我正在尝试使用Java播放* .wav文件。我希望它执行以下操作: 按下按钮时,播放一声短促的哔声。
我已经用谷歌搜索了,但是大多数代码都没有用。有人可以给我一个简单的代码片段来播放.wav文件吗?
没有Java反射的解决方案 DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat)
DataLine.Info info = new DataLine.Info(SourceDataLine.class
audioFormat
Java反射会降低性能。跑步:java playsound absoluteFilePathTo/file.wav
java playsound absoluteFilePathTo/file.wav
import javax.sound.sampled.*; import java.io.*; public class playsound { public static void main (String args[]) throws Exception { playSound (args[0]); } public static void playSound () throws Exception { AudioInputStream audioStream = AudioSystem.getAudioInputStream(new File (filename)); int BUFFER_SIZE = 128000; AudioFormat audioFormat = null; SourceDataLine sourceLine = null; audioFormat = audioStream.getFormat(); sourceLine = AudioSystem.getSourceDataLine(audioFormat); sourceLine.open(audioFormat); sourceLine.start(); int nBytesRead = 0; byte[] abData = new byte[BUFFER_SIZE]; while (nBytesRead != -1) { try { nBytesRead = audioStream.read(abData, 0, abData.length); } catch (IOException e) { e.printStackTrace(); } if (nBytesRead >= 0) { int nBytesWritten = sourceLine.write(abData, 0, nBytesRead); } } sourceLine.drain(); sourceLine.close(); } }
最后,我设法做到了以下几点,并且工作正常
import java.io.File; import java.io.IOException; import javax.sound.sampled.AudioFormat; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import javax.sound.sampled.DataLine; import javax.sound.sampled.LineUnavailableException; import javax.sound.sampled.SourceDataLine; public class MakeSound { private final int BUFFER_SIZE = 128000; private File soundFile; private AudioInputStream audioStream; private AudioFormat audioFormat; private SourceDataLine sourceLine; /** * @param filename the name of the file that is going to be played */ public void playSound(String filename){ String strFilename = filename; try { soundFile = new File(strFilename); } catch (Exception e) { e.printStackTrace(); System.exit(1); } try { audioStream = AudioSystem.getAudioInputStream(soundFile); } catch (Exception e){ e.printStackTrace(); System.exit(1); } audioFormat = audioStream.getFormat(); DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat); try { sourceLine = (SourceDataLine) AudioSystem.getLine(info); sourceLine.open(audioFormat); } catch (LineUnavailableException e) { e.printStackTrace(); System.exit(1); } catch (Exception e) { e.printStackTrace(); System.exit(1); } sourceLine.start(); int nBytesRead = 0; byte[] abData = new byte[BUFFER_SIZE]; while (nBytesRead != -1) { try { nBytesRead = audioStream.read(abData, 0, abData.length); } catch (IOException e) { e.printStackTrace(); } if (nBytesRead >= 0) { @SuppressWarnings("unused") int nBytesWritten = sourceLine.write(abData, 0, nBytesRead); } } sourceLine.drain(); sourceLine.close(); } }
