[linux-audio-user] cd burning w/out gaps

[R Parker]

Hi,

I see a few other folks replied with good answers.
Like some of them, I use cdrdao and a script. You
probably have a solution so this won't be particularly
interesting. Reguardless, I'll post my script. It
might be helpful to someone.

The script assumes a directory structure '~/clients/'.
When run, it searches clients and asks which one to
burn a CD for. After making your choice, it searches 
'~/clients/clientname/master' for *.wav. You are then
prompted to specify the amount of time between each
track. The format is 00:00:00. A minimum of 00:00:01
seems to be required.

The script generates the file cd.toc based on the
contents of ~/clientname/master. The script will ask
you if you want to use an existing TOC or generate a
new one.

This script isn't an example of good code. I needed a
solution and cobled it together.

Incidentally, I also use a script to add clients into
'~/clients/'. I require about eight subdirectories for
each. That's why the script is designed with a hard
coded directory stucture. In my studio data management
is not left to the engineers discretion. Everyone of
us manages their data exactly the same way.

If you add the following function to your .bashrc,
then at a command prompt 'client-mastercd'.

client-masterCD ()
{
~/.bin/mastercd
}

I've got a dozen or so tasks that each engineer must
run so having a series of functions named
client-whatever in .bashrc helps.
