AttackSlope : MultiOutUGen : UGen : AbstractFunction : Object
Extension
ExtensionDetect onsets and assess the nature of the attack slope
Source: AttackSlope.sc
Description
Detects onsets using an energy based detection function, and then assesses the nature of the attack slope in various ways.
Class Methods
AttackSlope.kr(input, windowsize: 1024, peakpicksize: 20, leak: 0.999, energythreshold: 0.01, sumthreshold: 20, mingap: 30, numslopesaveraged: 10)
control rate feature extraction
Arguments:
| input |
audio input |
| windowsize |
Size in samples of the operating window for detection |
| peakpicksize |
parameter of onset detection |
| leak |
parameter of onset detection |
| energythreshold |
parameter of onset detection |
| sumthreshold |
parameter of onset detection |
| mingap |
Do not retrigger for detected onsets unless this number of control periods has elapsed |
| numslopesaveraged |
number of slopes to average (number of previous slopes to store) |
Returns:
(describe returnvalue here) //[0] onset trigger (can be used as an onset detector) //[1] corrected to minima time of last onset //[2] most recent slope measurement //[3] average slope calculation //[4] raw detection function //[5] raw peakpick function
