| Paul,
I am very happy that you have offered to convert the Csound email into a
browsable html archive. The Csound community really needs this type of
resource. (In fact, I thought there was such an archive at one time?)
Currently, I am re-doing the Csound Front Page to replace the "out-of-date"
and miss-informed pages at both Leeds and Dartmouth. Both will be
acknowledged and sited for thier contributions. But hopefully, both will
be retired shortly thereafter. They were both excellent, in their time, but
have not kept up with all the changes in the language. (Martin Dupras has
offered to pull his page the minute we say so and the Leeds people were
asked formally at ICMC to do the same given the fact that their document is
discouraging more potential csounders rather than assisting them.)
The "New Csound Page/Faq" will be hosted by the MIT Press. It will be up
within the next two weeks and it will be a living document which I will
continue to maintain, revise and update.
Paul, The MIT Press may in fact be interested in hosting your html version
of the archive as well. I will work on that. For now, I would propose
that the archive reside at John ffitch's site and be mirrored at Piche's
site.
So happy you have offered to do this work. Looking forward to this
wonderful resource in the near future.
Yours Sincerely,
Richard Boulanger

Regarding archiving software:
I have just set up a mailing list using Majordomo on
my home machine here, and using MHonArc to archive it
to a directory of that machine as HTML. MHonArc is a beauty!
http://www.oac.uci.edu/indiv/ehood/mhonarc.html
My machine is a 486-100 running RedHat 5.1 Linux.
The archive is password protected, so I can't show you
mine, but take a look at the MhonArc site for some examples.
MhonArc can work in two ways at least. One is you feed it a
Unix mailbox of emails, and give it a target directory, and
bingo you have a beatiful HTML web archive.
Secondly you can run it just like you run MajorDomo within a
MajorDomo wrapper from the sendmail /etc/aliases file. This
feeds the email to it and it updates its database and adds
it to the archive.
Here is a generalised example of using MajorDomo and Mhonarc.
Run new aliases after changeing the /etc/aliases file!
xxxx: "|/usr/lib/majordomo/wrapper resend -l xxxx xxxx-outgoing"
xxxx-outgoing: :include:/var/lib/majordomo/lists/xxxx, xxxx-mhonarc
xxxx-request: root
owner-xxxx: root
xxxx-owner: root
xxxx-mhonarc: "|/usr/lib/majordomo/wrapper mhonarc -add -quiet -outdir /home/httpd/html/yyyyyyy
-rcfile mhonarc-my-resources "
The default is to display emails as courier, which is
excellent.
MIME attachments are decoded and made available as
clickable links!
With carful filtering (procmail?) the archiving could
be done in this way on a machine which is not the mail
server of the list.
If it was desired to put the archive on a separate machine
from where MHonArc runs, then it would be necessary to use
some kind of FTP program on the local machine, regularly or
each time MHonArc runs, to see which files have changed and
to FTP them to a remote machine.
See the following links for using Glimpse search engine and
the Wilma interface to it - I haven't done this, and Damien
Miller says that Glimpse may not be the best approach.

Yes, but they have two years' worth of messages up there! (At least I
think they do; I haven't been able to get past the main index.) So
either somebody quietly started a csound egroup way back then, or went
to the trouble to grab jpff's unix-mailbox text archives and added them
to the egroups archive.
I'm finding it rather odd (not to mention increasingly suspicious) that
no one has come forward to claim responsibility for this. I'm waiting to
see if the egroups staff has anything to say...
While I'm on the topic, is there anyone on this mailing list who
_actively_uses_ egroups to read/search this mailing list?

Hi all,
I recently saw the promotional prospectus of a low-cost PC sound card
(called MaxiSound or so) and I was *really* disapointed with its specs.
compared to Csound. Specifically, it is said to use a 3rd order
polynomial scheme for wavetable interpolation, when Csound only accepts
linear (1st order) interpolation.
As you may agree this cannot be accepted ;-), I=B4d suggest at least 3 ne=
w
opcodes, called maybe
oscilp
tablep
deltapp
with an additional parameter to choose the polynomial degree used for
interpolated readout.
I=B4m not very sure about the improvement in the s/n ratio and in the
frequency response in relation to the degree of the Lagrange
interpolator. Maybe some of you have any clues. But it would be nice to
implement such feature.
Another question related to waveguide opcodes. Does deltapi (and delayw
btw) accept fractional sample delay lengths (well, fractional 1/kr
units) ? If not, is it expected to implement it soon? Otherwise it could
be difficult to tune a delay line at a precise high frequency, esp. at
low k-rates.
This is specially noticeable when developing waveguide models.

I think that having higher order interpolation opcodes may not really
be necessary in csound. Here are several reasons:
1.) You can do it if you need it in an orc using phasor and table. Just
take the two adjacent values and interpolate any way you want between them.
2.) It doesn't make much difference if you use large tables. Most of us
have lots of RAM and can make our tables as large as we like. The
interpolation error for a 200 Hz. sine wave using a 16k table is very
very small, and unlikely to be improved by a higher order interpolation.
The sound card probably has memory restrictions, so they use small,
down-sampled tables and try to make up for it with a higher order
interpolation. So what you are really seeing in their spec is their
low-cost solution, not a leg up on csound.

Actually, the 3.485 I tried in OS8. It hungs. However, v. 3.484 hangs
if I give it a large buffer. For what I was doing, I didn't care much
about the latency, but I had some complex orcs and I wanted to get a
clean sound. It hungs the perf (I had to "force quit") if I go over
... hmm, here I forget the fugure... 1028, maybe.

The problem is: does it improve the sound quality? How much does it cost =
in processing
speed?
My new SoundBlaster Live has an internal wavetable synthesizer who does 8=
point
interpolation in realtime. Actually the sound quality is excellent. I don=
't know if it
depends of the interpolation algorithm or of the hardware analog converte=
r.
Where is it possble to get the algorithm to implement 8 point interpolati=
on? If I could
see an example of it I will implement it in Csound.

Yes it does.

The problem is that the first order filters that are implemented in the w=
aveguide opcodes
don't use fractional delay, so the pitch of high notes is not precise.
