close in interface AudioOutputStream

Throws:

java.io.IOException

write

public void write(double[] buffer)
           throws java.io.IOException

Write audio to the WAV file.

Specified by:

write in interface AudioOutputStream

Throws:

java.io.IOException

write

public void write(double value)
           throws java.io.IOException

Write audio to the WAV file.

Specified by:

write in interface AudioOutputStream

Throws:

java.io.IOException

write

public void write(double[] buffer,
         int start,
         int count)
           throws java.io.IOException

Write audio to the WAV file.

writeIntLittle

public void writeIntLittle(int n)
                    throws java.io.IOException

Write a 32 bit integer to the stream in Little Endian format.

Throws:

java.io.IOException

writeShortLittle

public void writeShortLittle(short n)
                      throws java.io.IOException

Write a 16 bit intgeer to the stream in Little Endian format.

Throws:

java.io.IOException

writeFormatChunk

public void writeFormatChunk()
                      throws java.io.IOException

Write an 'fmt ' chunk to the WAV file containing the given information.

Throws:

java.io.IOException

writeDataChunkHeader

public void writeDataChunkHeader()
                          throws java.io.IOException

Write a 'data' chunk header to the WAV file. This should be followed by call to writeShortLittle() to write the data to the chunk. If you do not know the length of the data chunk when calling this method, then pass zero for the size. Then when you finish writing the data call fixSizes().

Throws:

java.io.IOException
