<body class='hmmessage'><div dir='ltr'>Thanks for all your answers.<br><br><br><div>> This is fascinating. Would you mind if I prepare some short post to<br>> publish on aubio's blog?<br><br>Not at all, I will be honoured! <br><br><div>If you would like to know more about the project, I made a small write-up in PDF available here:<br></div><a href="https://github.com/tracek/Ornithokrites/blob/master/report/report.pdf?raw=true" target="_blank">https://github.com/tracek/<wbr>Ornithokrites/blob/master/<wbr>report/report.pdf?raw=true</a><br>
<br>The project's development page:<br><a href="https://github.com/tracek/Ornithokrites/" target="_blank">https://github.com/tracek/<wbr>Ornithokrites/</a><br><br><br>One more question related to aubio (energy) onset detection. In my early development version I was using 0.4.0alpha. Now that I switched to 0.4.1 some more onsets gets detected, in this case false positives. Did the algorithm get more sensitive? I tried tuning the threshold but no avail. I did not notice anything particular in the release notes. In the history of onsets you mention cleaning up and there is also this change:<br><br><pre>aubio_onset_set_delay<span class="x">_ms(o, 50.</span>);</pre>to:<br><pre><span class="n">aubio_onset_set_delay</span><span class="p">(</span><span class="n">o</span><span class="p">,</span> <span class="mf">4.3</span> <span class="o">*</span> <span class="n">hop_size</span><span class="p">);<br></span><br></pre>So making delay dependent on hop size. I tried compiling with old code, but actually got even more different results. Are there any fixes that could concern energy onset detection between 0.4.0alpha and 0.4.1? I was contemplating going back to alpha, but that is usually not a smart idea (probably it is just coincidence that alpha works temporarily better for my training set, perhaps a matter of tuning some other parameters than threshold).<br><br><br>Cheers,<br>Lucas<br></div> </div></body>
