#1 Burning Software

Hello, Anton!
Now I work on Audio CDs burning. Would you be so nice to give me some more enlightenment?
1. I use StarBurn_IsAudioFileSupported() for testing if user selected file is capable for writing as audio track. It looks like it works smart enough, but it is not documented. So is it OK to use it ?
2. I have to now length of future audio track before to burn it. Can I use undocumented StarBurn_GetAudioFileStreamSizeInUCHARs() for it? And what about between-track pauses, especially with DAO. You see, I need 100% method to say user is disc freespace enough to burn.

Thanks a lot!

Next one.
Is there any way to get artist/title tags from sound file if contained?
I mean using StarBurn.
Thanks.
