在java中录制流媒体音频？

import javax.sound.sampled.*;

public class AudioRecorder {
    public static void main(String[] args) {
        try {
            AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100, 16, 2, 4, 44100, false);
            Mixer.Info[] mixerInfos = AudioSystem.getMixerInfo();
            Mixer mixer = AudioSystem.getMixer(mixerInfos[0]);
            TargetDataLine line = (TargetDataLine) mixer.getLine(new DataLine.Info(TargetDataLine.class, format));
            line.open(format);
            line.start();

            int bufferSize = 4096;
            byte[] buffer = new byte[bufferSize];

            File outputFile = new File("output.wav");
            AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;
            AudioInputStream audioInputStream = new AudioInputStream(line);
            AudioSystem.write(audioInputStream, fileType, outputFile);
        } catch (LineUnavailableException | IOException e) {
            e.printStackTrace();
        }
    }
}
