当我点击" console stop"时,我写的代码并没有停止录制。我不明白我做错了什么。你能看一下下面的代码并建议我的错误在哪里吗?
这是:
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
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.LineUnavailableException;
import javax.sound.sampled.TargetDataLine;
public class Main {
final static int MONO = 1;
private static AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;
public static void main(String[] args) {
AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
16000, 16, MONO, 2, 16000, true);
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
int numb = 1;
String files = "C:\\test\\music\\lala" + numb + "." + fileType;
File fileOut = new File(files);
if (!AudioSystem.isLineSupported(info)) {
System.out.println("Line nit supporot!");
}
System.out.println("To stop recording a sound lead - stop");
Scanner sc = new Scanner(System.in);
String scc;
TargetDataLine mike = null;
try {
mike = (TargetDataLine) AudioSystem.getLine(info);
mike.open(format);
AudioInputStream sound = new AudioInputStream(mike);
mike.start();
AudioSystem.write(sound, fileType, fileOut);
scc = sc.nextLine();
if (scc.equals("stop")) {
System.out.println("recording is stopped!");
mike.stop();
sound.close();
System.exit(0);
}
} catch (LineUnavailableException e) {
System.out.println("line not avaible");
} catch (IOException e) {
e.printStackTrace();
}
}
}
不起作用:
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
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.LineUnavailableException;
import javax.sound.sampled.TargetDataLine;
public class Main implements Runnable {
final static int MONO = 1;
private static AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;
private static TargetDataLine mike;
private static AudioInputStream sound;
public static void main(String[] args) {
AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
16000, 16, MONO, 2, 16000, true);
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
int numb = 1;
String files = "C:\\test\\music\\lala" + numb + "." + fileType;
File fileOut = new File(files);
if (!AudioSystem.isLineSupported(info)) {
System.out.println("Line nit supporot!");
}
System.out.println("Для остановки записи звука введите - g");
try {
mike = (TargetDataLine) AudioSystem.getLine(info);
mike.open(format);
sound = new AudioInputStream(mike);
mike.start();
AudioSystem.write(sound, fileType, fileOut);
} catch (LineUnavailableException e) {
System.out.println("line not avaible");
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void run() {
Scanner sc = new Scanner(System.in);
String scc;
scc = sc.nextLine();
if (scc.equals("g")) {
System.out.println("Запись звука остановлена");
mike.stop();
try {
sound.close();
} catch (IOException e) {
e.printStackTrace();
}
System.exit(0);
}
}
}
答案 0 :(得分:0)
从目前为止我们可以看到,上面的实现缺少一大段代码。你似乎正在捕捉这条线(我还没有尝试过运行或调试上面的内容),但是没有任何显示你实际从那条线读取数据的地方!
如果您参考Java教程中的示例,请参阅教程中的部分"捕获音频"标题为Reading the Data from the TargetDataLine的代码显示了此过程的代码。注意使用boolean"!stopped"。此布尔值可用于停止从外部线程读取的while循环,例如按下按钮的结果。为了获得最佳性能,布尔值应指定为volatile,并提供一个公共方法,允许您将其值设置为' false'。
