What about maybe bypassing some of the computation by including a human game in the process? E.g., make a spectral analysis of a participant's voice, then make a game of matching up visual patterns in that analysis with visual patterns in animal analyses. After selecting patterns that seem to match, the action could return to something computational, like vocoding. Maybe morphing from their spectrum to the animal's spectrum...<div><br></div><div>This may be irrelevant to your intentions! but Nuno's idea caught my imagination, and this is what came to mind.<br><div><br></div><div>bf</div><div><br></div><div><br><div><div>On May 23, 2008, at 4:47 PM, Peter Todd wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Hello,<br><br>There's an external for pd / max-msp called soundspotter designed for doing the kind of thing you want: <a href="http://www.soundspotter.org/">http://www.soundspotter.org/</a><br><br>I'm not intimately familiar with it's workings, but it is open-source and Michael Casey has written several papers on the subject which you'll find under 'Research' on that page.
