I'm always on the hunt for ideal archival formats for digital media.
The ideal archival format has a few properties, ranging from most theoretical to most practical:
- a completely unencumbered specification and a completely unencumbered implementation
- a highly portable, f/oss reference implementation
- excellent quality vs. usability (e.g. lossless quality, but small to store and fast to decode)
- support in popular general purpose computing environments
- supported in popular dedicated hardware devices
FLAC gets the first few of those, but not the last one -- plenty of dedicated hardware audio players don't deal with FLAC.
Because of this, I use MP3 for audio - which theoretically gives up the first few points, but as a practical matter, those points are irrelevant, and MP3 completely dominates the industry on the last few points.
If Vorbis or FLAC or any of the things that get the first few points correct had ubiqoutous device support, I might be willing to re-rip everything into those formats for a great blend of long-term archival and easy-to-consume on any device convenience. But nothing is like that for audio.
Similarly, if I thought there was going to be a fantastic lossless image format that did everything well and was going to be massively supported and was completely unencumbered, i'd want to move everything over to it. I'd want my future digital cameras to start shooting it. I'd want my whole tool stream and whole life to just be about that format.
