java.lang.Object

net.beadsproject.beads.data.audiofile.WavFileReaderWriter

All Implemented Interfaces:

AudioFileReader, AudioFileWriter

public class WavFileReaderWriter
extends java.lang.Object
implements AudioFileReader, AudioFileWriter

This class supports 'one-shot' reading and writing of wav files. It has no dependencies on 3rd party libraries so it should work on all platforms. Based on WavFile IO class by: A.Greensted (http://www.labbookpages.co.uk) This version has modified by: - Modified for use in the Beads library - Augmented to read and write 32- and 64-bit Floating Point PCM - Bugfixes File format is based on the information from - http://www.sonicspot.com/guide/wavefiles.html - http://www.blitter.com/~russtopia/MIDI/~jglatt/tech/wave.htm Version 1.0
