我不确定你真正想要的是什么，但也许this answer可以帮助你。还要阅读原始问题，以确保它与您遇到的问题相同。

尝试以下代码：

 String hostname = "192.168.1.10";
int port = 8000;
Socket socket = null;
    try {
        socket = new Socket(InetAddress.getByName(hostname), port);
    } catch (UnknownHostException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);

recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(pfd.getFileDescriptor());

    try {
        recorder.prepare();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

recorder.start();
