I'm sure you received many responses, but if not I would likely choose 
audio CD, but I would make the recording with some of the newer equipment 
that can sample at 24 bit, with 96kHz sample rate.  This will offer much 
better fidelity for the future.

Best of luck, if you have any questions feel free to contact me.

M. Fouche,
Your question about recording a large archive was forwarded to a jazz list
where I read it.
I am no expert on recording, but am a computer professional a jazz musician
and an
avid listener to records.

You should really create something on CD which ULTIMATELY(!) can be turned
into the
Digital Audio format so that it can be played on normal CD players. However,
you can
stage this process by recording a single file to a CD, if you make sure that
your music
source retains appropriate and consistent gaps of silence between "tracks".
Then
you can use a program such as "Digital CD Recording Studio" by Macmillan
software
(http://www.macmillansoftware.com)
or Easy CD Creator (Pro version) to read the resulting large wav file (if
you have
memory large enough -- to divide it at the gaps and turn it into a set of
files (track)
which can then be written to audio CD.  -- Remember the latter can be used
on both
computers and normal CD players, so it is the ultimate desirable format.
Thus by
choosing to write one large wav file (if done right) you have NOT precluded
the
ultimately desirable form -- to be done by yourselves, or later by some
other interested
party.

Regards and " bon chance," - or something like that.

If playback compatability is of concern I would choose CD-DA.  Users can
play it not only in standard CD players but most computers as well.  As
far as the extra time to PQ code a disc, an experienced engineer with good
tools can do that in a matter of minutes.

     Dear Jean-Pierre,
         Yes, we prefer "Orange Book" CD-Rs (which gets converted to "Red
     Book" once the table of contents is finalised). The way we do it is
     not to use a computer at all (except for printing the inlay cards and
     cataloguing the results). We use audio CD-R machines. This may imply a
     rehearsal to get necessities of life (like durations and "out cues",
     so we know when tracks end). Alternatively, we use the CD-RW format
     (Compact Disc Rewritable), which allows you to erase the previous
     track if something goes wrong without losing the whole thing. We
     thereupon "clone" the result, making (usually) two copies on two
     different makes of CD-R blanks to avoid "putting all our eggs in one
     basket", as we say in England! Many of our contractors use digital
     editors or Exabyte systems or other ways of "massaging the data"
     before burning the CD-R; but that's what we do here. You can always
     add another "track flag" by pushing a button as the tape plays (or
     whatever) without stopping; but it can only be done at x1 speed.
         Hope this answers your question,
     Peter

Dear Peter,

The only other time I remeber reading the word 'insidious' was, as I recall,
from Shakespeare - 'an argument of insidious intent' - so I've referred to
our wiser cataloguer here to get the meaning.

Am I right in understanding from you that CD-Digital Audio is the preferred
medium for archiving?

If so, does that mean that each digital sound file recorded onto a computer
has to be chopped up into one-track units of sound files, in order to make a
cd?  That does indeed seem to be a long and tedious process.  [C.f. the .wav
method, which allows us to copy a large sound file as a single block (in
which there may be many tracks), thus eliminating the extra time needed to
chop up the original file, recorded in toto from the analogue.]

Best wishes

It has been my experience when determining the best access for archival
materials is to first determine who will be using the information and what
is the easiest form of access that can be provided to them. What
equipement are you providing your patrons to access the new medium?  Will
you circulate the new product? You're user population should be the
driving force in this.

As a musician, I would much prefer to have a CD with individual tracks.  I
would not want to stare at a blank computer while I listened to the
particular track that I wanted (however, if I had access to word
processing, etc. I could take notes while I listened. The same could
also be said about pencil, paper (regular and staff) and portable CD
player).

I also feel that CD-ROMs are at risk of being fazed out with the
availability of DVDs.  Note that I'm saying at risk of and not
going to, however, U.S. government CD-ROMs are already undergoing this
transition since more information can be stored on DVDs.  My experience
with DVDs also tells me they are easier to use than CD-ROMs.  If all
CD-ROM producers follow suit, how long will it be before our new computers
did not read CD-ROMs but only DVDs (just like 5 1/4 and 3 1/2 floppys).
CD-ROMs will probably  be around for decades still yet but these are the
things that would be going through my mind in making a decision.

Dear Mr Fouche
Your questions are ahead of me. I have yet to get to transfer-formats for
the collection I am working on, although I will begin to address that issue
in a few weeks. I had wondered about exactly the question you posed though.
I thank you for your passing on what you know.
>From the outside, it seems to me that while it may take longer, CD-DA is
the option to pursue because it allows for the widest possible access to
the content. A good collection is an accessible collection. However, I do
not know what the audience for your collection is, and/or how access fits
into your mandate.
Thank you for your input. I know I have learned from you. While my feedback
is more theoretical than constructive I hope it is of some use.

William Meredith
