StdDevUGen is a pseudo UGen that calculates the standard deviation of a signal over a specified time window.
It takes the square root of the VarianceUGen
Class Methods
.kr
Calculates the standard deviation on a control rate signal.
Arguments:
| input |
The signal to calculate the standard deviation of. |
| length |
The length in samples of the window |
| mean |
If you already calculate a mean (=RunningSum/length) in another part of your SynthDef you can supply it here, so it is not calculated again, thus safing processing power. |
