net.beadsproject.beads.ugens.RMS
public class RMS
Calculates and outputs the RMS (root-mean-squares) power factor for a signal over a given time frame. The algorithm accounts for multi-channel input by summing the squares of each channel and dividing by the square root of the number of channels.

public void calculateBuffer()
UGen
UGen.bufIn
and putting data
into UGen.bufOut
in some way. UGen.bufIn
and UGen.bufOut
are 2D arrays of floats of the form float[numChannels][bufferSize]. The length of the buffers is given by
UGen.bufferSize
, and the number of channels of the input and output buffers are given by UGen.ins
and UGen.outs
respectively.
