Reduce, boost, or mute a video's audio locally, or run measured two-pass loudnorm processing for streaming, voice, broadcast, and custom targets.
Measured two-pass LUFS normalization
The first pass measures loudness, range, and peaks; the second pass applies those values for more stable loudnorm output.
True Peak clipping protection
Choose a peak ceiling and apply a limiter to leave headroom for AAC encoding and platform conversion.
Original video preserved when possible
Compatible video streams are copied while audio is re-encoded, with H.264 used only as a fallback.
Video volume and loudness normalization FAQ
Is my video uploaded during volume processing?
No. Audio detection, loudness analysis, filtering, and MP4 export all happen locally in your current browser.
What is the difference between gain and loudness normalization?
Manual gain adds or removes a fixed number of decibels. Normalization first measures program loudness and calculates the adjustment from a LUFS target.
Why does loudness normalization use two passes?
The first pass reads the complete track to measure Integrated Loudness, LRA, True Peak, and threshold values. The second pass applies those measurements.
Should I choose -14, -16, or -23 LUFS?
-14 LUFS is a common streaming target, -16 LUFS suits podcasts and voice, and -23 LUFS is close to common broadcast targets. A custom target is also available.
Why is the video sometimes re-encoded?
The tool first tries to copy the original video stream. It falls back to H.264 only when the source codec cannot be packaged reliably in MP4.
