Common Use Cases
-
Distributing collections of AU system sounds or legacy audio clips as one convenient archive.
-
Backing up multiple AU audio files by compressing them into a single ZIP package.
-
Exchanging AU audio assets across different platforms using a universal ZIP format.
-
Archiving legacy AU files for preservation or transfer between systems.
Tips & Best Practices
-
Keep original AU files intact, as archiving does not alter their audio encoding or metadata.
-
Use ZIP64 extension for very large archives to ensure full compatibility and support.
-
Be aware that minimal metadata in AU files means descriptive information might need to be added separately if required.
-
Verify the ZIP archive contents after conversion, especially when using legacy AU files with varying encoding formats.
Limitations
-
Archiving AU files into ZIP does not improve AU format limitations such as minimal metadata or encoding compatibility issues.
-
Legacy encryption in ZIP is weak and not recommended for secure archiving.
-
Per-file compression in ZIP may result in lower overall compression than solid archive formats.
-
Large archives require ZIP64 support, which might not be fully compatible with all tools.
-
ZIP archive contents cannot be listed until the full archive is created unless special streaming modes are used.
