Constructor Detail

WavBuffer

public WavBuffer(byte[] content)

Create from already existing byte array. The array is expected to be in .wav format, starting with a RIFF header.

IOException

Method Detail

findHeader

public int findHeader(int i1,
                      int i2,
                      int i3,
                      int i4)

Find a specific header in the .wav fragment

Returns:

offset of the 1st byte of the header in the buffer

getSampleRate

public float getSampleRate()

getSampleSizeInBits

public int getSampleSizeInBits()

getChannels

public int getChannels()

getBigEndian

public boolean getBigEndian()

getSigned

public boolean getSigned()

getDataStart

public int getDataStart()

Offset to the first data byte in the buffer

getDataSize

public int getDataSize()

Size of the data segment in bytes

getDataEnd

public int getDataEnd()

Offset to the last data byte in the buffer. One more than this points to the next header.

getByteArray

public byte[] getByteArray()
