Audio clipping: causes, detection, and prevention
Clipping occurs when a signal exceeds the available range and peaks are flattened, creating distortion.
Reviewed against current browser behavior and AudioFetcher test fixtures on July 28, 2026.
Key facts
Positive gain can push an already loud file into clipping.
Lossy encoding can create peaks above decoded sample expectations.
Reducing gain after clipping cannot reconstruct flattened peaks.
True-peak limiting is different from simple volume adjustment.
Practical decisions
- Use small boosts and listen to the result.
- Start from an unclipped source whenever possible.
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.
