Constructor Detail

TAudioOutputStream

protected TAudioOutputStream(AudioFormat audioFormat,
                             long lLength,
                             TDataOutputStream dataOutputStream,
                             boolean bDoBackPatching)

Method Detail

requireSign8bit

protected void requireSign8bit(boolean signed)

descendants should call this method if implicit sign conversion for 8-bit data should be done

requireEndianness

protected void requireEndianness(boolean bigEndian)

descendants should call this method if implicit endian conversion should be done. Currently supported for 16, 24, and 32 bits per sample.

getFormat

public AudioFormat getFormat()

Description copied from interface: AudioOutputStream

Retrieves the AufioFormat of this AudioOutputStream.

Specified by:

getFormat in interface AudioOutputStream

getLength

public long getLength()

Gives length of the stream. This value is in bytes. It may be AudioSystem.NOT_SPECIFIED to express that the length is unknown.

Specified by:

getLength in interface AudioOutputStream

getCalculatedLength

public long getCalculatedLength()

Gives number of bytes already written.

getDataOutputStream

protected TDataOutputStream getDataOutputStream()

write

public int write(byte[] abData,
                 int nOffset,
                 int nLength)
          throws IOException

Writes audio data to the destination (file or output stream).

Specified by:

write in interface AudioOutputStream

Throws:

IOException

writeHeader

protected abstract void writeHeader()
                             throws IOException

Writes the header of the audio file.

Throws:

IOException

close

public void close()
           throws IOException

Closes the stream. This does write remaining buffered data to the destination, backpatch the header, if necessary, and closes the destination.

Specified by:

close in interface AudioOutputStream

Throws:

IOException

patchHeader

protected void patchHeader()
                    throws IOException

Throws:

IOException

setLengthFromCalculatedLength

protected void setLengthFromCalculatedLength()
