Key facts
A +3 dB volume change is explicit.
Peak normalization uses the highest sample peak.
Loudness normalization estimates perceived level.
Neither process repairs existing clipping.
Practical decisions
- Use volume change for a known correction.
- Use normalization for consistency across recordings.
Measure the source before changing it. Codec, container, duration, channels, and intended playback environment are more useful than choosing a setting from its label alone.
