Constructor Detail

ZeroCross

public ZeroCross(AudioContext context,
                 float memSizeInMS)

Constructor. The specified memory size indicates the time frame over which zero crossings are counted.

Parameters:

context - The audio context.

memSizeInMS - The time frame in milliseconds.

Method Detail

calculateBuffer

public void calculateBuffer()

Description copied from class: UGen

Called by the signal chain to update this UGen's ouput data. Subclassses of UGen should implement the UGen's DSP perform routine here. In general this involves grabbing data from 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.

Specified by:

calculateBuffer in class UGen

getMemorySize

public float getMemorySize()

Gets the memory size.

Returns:

The memory size in milliseconds.
