Why normalized audio can sound quieter
A loudness target may reduce a heavily limited source so its integrated level and true peaks fit the target.
Reviewed against current browser behavior and AudioFetcher test fixtures on July 28, 2026.
Check these first
- 1
Compare integrated loudness, not only peak height.
- 2
Check true-peak constraints.
- 3
Look for one unusually loud section affecting the analysis.
- 4
Compare with loudness normalization disabled.
Reliable fixes
- Use a target appropriate for the destination.
- Edit extreme sections before normalizing an entire program.
- Keep the original for A/B comparison.
Change one variable at a time and test with a short known-good file. That separates a damaged source from a browser, codec, or memory limitation.
