Fc9-type-16-icon.png Connect To
DSP component with output buffer to collect our data from. 
Fc9-type-21-icon.png Buffer Size
Number of individual elements the buffer can store, default 1. 
Fc9-type-16-icon.png Buffer Type
Sets the buffer data type. 
Fc9-conn-icon.png Median Array
Fc9-type-14-icon.png Median Array Size
The number of values to combine together to create the median effect. Default 5. The higher the number the more immune to spikes the data will be. A larger array requires more processing to order. Minimum 3, maximum 255.
