adjusts the overall loudness to a consistent level, perfect for making multiple audio files sound equally loud when played together.
When using Maximize Volume or Balance Volume modes, the tool automatically prevents distortion. For Custom Adjustment, enable the 'Prevent Distortion' option to avoid audio crackling when boosting volume significantly. This limiter ensures your audio stays clean even with large volume increases.
