At first glance you would think so but that might not
be true. The TOC uses start and duration times to
describe where a song begins. I suspect there's
nothing to prevent song 01 start point from being
00:33:00:02 while song 10 start point is
00:00:00:02--pre-gap defined in frames works. I'll
test this later today and let you know.
A method of layout for the master .wav file is to
leave extra space between songs. Because Start and End
markers describe Start and duration, this enables us
to adjust timing between songs in the TOC without
burning a new .wav file. That's more a userland
strategy than a developer issue but it's another
example for avoiding Export.
I'll play with both these ideas later today.

Of course CD players don't but watch a client smile
when their titles scroll through the player display.
Reguardless, isn't it better to include all metadata
within the TOC as opposed to manually recreating it at
places like freecddb.org?
When I burn CDs at the studio, I generate a studio
J-Card with song titles, duration, contact
information, dates, and everything else that can help
my client keep track of their project. Alot of this
information can be extracted from the TOC. I've got
one album sittin here that we've been working on for
If I had my way about it, there would be calendars,
billing software and a fax applications in Ardour.
Maybe the guy writing songs in his bedroom can't
appreciate this rediculous joke. However, guys in my
position will scratch their heads, laugh and mutter,
"yea, no shit dude." Reguardless, Ardour is a DAW and
combined with JAMin it is a start to finish audio
workstation. Well, it will be when you marry libburn
into it. :) There might only be a few of us doing
Export from an Ardour JAMin return bus but in the
future there will be alot of people doing it.

Honestly, I think it's the right thing to do and I
didn't start thinking about this yesterday. I've been
mastering with Ardour and JAMin for a fair amount of
time and have seen numerous projects go from start to
finish. I'm just a luser in the Ardour world but if I
were a programmer the things we're talking about would
have been done six or eight months ago.
I do appreciate you putting up with me.
