Actually, DC offset could be covered in "What is Digital Audio", since
it is a concept that needs explaining. Then, my suggestion still is to
include it after the basics of the Square Waves. I'd like to keep the
patches there as simple as possible, and since the DC Offset can be done
at the end, why not have it there?
Triangle wave would also be good. Write it first and we'll see where
exactly to put it.

sure, I could do both.
But I think it would be inportant to start just after
* AUDIO TUTORIALS
* SimpleSynthIntroduction
<http://en.flossmanuals.net/PureData/SimpleSynthIntroduction>
and before the oscilators with the Short DC offset chapter.
Then edit and correct the oscilator patches with values from -1 to 1
I also can create and put in the oscilator chapter a Triangle wave
oscilator made with phasor
what do you say?

Alexandre,
Yes please, get on board!
In the case of the square wave chapter, I had assumed that doing it
with digital logic would result in either 0 (no amplitude) or 1
(full amplitude). So there shouldn't be any DC offset when it's at
0. Of course, there are some other real-world problems with those
patches, namely that there is also no antialiasing.
Since the FLOSS Manuals are "modular", they can be remixed as needed
for any kind of workshop, class or curriculum, including or leaving
out sections from all the different FLOSS Manuals as needed.
So my suggestion to you would be to write a short chapter on DC
offset which can then be referred to in the square wave tutorial, or
in any other tutorial or manual where such a situation might arise.
Likewise, I'd love it if someone could do a single chapter on the
different antialiasing methods (Miller's, Frank's...). The idea
would be to simplify the explanations so that one doesn't need a
background in DSP or computer science in order to understand them.
Would you be interested to do either of those?

Hi, I am really interested in helping!
I actually have some stuff I wanted to "corrrect", or bring some
attention to, like the DC OFFSET. You dont cover it, and when
you show how to get a Square Wave, the DC Offset is not properly
adjusted.
thanks
cheers

Hey Alexandre,
I just posted the announcement of the Pd FLOSS Manuals Book
Sprint:
http://lists.puredata.info/pipermail/pd-list/2009-03/069107.html
I was wondering if you'd be interested to help out next
weekend? It
shouldn't be a problem to contribute remotely, and it would
really help
build up the momentum to finish this manual.
Have a look over the topics and see if there is anything
you'd like to
cover and let me know.
Best!
Derek
