Normalize Audio Online Free — Fix Volume Levels

Inconsistent audio volume is one of the most common problems in recordings. One person speaks louder than another in an interview. Background music drowns out narration. A podcast episode is too quiet compared to the previous one. Audio normalization fixes all of these issues by adjusting volume to a broadcast-standard level.

MiOffice normalizes audio to -16 LUFS (the broadcast standard) in your browser using FFmpeg WebAssembly. Works with both audio files and video files. No upload, no signup.

When to Normalize

• --Podcast episodes: Ensure every episode has consistent volume for your listeners.
• --Interview recordings: Balance volume between speakers who sit at different distances from the microphone.
• --Music playlists: Normalize tracks from different albums so they play at similar volume.
• --After audio extraction: Audio from video often has inconsistent volume. Normalize after using Video to MP3.
