Also, if this rumor is true, what would be a good
lossless codec to use? Lossy compression is out of the
question as we need to be able to reproduce all the data
20 years from now if needed in future formats. We dont
want to lose ANY of our bits and bytes by using lossy
compression.
The safest choice would be a zipped uncompressed WAV. And I
am not kidding: lossless music compression more or less
achieves around 50% compression, which is roughly the same
as zip. Of course, you will not be able to play the files
directly without unzipping them first. If direct playback is
important to you, go with FLAC: since it is open source, it
is unlikely to disappear on a whim and you can store the
source code somewhere for safekeeping and porting if need
be. If you want a widely supported lossless format, look for
Dolby lossless formats (MLP or TrueHD): since they are used
in HD DVD and BluRay, they are more likely to be supported
on devices than WMAL or FLAC (but finding encoders is going
to be still hard and you may have to pay a fee to use them,
you should check on dolby.com).
