XP's built-in burning software will automatically close a disc after writing
an audio file/s. This is done in order to make such files compatible with
standalone players. Burning an audio file on a disc used for other data
should not compromise retrieval of that data.

A kludge worthy of a test. Alternatively, install a more sophisticated
burning utility.

Thanks for the info. My agency sends out CD's with data on them. We would
like to close the CD so that info cannot be added or deleted from what we
send out due to legalities. Info on CD we send out could be used in court.
They are not audio, just data. The link really didn't tell me how to close a
data cd. Is there a way ?
Thanks,
Debra
 
Okay...I just burned an audio CD and it did close the CD. But it converted my
..wav files to .cda.
Can I stop this and keep as wave ?

Why not burn with a program like NERO or Roxio - They give options to
finalise the disc after the burn...

Just a thought...
 
Good question. We had our two users who do this for our agency use Roxio in
the past. And we had nothing but problems, all user errors. I even went so
far as doing a step by step instruction and still users could not get it
right. Using Windows XP has made it easier for them, acually, they have been
doing it well without errors but now we have the issue of CD going out
"opened " . We need it closed. Mind you, these two users are supervisors and
just aren't computer literate !!!

Keep in mind that a *.wav file is really a data file and
it is not playable in an audio CD-player. Essentially, one
chooses the option for creating a data cdrom instead of an
music one.
 
Thanks Ghostrider.
But since I'm completely confused now let me give you all some more history
and maybe I can get some more info.
I work for a law enforcement agency. Almost daily the public or DA office
requests certain data which are 911 calls. This is the info my two users are
burning to CD. The file format of these files are .wav. They have been
burning them as data files but since I have found out the CD isn't closed, we
are concerned. So can someone recommend the best way to burn these files ? As
far as I know, these CDs are played in either a computer or CD player. Which
would be the best way to burn these to be read on both if possible ?
Thank you ,
Debra

WAV files are audio data files that normally can be played only from a
computer's CD drive. When opened, they launch a player - such as Windows
Media Player. That is not to say that there may be a standalone CD player
(not on a computer) that can read them, but that's not generally the case.

CDA files are converted WAV files that will also launch a media player on a
PC. They work with a standalone CD audio player as well. Thus, they might
be suitable for your needs. As you have noted, once XP burns an audio
file/s, creating CDA files, the disc containing them is automatically
closed, and no files can be added thereafter.

If you need a burning application that can close a DATA disc - retaining the
WAV files as they are - a third-party burning utility may be the best
recourse, unless someone here suggests a method for closing a data disc via
XP's built-in software. I haven't run across one.

From a documentation standpoint (and I am in healthcare),
it would be best to convert the *.wav file to an audio
(*.cda) file. The most important reason for doing this is
to put the 911 call into the best format for playback in
the most venues. The next important reason for doing the
conversion is the ability of your agency to certify that
it has the original *.wav file of the 911 call and that
the conversion to *.cda was done under its control. And
third, it takes more steps to alter the *.cda audio file
since it has to be "ripped" and then digitally edited. In
fact, are there no written standards or guidelines for the
handling of such material under these circumstances as part
of the custodial chain for evidence?
 
Thank you both so much. I will take the info you both have given me to my
supervisor and will let him make the decison. But after reading what you all
had to say, I think .cda is the best bet. And Ghostrider, you seem to be in a
similar situation concerning medical records.
Thanks again,
Deb
