从使用Java的URL获取声音 [英] Get sound from a URL with Java

问题描述

我学英语，我想开发一个软件来帮助我的发音。

I'm learning english and I'd like to develop a software to help me with the pronunciation.

有一个名为HowJSay网站，如果你在这里输入： HTTP：// WWW。 howjsay.com/index.php?word=car
立刻，你会听到字车的发音。我想用Java开发一个软件，可以玩这个声音没有在网站上输入的必要性=]

There is a site called HowJSay, if you enter here: http://www.howjsay.com/index.php?word=car immediatly you'll hear the pronunciation of the word car . I'd like to develop a software in JAVA that could play this sound without necessity of enter in the site =]

我想这一点，但不工作= /

I tried this, but doesn't work =/

public static void main(String[] args) throws Exception {
    URL url = new URL("http://www.howjsay.com/index.php?word=car");
    url.openConnection();
    AudioStream as = new AudioStream(url.openStream());
    AudioPlayer.player.start(as);
    AudioPlayer.player.stop(as);
}

任何想法？请。

推荐答案

在这里你去

import javax.sound.sampled.*;
import java.io.IOException;
import java.net.URL;

public class HowJSay
{
public static void main(String[] args) {
    AudioInputStream din = null;
    try {
        AudioInputStream in = AudioSystem.getAudioInputStream(new URL("http://www.howjsay.com/mp3/"+ args[0] +".mp3"));
        AudioFormat baseFormat = in.getFormat();
        AudioFormat decodedFormat = new AudioFormat(
                AudioFormat.Encoding.PCM_SIGNED,
                baseFormat.getSampleRate(), 16, baseFormat.getChannels(),
                baseFormat.getChannels() * 2, baseFormat.getSampleRate(),
                false);
        din = AudioSystem.getAudioInputStream(decodedFormat, in);
        DataLine.Info info = new DataLine.Info(SourceDataLine.class, decodedFormat);
        SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);
        if(line != null) {
            line.open(decodedFormat);
            byte[] data = new byte[4096];
            // Start
            line.start();

            int nBytesRead;
            while ((nBytesRead = din.read(data, 0, data.length)) != -1) {
                line.write(data, 0, nBytesRead);
            }
            // Stop
            line.drain();
            line.stop();
            line.close();
            din.close();
        }

    }
    catch(Exception e) {
        e.printStackTrace();
    }
    finally {
        if(din != null) {
            try { din.close(); } catch(IOException e) { }
        }
    }
}

}
