Class Methods
OnsetStatistics.kr(input, windowsize: 1.0, hopsize: 0.1)
Operate feature extraction at control rate
Arguments:
| input |
Triggers at the control rate input are stored with their associated time of activation |
| windowsize |
Size of operating window (from now into the past) in seconds. Any onset triggers within this time are taken into account |
| hopsize |
Not used at present, re-calculates every block |
Returns:
(describe returnvalue here) [0] Density of onsets (number of triggers) in the window [1] Mean of IOIs (in seconds) [2] Standard deviation of IOIs
