我做了一个可以从我的电脑捕捉声音的小应用程序。系统的简单过程是当我播放音乐文件时，它会捕捉声音，当我播放捕捉到的东西时，它会播放。完全一切正常。现在我想做的是我想打印回放。假设我捕捉到像“嗨，早上好”这样的声音，现在当我按下播放时，它应该必须以文本形式打印录制的内容。捕获和回放编码如下。
private void captureAudio() {
try {
final AudioFormat format = getFormat();
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
final TargetDataLine line = (TargetDataLine) AudioSystem.getLine(info);
line.open(format);
line.start();
Runnable runner = new Runnable() {
int bufferSize = (int) format.getSampleRate() * format.getFrameSize();
byte buffer[] = new byte[bufferSize];
public void run() {
out = new ByteArrayOutputStream();
running = true;
try {
while (running) {
int count = line.read(buffer, 0, buffer.length);
if (count > 0) {
out.write(buffer, 0, count);
}
}
out.close();
} catch (IOException e) {
System.err.println("I/O problems: " + e);
System.exit(-1);
}
}
};
Thread captureThread = new Thread(runner);
captureThread.start();
} catch (LineUnavailableException e) {
System.err.println("Line unavailable: " + e);
System.exit(-2);
}
}
private void playAudio() {
try {
byte audio[] = out.toByteArray();
InputStream input = new ByteArrayInputStream(audio);
final AudioFormat format = getFormat();
final AudioInputStream ais = new AudioInputStream(input, format, audio.length / format.getFrameSize());
DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
final SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);
line.open(format);
line.start();
Runnable runner = new Runnable() {
int bufferSize = (int) format.getSampleRate() * format.getFrameSize();
byte buffer[] = new byte[bufferSize];
public void run() {
try {
int count;
while ((count = ais.read(buffer, 0, buffer.length)) != -1) {
if (count > 0) {
line.write(buffer, 0, (char)count);
System.out.print((char)count);
}
}
line.drain();
line.close();
} catch (IOException e) {
System.err.println("I/O problems: " + e);
System.exit(-3);
}
}
};
Thread playThread = new Thread(runner);
playThread.start();
} catch (LineUnavailableException e) {
System.err.println("Line unavailable: " + e);
System.exit(-4);
}
}
请有人建议/帮助我克服这一点。
谢谢你。
