Tutorials - Yes I have them.

SubjectTutorials - Yes I have them.
Yes, I have the tutorials, but only in Acrobat format right now. They are
in the Supplement. You can get it from:

http://www.geocities.com/~csoundmanual

The tutorials never (well, rarely) change. The manual changes constantly.
Some people do not use the tutorials, so it makes sense to put them in
another volume. They are out of the way if you don't need them, but
available if you do. And they don't get in the way of manual maintence, you
don't have to download them unless you want to, etc., etc. 

In maintaining the Acrobat manual, I have tried to arrange it so that one
needs print as few pages as possible with each update, and simply add or
replace them into an existing copy. After all. I and many others like to
have an up-to-date hard copy of the manual, but don't own a paper mill, or
don't want to deforest the earth, or whatever.

Recently, the manual has become so unwieldy that its organization has
suffered and updates are large - sometimes as much as 1/3 the entire
manual. With the manual now at 400++ pages, that's a lot pf reprinting
every few weeks. I don't like this personally, I'm sure others don't
either. That is why it is undergoing major overhaul - to make maintenance
easier on my end, and updating your copy more efficient on your end.

It just makes more sense to have tutorials in a separate volume. If you
want them, please get the supplement. BTW, Dr. Boulanger has updated his
tutorial since the Bath manual.

Thanks to all for your support.

-David.

SubjectApologies, Re: Tutorials - Yes I have them.
I've been doing nothing but complaining lately. David, my apologies.
I'm glad to see the omission of the tutorials was intentional and an
oversight. Naturally, my first thought on finding this was to wonder what
else might then be missing. 

Thanks also for explaining the need for the reorganisation. I guess I
should have been paying more attention to the posts on this list.

If your version is indeed the currently maintained one, then I hope it
could be posted on the Bath site. I think this would make it more
"official".

...may I add that teh manual on what remains of teh Bath site was just what 
I was sent at some time.  I am not resposible fo rdocumentation --- basically
as a professional CS guy I just do not do that kind of thing.  If it
was difficult to write it shoudl be difficult to use(:-)

Javier, you sly dog you... Thanks a bunch for letting us in on this.

Like a good little upgrader, I'd moved from QT 2.5 to QT 3 to QT 4,
all the while getting rid of earlier versions of all components.

I dug up QT 2.5 off a CD-ROM, & reinstalled only MoviePlayer 2.5

It encodes !!!

So, using a test file, I tried 4 diiferent encoders :
- mPecker (I still use it by turning the clock back on my Mac, he he he... )
- Apple Quicktime 4 with MoviePlayer 2.5 (.mov format)
- Yamaha Sound VQ (.vqf format)
- RealProducer 6.1.0.153 (.rm format)

Here's the result & my observations :
format        file size      quality
___________________________________________________________________________
mp3            2.7 MB        best. marginally better than QT.
128kbps stereo

mov            1.2 MB        pretty darn good, but mp3 is a little better
40kbps  stereo               but consider the file size !

vqf            1.6 MB        close to QT .mov, but larger file, and much
40kbps  stereo               smaller user base.

rm             480 kb        encoded for 28.8 kbps streaming, acceptable for
                             the purpose. I could have tried encoding at a
                             higher rate, but since this is essentially
                             a streaming format, it's moot.

    I'm sending the orc & sco, but i don't think it's a good idea to
send the samples!!

    Anyhow, the clicks are "one sample out of range", only. But we can
hear them alright. And they are only on the right channel!

    I tried it with some other samples, some do clicks some don't .
Mystery!
I tried to play them with other softwares (like  Peak, soundapp, etc...)
with a positive result (no clicks!). Anyhow, i send the orc& scos, and
if someone wants to ttest with the samples i can compress them and send
them personally to him.
    thanks

Who is this saint, who, from time to time, offer us all the new versions of
the Csound manual, in any format _useful_ for consulting it, and quietly
accepting the suggestions of other users, without a complaint?

Thank you very much David, for your enormous effort keeping the manual tidy=

bad loop points.
rapid k-rate freq change.
no envelope on note-off.

Or, I have a set of AIFF files that have copyright
chunck at end.  As I remember, csound played the copyright
chunck very faithfully.  Sounded like a click though.

Read the following text carefully. Perhaps one of you can help me.

begin text
I think this command, fmmetal, needs some work. I get static and AM
radio
noises with it.
What did I do wrong?
I suspect it is with kc1 or kc2 or both. I did not know what to put
there.

It is a known bug with fmmetal that it is vulnerable to AM radio
frequency interference.  I sometimes pick up Limbaugh on one of
my orcs.  You can try padding the line holding the opcode with
white space, or if the interference is severe, you may have to
get a metal project box from radio shack, and enclose the fmmetal
opcode in that.  Be sure to use balanced, shielded cables to connect
the opcode to the rest of your orc.  Also be careful to insulate the
fmmetal from the project box or you may overload your dacs with
infinity values (they look like zeros, but are much more dangerous),
and run the risk of creating a short to the bit-bucket through your
body.  This is how Hendrix got started.

I'm glad you have a sense of humor, Toby. White space? OK, I'll try
that.
I've been learning these command for the past three years. It did not
make sense until I printed out the manual.
Now, I'm trying each one.
See you later

Assuming you're here in the US, you could try sampling one of the Radio
Pacifica stations (independent radio). Here in the New York area you
could try WBAI.  Sample an excerpt of any number of their programs (the
Pacifica news, for example), and then use the "balance" ugen in
conjunction with the Limbaugh orc. My experience is that the result is
often fairly close to the center, although my lowly P100 is sometimes
not up to the task of mixing the two.
 
Hope this helps.

Thanks Tobiah,



there's no loop points in the samples:
bad loop points.

I tried with a larger krate with the same result
rapid k-rate freq change.

I tried also an enveloppe for note-off
no envelope on note-off.

 I beleive it's the last reason invoked.

->Or, I have a set of AIFF files that have copyright
chunck at end.  As I remember, csound played the copyright
chunck very faithfully.  Sounded like a click though.

And it seems that the problem is in the middle of the sound
ANd my problematic sample was taken from a commercial CD. So how can we
view the copyright chunk and edit it, although it's not really legal,
it's just to confirm the problem which in this case is due to the sample
and not to loscil?

Thanks
karim
