Method Detail

handleForm

public void handleForm(com.jsyn.util.soundfile.IFFParser parser,
                       int ckID,
                       int ckSize,
                       int type)
                throws java.io.IOException

Called by parse() method to handle FORM chunks in an AIFF specific manner.

Parameters:

ckID - four byte chunk ID such as 'data'

ckSize - size of chunk in bytes

Throws:

java.io.IOException - If parsing fails, or IO error occurs.

handleChunk

public void handleChunk(com.jsyn.util.soundfile.IFFParser parser,
                        int ckID,
                        int ckSize)
                 throws java.io.IOException

Called by parse() method to handle chunks in an AIFF specific manner.

Parameters:

ckID - four byte chunk ID such as 'data'

ckSize - size of chunk in bytes

Throws:

java.io.IOException - If parsing fails, or IO error occurs.

getDataPosition

public long getDataPosition()

Returns:

Number of bytes from beginning of stream where sound data resides.

getNumBytesRead
