Class WavVectorDataSet

java.lang.Object
  org.das2.dataset.test.WavVectorDataSet

All Implemented Interfaces:

DataSet, VectorDataSet

public abstract class WavVectorDataSet
extends java.lang.Object
implements VectorDataSet

Wraps .wav file as a VectorDataSet. The dataset will have a set of data planes for each channel identified channel0, channel1, and so on. The x values are elapsed time, and the y units are dimensionless and normalized to 0.0 to +1.0.
