	MedianArray
Passes an entire buffer through the median buffer and spits out a filtered version of the data at the other end
- VOID	Return

	Median
Passes a single value from a DSP buffer into the median buffer and spits out a median value at the other end
- VOID	Return

	ReadAverageArray
Returns the average from the last "Decay" number of buffers.
- UINT	Return

	ReadPeak
Returns the highest value from the last "Decay" number of index locations.
[[File:]] -	Return

Property reference

	Properties
	Connect To
DSP component with output buffer to collect our data from.
	Buffer Size
Number of individual elements the buffer can store, default 1.
	Buffer Type
Sets the buffer data type.
	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.
