如何从录音机流式传输音频并同时保存为音频文件?

当audioRecorder正在使用OkHttp录制时,我想将音频流传输到我的服务器。同时,我想录制的音频成为一个音频文件在本地安卓设备。

以下是我尝试的:

private void startRecordAudio() {
        audioRecorder = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE, CHANNEL,AUDIO_FORMAT, BUFFER_SIZE);
        audioRecorder.startRecording();
        recordingProgress.set(true);
        recordingThread = new Thread(new StreamRecordingRunnable(), "Stream Recording");
        recordingThread.start();
}

然后在 StreamRecordingRunnable() 我喜欢这样:

private class StreamRecordingRunnable implements  Runnable{

        @Override
        public void run() {
            final ByteBuffer buffer = ByteBuffer.allocateDirect(BUFFER_SIZE);

            RequestBody requestBody = new RequestBody() {
                @Nullable
                @Override
                public MediaType contentType() {
                    return MediaType.parse("audio/raw;encoding=signed-integer;bits=16;rate=8000;endian=little;");
                }

                @Override
                public void writeTo(@NonNull BufferedSink sink) throws IOException {
                    while(recordingProgress.get()){
                        int result = audioRecorder.read(buffer, BUFFER_SIZE);

                        if(result < 0){
                            Log.d(LOG_TAG, " Some streaming error here");

                        }else{
                            Log.d(LOG_TAG, " No problem here");
                            writeAudioDataToFile(); // Here I want to save the audio file before it send to server.
                            sink.write(buffer);
                            buffer.clear();
                        }

                    }
                }
            };
        

            Request request = httpRequestBuilder.post(requestBody).build();
            try(Response response = httpClient.newCall(request).execute()){
                if(response.isSuccessful()){
                    Log.v("OKHTTP", response.body().string());
                }else{
                    Log.d("http not successful", String.valueOf(response.body()));
                }

            }catch (IOException e){
                Log.d("HTTP", e.getMessage());
            }


        }
    }

完成以上所有代码后,我可以在录音机开始录音时发送音频文件。我可以在我的服务器中获取音频文件。

我现在想做的是:

制造 writeAudioDataToFile() 功能,我希望它存储的音频(将发送到服务器),到一个本地的Android设备内的本地文件。

这就是我想要的 writeAudioDataToFile() ,应存储在名为 audiotest12345.wav

    int BufferElements2Rec = 1024; // want to play 2048 (2K) since 2 bytes we use only 1024
    int BytesPerElement = 2;
    String filePath;

    private void writeAudioDataToFile() {
        // Write the output audio in byte

        filePath = getExternalCacheDir().getAbsolutePath();
        filePath += "/audiorecordtest12345.wav";

        short sData[] = new short[BufferElements2Rec];

        FileOutputStream os = null;
        try {
            os = new FileOutputStream(filePath);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        while (recordingProgress.get()) {
            // gets the voice output from microphone to byte format

            audioRecorder.read(sData, 0, BufferElements2Rec);
            System.out.println("Short wirting to file" + sData.toString());
            try {
                // // writes the data to file from buffer
                // // stores the voice buffer
                byte bData[] = short2byte(sData);
                os.write(bData, 0, BufferElements2Rec * BytesPerElement);

                Log.d("file name", filePath);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        try {
            os.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private byte[] short2byte(short[] sData) {
        int shortArrsize = sData.length;
        byte[] bytes = new byte[shortArrsize * 2];
        for (int i = 0; i < shortArrsize; i++) {
            bytes[i * 2] = (byte) (sData[i] & 0x00FF);
            bytes[(i * 2) + 1] = (byte) (sData[i] >> 8);
            sData[i] = 0;
        }
        return bytes;

    } 

结果:

但这样做,它不仅没有保存一个文件在本地,它也无法发送到服务器。我也试过这个:

private class StreamRecordingRunnable implements  Runnable{

        @Override
        public void run() {
            writeAudioDataToFile();
            final ByteBuffer buffer = ByteBuffer.allocateDirect(BUFFER_SIZE);

            //..all the RequestBody and networking call same as above
        }
}

如果我只做一个操作,意味着只保存文件或只发送到服务器,代码是工作的。但当我同时做的时候,它就不起作用了。

音频测试12345.wav 从 adb shell

这应该是因为1个麦克风中只有1个可能设备。但是我不知道我需要做什么才能同时完成这两项手术

因此,我的问题是:

1. 如何从录音机中保存音频文件并同时发送到服务器?

2. BufferedSink 价值?但我不知道怎么做,因为我是新来的 缓冲接收器 关于大雄,我不太明白这是怎么回事。

3. 因此,如果可能,请解释 也用于
