Tests: Normalize
Main Page > Development > Development documentation > Tests: Normalize
Archivematica normalizes certain ingested file formats into preservation-friendly formats.
General
- Normalization is triggered automatically when the user approves "Appraise SIP" in the dashboard.
- The original files are not deleted.
- When normalized files have the same file extensions as the original, the original files are not overwritten.
- If the SIP contains files for which there are no default normalization paths, processing of the SIP does not stop.
Audio files
- .ac3 files are normalized to uncompressed WAVE
- .aif/.aiff files are normalized to uncompressed WAVE
- .mp3 files are normalized to uncompressed WAVE
- .wav files are normalized to uncompressed WAVE
- .wma files are normalized to uncompressed WAVE
