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

Audio AC3, AIFF, MP3, WAV, WMA
