Java音频录制示例

一个简易的Java音频录制例程，可录制时长为10秒的wav音频。

import java.io.File;
import java.util.concurrent.TimeUnit;
import javax.sound.sampled.AudioFileFormat;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.TargetDataLine;

public class AudioRecode {

	public static void recode() throws Exception {
		String path = "D:\\test\\first.wav";
		//AudioFormat(encoding, sampleRate, sampleSizeInBits, channels, frameSize, frameRate, bigEndian)
		AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100, 16, 2, 4, 44100, true);
		DataLine.Info info = new DataLine.Info(TargetDataLine.class,format); //,AudioSystem.NOT_SPECIFIED
		TargetDataLine tDataLine = (TargetDataLine)AudioSystem.getLine(info);
		tDataLine.open(format);
		tDataLine.start();
		
		Thread audioThd = new Thread(new Runnable() {
			@Override
			public void run() {
                AudioInputStream in = new AudioInputStream(tDataLine);
                try {
                    System.out.println("开始录音");
                    File saveFile = new File(path);
                    AudioSystem.write(in, AudioFileFormat.Type.WAVE, saveFile);
                    
                } catch (Exception e) {
                    e.printStackTrace();
                    return;
                }
			}
		});
		audioThd.start();
		TimeUnit.SECONDS.timedJoin(audioThd, 10);//录音时长
		if (audioThd.isAlive()){
            audioThd.interrupt();
        }
		System.out.println("录音结束");
	}
	public static void main(String[] args) throws Exception {
		recode();
	}

}

若觉得这个例程太简陋。下面再推荐一个CSDN博主「程序员小牧之」的“Java音频录制和播放”的博文：Java音频录制和播放
