Hi,

Is it possible to grab some files from an audio CD and put them on a
different audio CD _without_ using digital audio extraction first?

e.g. is there a way to extract the raw PCM data to a hard drive, then
burn that data to another CD?

As I understand it, extracting using DAE would alter the original data
because it uses sampling?

In Windows the "raw" track data would show up as something like
TRACK001.CDA, I'd like to be able to copy this file direct to a
different CD possibly with a different track number, such as TRACK003.CDA

CDA files contain no actual A/V information. If you check, you'll find that CDA
files are small as opposed to multi-MB WAV files that contain music tracks.
Audio tracks must first be "ripped" from a CD before they can be recorded to
another CD. I'm not aware of any programs that do all this automatically,
although there may be. I use Exact Audio Copy for the ripping process. It can
even handle CD burning, although you may prefer something a bit more versatile.

EAC is free. You can get it here:

| Yes, usually using DAE to a WAV file?

Perhaps I'm not understanding precisely what you're looking for. I'm aware of
two ways to get audio information from a CD: DAE (digital audio extraction) and
AAE (analog audio extraction), the latter involving use of a soundcard or some
other form of digital-to-analog converter (of course, even AAE employs DAE as a
first step). Perhaps there is some very expensive equipment available at the
professional level that can duplicate the detailed landscape of a CD, but I
can't imagine what the benefit could be over DAE.

Once it has been properly set up, Exact Audio Copy can extract digital
information from a CD as well as any non-professional program I'm aware of.
Since audio data is never converted from the digital format in the process of
extraction, copying to a WAV file, and then ultimately burning to a CD, the
procedure should result in a copy that is indistinguishable from the original.

Having said that, however, I should add that "indistinguishable" depends on the
quality of the original where a properly set up EAC is involved. Because of
EAC's tenacity in reading damaged CDs, it is often able to extract digital
information that many CD players will miss. The CD copy could actually be
audibly better than the original if the original isn't in pristine condition.

Thanks Robert,

Everything you say makes sense to me; I think I'll just have to use DAE
for the type of restructuring I want to do. Buying a specialist drive
would be a bit extreme!

As you point out, the DAE might even be better than the raw because it
will be error corrected.

I've got a big stack of compilation CDs and I want to consolidate them
into a smaller set without losing any Audio quality.

I also agree it makes sense to use a lower speed for this.
