com.groovemanager.sampled.waveform
Class ByteArrayWaveForm

java.lang.Object
  com.groovemanager.sampled.waveform.AbstractWaveForm
      com.groovemanager.sampled.waveform.ByteArrayWaveForm

All Implemented Interfaces:

WaveForm

public class ByteArrayWaveForm

extends AbstractWaveForm

A ByteArrayWaveForm reads its displayable data directly from a given array of audio data. This can be very memory consuming so that ByteArrayWaveForms should only be used for small amounts of audio data. This implementation will only read the most signifigant byte of each sample. For AudioFormats where this byte doesn´t represent more or less the real amplitude, this implementation should not be used.
