Re: [Flashcoders] is there a dsp lib with analysis using zero crossing in as3

Oh, I also wanted to mention that over the weekend(thanks to wikipedia) I tried a simple AMDF style approach; it seems it would be great for very basic live tuning apps, but it does appear Gerry is correct that it may lead to issues if used for anything else. I also know, from what I have read

Re: [Flashcoders] is there a dsp lib with analysis using zero crossing in as3

Just wanted to say thanks for the responses; especially from Gerry. @Gerry: I think your comments about correlation have pushed me in the right direction. On 5/12/2011 8:49 PM, Gerry Beauregard wrote: Hi Anthony, For pitch analysis, what technique to use depends a lot on the specific appli

Re: [Flashcoders] is there a dsp lib with analysis using zero crossing in as3

Hi Anthony, For pitch analysis, what technique to use depends a lot on the specific application and the expected signal. Some considerations... Is the input monophonic (e.g. one singing voice or single pitched instrument) or polyphonic (piano, orchestra, etc.)? Does the pitch analysis need

Re: [Flashcoders] is there a dsp lib with analysis using zero crossing in as3

there's probably something like that in Andre Michelle's tonfall library http://code.google.com/p/tonfall/ there are some classes in there that make it easier to process audio signals, but I don't know if there is something doing exactly what you want. If you only want something to evaluate when

Hi, Andre Michelle did some nice talks about simple audio stuff - his sources may have some useful "helpers" http://blog.andre-michelle.com/2008/fotb08-sildes-and-sources/ Also checkout his lab page: http://lab.andre-michelle.com/ There is an EQ filter on there, which might be u

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.
