Normalize voice notes, podcasts, recordings, and extracted video audio locally.
Loudness is best for speech; Peak is a quick level cleanup.
Audio normalization evens out loudness so speech and music are easier to listen to. Use loudness mode for voice content and peak mode for quick volume cleanup.
Normalization is useful when recordings are too quiet, when different clips have inconsistent volume, or when a voice track needs to sit at a more comfortable listening level.
Loudness normalization targets perceived volume, which is usually better for podcasts, interviews, tutorials, and voice notes. Peak-style normalization is simpler and focuses on avoiding overly low or overly hot signal levels.
The tool can also read audio from many video files, making it useful when you only need a normalized audio track from a recorded meeting, lecture, or phone clip.
Loudness mode targets perceived volume and is usually the better starting point for speech, podcasts, interviews, and mixed recordings. Peak mode uses simpler level control when you mainly need to restrain strong signal peaks.
No. Normalization adjusts level, while the Audio Volume Changer applies one fixed gain to the entire track. Neither operation removes background noise or restores detail that was already lost to clipping.
Yes. Select a supported video and the tool processes its audio track, then exports an audio-only file. The video picture is not included in the result.
Normalization always creates newly encoded audio. Original format keeps a compatible source audio format when available; video and unsupported source formats use a compatible audio output instead. Lossy formats can introduce encoding changes, so compare the processed preview before downloading.
