Program Java untuk Memainkan File Suara WAV

Bro 'n Sis... berikut saya tampilkan source code program Java untuk memainkan file audio suara berformat WAV. Program ini didapatkan dari hasil pencarian di internet lalu diedit sana-sini biar bisa berfungsi.

Untuk menjalankannya tinggal membuat objek di class lain dengan perintah :

new dengarWav("alamat_asli.wav").start();

WARNING :

• hanya support file .wav. Format .mp3 atau .ogg tidak bisa.
• kalau dijalankan langsung dari NetBeans tidak bisa. Pasti bilangnya : file tidak ditemukan.
• jadi jalankan melalui konsol dengan perintah : java namaClass.... OK!

Berikut source code program Java untuk memainkan file audio / suara dengan format .wav tinggal di-copas sajalah :

import java.io.File;
import java.io.IOException;

public class dengarWav extends Thread {

  private String filename;

  private Position curPosition;

  private final int EXTERNAL_BUFFER_SIZE = 524288; // 128Kb

  enum Position {
      LEFT, RIGHT, NORMAL
  };

  public dengarWav(String wavfile) {
      filename = wavfile;
      curPosition = Position.NORMAL;
  }

  public dengarWav(String wavfile, Position p) {
      filename = wavfile;
      curPosition = p;
  }

  @Override
  public void run() {

      File soundFile = new File(filename);
      if (!soundFile.exists()) {
          System.err.println("File WAV ilang : " + filename);
          return;
      }

      AudioInputStream audioInputStream = null;
      try {
          audioInputStream = AudioSystem.getAudioInputStream(soundFile);
      } catch (UnsupportedAudioFileException e1) {
          //e1.printStackTrace();
          return;
      } catch (IOException e1) {
          //e1.printStackTrace();
          return;
      }

      AudioFormat format = audioInputStream.getFormat();
      SourceDataLine auline = null;

          auline.open(format);
      } catch (LineUnavailableException e) {

          return;
      } catch (Exception e) {
          //e.printStackTrace();
          return;
      }

      if (auline.isControlSupported(FloatControl.Type.PAN)) {
          FloatControl pan = (FloatControl) auline.getControl(FloatControl.Type.PAN);
          if (curPosition == Position.RIGHT)
              pan.setValue(1.0f);
          else if (curPosition == Position.LEFT)
              pan.setValue(-1.0f);
      }

      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();
      }

  }
