Question

我想在使用Java进行无限流识别期间录制语音

我试图录制其他线程的声音，但是重复的音频线会导致严重错误

这是我的语音记录代码

Runnable r = new Runnable() {

    @Override
    public void run() {
        try {
            AudioFormat format = getAudioFormat();
            DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);

            // checks if system supports the data line
            if (!AudioSystem.isLineSupported(info)) {
                System.out.println("Line not supported");
                System.exit(0);
            }
            line = (TargetDataLine) AudioSystem.getLine(info);
            line.open(format);
            line.start(); // start capturing
            System.out.println("Start capturing...");

            AudioInputStream ais = new AudioInputStream(line);

            System.out.println("Start recording...");

            // start recording
            AudioSystem.write(ais, fileType, wavFile);

        } catch (LineUnavailableException ex) {
            ex.printStackTrace();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }

    }
};

这是我的语音记录设置代码 AudioFormat getAudioFormat() { float sampleRate = 16000; int sampleSizeInBits = 16; int channels = 1; boolean signed = true; boolean bigEndian = false; AudioFormat format = new AudioFormat(sampleRate, sampleSizeInBits, channels, signed, bigEndian); return format; } javax.sound.sampled.LineUnavailableException：格式为PCM_SIGNED 16000.0 Hz的行，16位，单声道，2字节/帧，不支持little-endian。
