K3b Audio CD - [Q] regarding "index"
This is my first try at using K3b to burn an audio CD...in fact, my first try at buring an audio CD at all in Linux, though I've burned a few in Windows. I think my question isn't K3b specific, but more general audio CD burning.
I'm assembling tracks from vinyl, not ripping CDs, so have individually recorded, split and cleaned tracks in WAV format, with about 1-1/2 LP per CD.
In the K3b GUI, in the Properties window for a given file to be burned, the bottom section is "Indices".
(1) What are indices?
(2) There is what appears to be a time scale bar with a readout as I hover the cursor over it along its length. There's a check box followed by "Index" and an underlined number followed by a time readout with up and down arrows, followed by another time readout with arrows labeled "gap". This appears to be some way to set an indexing point within the track, but as a newbie at this, I'm not sure if I need to do anything with it or if it's just optional for setting address locations. Can anybody explain and tell me if I can get by without it, or if it's important, and if so, how to use it.
(3) What is the checkbox named "preemphasis" in the options section for?
(4) Once I have all of the files entered and the metadata, am I ready to burn? Any other suggestions?
(5) I have a part of a cone of blank Memorex CDs that were bought by somebody else - probably in ignorance - several years ago. They are labeled "music" CD-Rs. We intended and started using them for storing digital photos, but had various problems that I was told was due to their being intended for music - something about copy protection. Any truth to that, and if so, is there any advantage or disadvantage to using them for audio CDs, at least for practice, other than probably not as long-term stable as curren technology?
Thanks for your assistance!
