<p>On-the-fly event analyser, based on onset detection/on-the-fly analysis described in my academic papers. Best for percussive events. Recommended that you go via the <a href="./../Classes/Segmentation.html">Segmentation</a> (for one-pass) and <a href="./../Classes/AnalyseEventsDatabase.html">AnalyseEventsDatabase</a> (for on-the-fly) classes in standard usage, don't use this directly.<div class='note'><span class='notelabel'>NOTE:</span> you will need bbcut2 for further classes and capabilities. This UGen is included in sc3-plugins for cross-platform building.</div><h2><a class='anchor' name='classmethods'>Class Methods</a></h2>

|

|
<p>A parameter acting as the onset detector threshold, default of 0.34 was determined as the best performing over a database of percussive onset, but you might want to change this to change the sensitivity (though you always increase the risk of false positives or false negatives)<tr><td class='argumentname'>triggerid<td class='argumentdesc'>
|
||
|
|
<p>A trigger ID number used for communication from the UGen to the Lang to mark that a new event was received. Only passed for on-the-fly analysis.<tr><td class='argumentname'>circular<td class='argumentdesc'>
|
||
|
|
<p>A flag to note on-the-fly analysis assuming a circular buffer. If you only need a one-pass analysis on a file, you won't use this.<tr><td class='argumentname'>pitch<td class='argumentdesc'>
|
||
|
|
<p>Can take a .kr pitch detection UGen as input. Will take the median fundamental frequency over a note event from values recorded from this pitch input.</table></div><h3><a class='anchor' name='Inherited%20class%20methods'>Inherited class methods</a></h3>
