Thread: Change the pitch in a jButton

I am trying to change the pitch of a wave file while mouse entering a JButton. the problem is the JButton object doesn't support the SAMPLE_RATE control. what can I do to change the pitch?

I am trying to play a wave file when the mouse enters different JButton objects. on the MouseEntered events I call this function:

public void playSound(String fileName) {
		audioInputStream = null;
		File soundFile;
		soundFile = new File(fileName);
		SourceDataLine auline = null;
		if (!soundFile.exists()) {
			System.err.println("Wave file not found: " + soundFile);
			return;
		}
		try {
			audioInputStream = AudioSystem.getAudioInputStream(soundFile);
		} catch (UnsupportedAudioFileException e1) {
			e1.printStackTrace();
			return;
		} catch (IOException e1) {
			e1.printStackTrace();
			return;
		}
 
		AudioFormat format = audioInputStream.getFormat();
		DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
 
		try {
			auline = (SourceDataLine) AudioSystem.getLine(info);
			auline.open(format);
		} catch (LineUnavailableException e) {
			e.printStackTrace();
			return;
		} catch (Exception e) {
			e.printStackTrace();
			return;
		}
//////////////////////// here I would like to change the pitch of the sound///////////////////////////////////////////////////////////////////////////
		auline.start();
		int nBytesRead = 0;
		byte[] abData = new byte[EXTERNAL_BUFFER_SIZE];
 
		try {
			while (nBytesRead != -1) {
				nBytesRead = audioInputStream.read(abData, 0, abData.length);
				if (nBytesRead >= 0)
					auline.write(abData, 0, nBytesRead);
			}
		} catch (IOException e) {
			e.printStackTrace();
			return;
		} finally {
			auline.drain();
			auline.close();
			auline = null;
			try {
				audioInputStream.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}

I tried using: (auline.isControlSupported(FloatControl.Type.SAMPL E_RATE)) but I the control is not supported.


thank you!
