Thanks Joerg. <br><br>although to be honest, I wasn&#39;t looking for the theoretical solution<br>but what kind of Chuck code objects to use for this. My Chuck<br>learning curve seems way slower than Python/PD, I don&#39;t know why.
<br>I think it&#39;s the lack of explanatory notes in examples, or some kind<br>of proper tutorial.<br><br><br><br><div><span class="gmail_quote">On 10/16/07, <b class="gmail_sendername">joerg piringer</b> &lt;<a href="mailto:joerg@piringer.net">

that could be a rough estimate of the frequency. this is not very<br>reliable but works quite well with sounds that are not too hissy. low<br>pass filtering before counting helps a little bit.<br><br>best<br>joerg<br><br>
