Java8で音声ファイル(RAW,WAV,MP3)を再生する方法

Main

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;
import javazoom.jl.decoder.JavaLayerException;

public class SoundPlayTest {

    public static void main(String[] args) throws LineUnavailableException, IOException, JavaLayerException, UnsupportedAudioFileException {

        RawPlayer rawPlayer = new RawPlayer();
        rawPlayer.play(new FileInputStream(new File("sample.wav")));

        Mp3Player mp3Player = new Mp3Player();
        mp3Player.play(new FileInputStream(new File("sample.mp3")));

        WavPlayer wavPlayer = new WavPlayer();
        wavPlayer.play(new FileInputStream(new File("sample.wav")));

    }

}

RAW

import java.io.BufferedInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioSystem;

import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;

public class RawPlayer {

    private byte buf[] = new byte[1024];
    private int len;

    public void play(InputStream rawfile) throws LineUnavailableException, FileNotFoundException, IOException {
        BufferedInputStream raw = new BufferedInputStream(rawfile);
        AudioFormat format = new AudioFormat(8000, 16, 1, true, false);
        // select audio format parameters
        DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
        SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);
        // prepare audio output
        line.open(format, 1024);
        line.start();
        // play audio
        while ((len = raw.read(buf)) != -1)
            line.write(buf, 0, len);
        // shut down audio
        line.drain();
        line.stop();
        line.close();

    }

MP3

public class Mp3Player {

    public void play(InputStream mp3file) throws JavaLayerException {

        AudioDevice device = FactoryRegistry.systemRegistry().createAudioDevice();
        // create an MP3 player
        AdvancedPlayer player = new AdvancedPlayer(mp3file, device);
        player.setPlayBackListener(new PlaybackListener() {
            @Override
            public void playbackStarted(PlaybackEvent evt) {
                out.println("[Playback] started.");
            }
            @Override
            public void playbackFinished(PlaybackEvent evt) {
                out.println("[Playback] finished.");
            }
        });
        // play it!
        player.play();
    }

}

WAV

public class WavPlayer {

    private byte buf[] = new byte[1024];
    private int len;

    public void play(InputStream wavfile) throws UnsupportedAudioFileException, IOException, LineUnavailableException {

        AudioInputStream wav = AudioSystem.getAudioInputStream(wavfile);
        AudioFormat format = wav.getFormat();
        // prepare audio output
        DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
        SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);
        // prepare audio output
        line.open(format, 1024);
        line.start();
        // play audio
        while ((len = wav.read(buf)) != -1)
            line.write(buf, 0, len);
        // shut down audio
        line.drain();
        line.stop();
        line.close();
    }

}

MP3の再生にはJavaZOOMを使っています。
