从电脑文件播放在java中的.wav文件

问题描述

package soundTest;

import java.applet.*;
import java.net.*;
import javax.swing.*;
import javax.sound.sampled.*;
import java.io.*;
import java.util.*;

public class SoundTest {

public static void main(String[] args) throws Exception {

    try {
        AudioClip clip1 = Applet.newAudioClip(new URL(new File("E0.wav").getAbsolutePath()));
        clip1.play();
    } catch (MalformedURLException murle) {
        System.out.println(murle);
    }

    URL url = new URL(
            "http://www.mediafire.com/listen/tok9j9s1hnogj1y/downloads/E0.wav");
    Clip clip = AudioSystem.getClip();
    AudioInputStream ais = AudioSystem.getAudioInputStream(url);
    clip.open(ais);

    URL url2 = new URL(
            "http://www.villagegeek.com/downloads/webwavs/Austin_Powers_death.wav");
    Clip clip2 = AudioSystem.getClip();
    AudioInputStream ais2 = AudioSystem.
            getAudioInputStream(url2);
    clip2.open(ais2);
    clip.loop(1);
    clip2.loop(Clip.LOOP_CONTINUOUSLY);

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JOptionPane.showMessageDialog(null, "Close to exit!");
        }
    });
}

}

我无法弄清楚如何从我的电脑（而不是从URL）在Java中发挥wav文件。我敢肯定，我把它放置在右侧区域中，SRC（我也把它放在几乎所有其他的空间，以防万一......）。

I can't figure out how to play a wav file from my computer (not from a URL) in java. I'm sure that I have it placed in the right area, the SRC (I also placed it in practically every other space just in case...).

第一次尝试从
它使我的catch语句。

The first attempt is from http://www.cs.cmu.edu/~illah/CLASSDOCS/javasound.pdfIt gives the me the catch statement.

第二次尝试把我的记录.wav文件的主人MediaFire。但是，没有工作。 异常线程mainjavax.sound.sampled.UnsupportedAudioFileException：无法从输入网址音频输入流

The second attempt was putting my recorded .wav file on mediafire. However, that didn't work. "Exception in thread "main" javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input URL"

第三个例子工作正常，但不像我的文件，它是从网上的文件。当你点击一个，它带给你的只是一个音频播放器，而主人MediaFire链接带给你与其他的东西和一些应用可以播放该文件的网页。

The third example works fine, but, unlike my file, it's a file from online. When you click on that one, it brings you to just an audio player, while the mediafire link brings you to a page with other stuff and some application that plays the file.

推荐答案

第一次尝试

AudioClip clip1 = Applet.newAudioClip(new URL(new File("E0.wav").getAbsolutePath()));

这是不是你如何构建一个网​​址到文件。相反，你应该使用文件＃getURI＃的getURL

This is not how you construct a URL to a File. Instead, you should use File#getURI#getURL

AudioClip clip1 = Applet.newAudioClip(new File("/full/path/to/audio.wav").toURI().toURL());

第二次尝试

主人MediaFire返回一个HTML响应，而不是音频文件......你可以......测试

mediafire is returning a html response, not the audio file...You can test it with...

URL url = new URL("http://www.mediafire.com/listen/tok9j9s1hnogj1y/downloads/E0.wav");
try (InputStream is = url.openStream()) {
    int in = -1;
    while ((in = is.read()) != -1) {
        System.out.print((char)in);
    }
} catch (IOException exp) {
    exp.printStackTrace();
}

第三次尝试

您打开片段，但从来没有启动吧...

You open the clip, but never start it...

URL url2 = new URL("http://www.villagegeek.com/downloads/webwavs/Austin_Powers_death.wav");
Clip clip2 = AudioSystem.getClip();
AudioInputStream ais2 = AudioSystem.getAudioInputStream(url2);
clip2.open(ais2);
clip2.start();
