[TriLUG] Sound recording/editing/archiving - where to start?

[al johson]

Yep, I think we are in agreement, save one point. I do often use UDF on
CD-R's simply because at 15 cents a copy you don't mind if you have to throw
it away. It's especially useful when you're in a rush. You just format the
CD-R (or RW) and save the files you want to make portable on it. However,
you must make sure that the computer you're going to use it on can read
them!! So if anyone knows whether there is software available to read UDF
disks in Linux, I'd love to hear about it.
    On the distinction between 700 and 640 disks, I'm probably dating myself
but the size difference used to be the only thing that differentiated Audio
from Non-Audio blank CD's. Then someone had the good sense to realize that
they could save money if they just made the 700 size. ---Hope you're doing
well.---Al
