I've noticed that some systems actually don't create [>~] or [<~], so I was thinking to redo those sections with [expr~] anyways. If you'd like to jump in and do all that, it could work. The main part of that chapter is that it is also covering digital logic, so I wanted to stick with values of 0 and 1 for clarity. Do you see any way we can work this out?

well, for instance
inside the Squarewaves and Logic chapter
the DC Offset could be easilly built inside the EXPR object, either in the one that is already there, or in an object right after to make the visualization easier. I could edit all thos patches that need to adjust the DC offset.
On this case, it would also be nice to have the Tables just a bit larger that -1 - 1, (1.1 or 1.2) so we can better see the Square Waves.

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?

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? D.

You dont cover it, and when you show how to get a Square Wave, the DC Offset is not properly adjusted. thanks cheers On Mon, Mar 30, 2009 at 11:20 AM, Derek Holzer <derek@umatic.nl <mailto:derek@umatic.nl> <mailto:derek@umatic.nl <mailto:derek@umatic.nl>>> wrote: 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!
