|
6272 |
+A phaser filter creates series of peaks and troughs in the frequency spectrum. |
|
6273 |
+The position of the peaks and troughs are modulated so that they vary over time, creating a sweeping effect. |
|
6274 |
+ |
|
6275 |
+The filter accepts parameters as a list of @var{key}=@var{value} |
|
6276 |
+pairs, separated by ":". |
|
