[Flashcoders] is there a dsp lib with analysis using zero crossing in as3
Hello list, I have been doing some experiments, but although my stuff is working, it isn't optimized at all, and I would to try a reliable lib that uses zero crossings for analysis, if one exists. Any suggestions? I am really just interested in pitch analysis with very small sample chunks. Timber is not really necessary, so I, with my limited DSP knowledge, think the FFT is overkill; however, I absolutely admit I could be wrong and not seeing something important. Another thing is that I was thinking a good/cheap way to get rid of some low level background noise would be to normalize all values within the time domain with a very high gain factor, and just give max and min values for the zero crossings( e.g +3, -3 respectively... I know the numbers would obviously not be these ones). I know know frequency analysis would have to be preformed in order to remove a voice, but I am thinking that this could allow me to zero out/ignore, really low level/really high level background noise. Should I try something different? Again, I have just started reading through a copy of 'DSP: a computer science perspective', that someone gave me, and it seems like what I am talking about would work; yet, if not, and you have experience with signals analysis, I would appreciate the heads up. Thank you, Anthony ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] How do I create a CDATA node using AS2?
Anyone know how to create a CDATA node when writing XML in AS2?I tried Google. I looked in the books I've got.I tried extending XMLNode.I've had no success. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

In the xml node itself, the nodes content wrapped CDATA in the XML or the result of that node wrapped in CDATA in flash? xmlnode id=![CDATA[nodename]] xmlnode or xmlnode id=nodename ![CDATA[noderesult]] xmlnode or var result = ![CDATA[+this.xmlNode.firstchild.childNodes [i].childNodes[0].firstChild.nodeValue+]]; HTH, Karl On May 11, 2011, at 9:08 PM, jimlaf...@yahoo.com wrote: I am using an xml object and need to have a cdata node written out when I use toString() on the XML object On May 11, 2011, at 7:50 PM, Karl DeSaulniers k...@designdrumm.com wrote: ![CDATA[hello]] On May 11, 2011, at 6:45 PM, Jim Lafser wrote: Anyone know how to create a CDATA node when writing XML in AS2?I tried Google.

Ooops, sorry.
