| Heritage | Windows/RIFF | Apple/IFF |
| Audio | Usually PCM | Usually PCM |

How to choose
- There is no automatic quality advantage when sample format and rate are identical.
- Test metadata compatibility before committing a large library.
The right choice follows the source and destination. Converting a lossy source to a larger file does not recover removed information, while keeping a lossless master leaves future delivery options open.
