Normalize Audio to a Consistent Loudness
Choose a target level and protect peaks for more even playback.

Finish the normalize audio result in VisionStory
Audio normalization applies gain so a file approaches a chosen level, making playback more consistent across episodes, clips, or delivery contexts.
Keep the source ready for reselection
Actual normalize audio processing, result inspection, and download happen in VisionStory. The next step may require the source file to be selected again.
Approve the measured output, not an estimate
Check the properties that define a successful normalize audio result and retain the original until the destination accepts it.
Test the real receiving workflow
Confirm LUFS, peaks, dynamics, and clipping in the intended destination before approval.
Check your result
Check loudness, peaks, and quiet passages
Compare loudness and peak measurements before and after processing. Listen to quiet passages and loud transients for clipping or other unwanted changes.Check average level
Compare the measured program loudness with the target required for your specific destination.
Check peaks
Inspect peak levels and listen to loud transients. A suitable average level does not guarantee freedom from clipping.
Check quiet passages
Listen to pauses and soft sections for distracting background noise that becomes more noticeable when gain increases.
Technical anatomy
Normalization Does Not Automatically Repair Dynamics
Applying one gain change can move the whole program toward a target without reducing the difference between quiet and loud passages.
Distinguish gain from compression
One gain adjustment raises or lowers loud and quiet passages together. It does not automatically reduce the range between them.
Listen to transients
If limiting is applied, sharp peaks can change shape. Listen to drums, plosives, and other short loud sounds after processing.
Review background noise
Raising gain also raises existing noise. Check pauses and quiet passages instead of judging only the loudest section.
Level targets
Balance Loudness Without Clipping
Use practical targets for publishing contexts.
Streaming target
Prepare a common music-platform loudness level.
