AnalyseEvents2 : UGen : AbstractFunction : Object
Extension
ExtensionDescription
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 Segmentation (for one-pass) and AnalyseEventsDatabase (for on-the-fly) classes in standard usage, don't use this directly.
Class Methods
AnalyseEvents2.ar(in, bufnum: 0, threshold: 0.34, triggerid: 101, circular: 0, pitch: 0)
Arguments:
| in |
Audio input to track |
| bufnum |
A buffer within which results of the analysis are place |
| threshold |
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) |
| triggerid |
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. |
| circular |
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. |
| pitch |
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. |
