AudioTrack.write

Question

我正在使用AudioTrack库来播放通过wifi流式传输的pcm样本。问题是在 Lenovo K900（4.1.2）上播放时播放非常不稳定，而在 OnePlusOne（Marshmallow 6.0.1 cyanogen）手机上播放时则无缝播放。 为了排除流延迟，我首先将整个流加载到一个数组中，然后通过循环遍历预先填充的数组来播放音频。仍有事情根本没有改善。 现在 K900 正在运行 Android 4.1.2 而我使用的android sdk是用于 API23 ，我的意思是当我打开AudioTrack类的定义时打开 API23 的类文件。这会引起任何问题吗？

               int bufferSize = AudioTrack.getMinBufferSize(SAMPLE_RATE, AudioFormat.CHANNEL_OUT_MONO,
                        AudioFormat.ENCODING_PCM_8BIT);
                if (bufferSize == AudioTrack.ERROR || bufferSize == AudioTrack.ERROR_BAD_VALUE) {
                    bufferSize = SAMPLE_RATE * 2;
                }
                int readBytes;
                int bufSize=2123880;//size of the file being streamed
                byte[] buffer=new byte[bufSize];
                //bufferSize*=2;
                DataInputStream in = new DataInputStream(socket.getInputStream());
                readBytes=0;
                while(true) {
                    try {
                        if(in.available()>0){
                            readBytes+=in.read(buffer, readBytes, in.available());
                        //    audioTrack.write(buffer,0,readBytes);
                        }else{
                            break;
                        }
                    } catch (SocketTimeoutException s) {
                        System.out.println("Socket timed out!");
                        //audioTrack.release();
                        break;
                    } catch (IOException e) {
                        e.printStackTrace();
                        //audioTrack.release();
                        break;
                    }
                }
                in.close();
                readBytes=0;
                AudioTrack audioTrack = new AudioTrack(
                        AudioManager.STREAM_MUSIC,
                        SAMPLE_RATE,
                        AudioFormat.CHANNEL_OUT_MONO,
                        AudioFormat.ENCODING_PCM_8BIT,
                        bufferSize,
                        AudioTrack.MODE_STREAM);
                audioTrack.play();
                while(readBytes<bufSize){
                    readBytes+=audioTrack.write(buffer,readBytes,bufferSize);
                }
                audioTrack.release();

我测试了不同采样率的样本，范围从 19250hz 到 44100hz 。对于所有情况 K900 强文字播放不稳定而Oneplus播放顺畅。我不认为 K900 不足以完成这项简单的工作。 请帮助。

修改 这是我打算使用的代码：

              try {
                //dataInputStream = new DataInputStream(socket.getInputStream());
                //response = dataInputStream.readUTF();
                int bufferSize = AudioTrack.getMinBufferSize(SAMPLE_RATE, AudioFormat.CHANNEL_OUT_MONO,
                        AudioFormat.ENCODING_PCM_8BIT);

                if (bufferSize == AudioTrack.ERROR || bufferSize == AudioTrack.ERROR_BAD_VALUE) {
                    bufferSize = SAMPLE_RATE * 2;
                }

                int readBytes;
                byte[] buffer = new byte[bufferSize];
                bufferSize = bufferSize * 2;
                AudioTrack audioTrack = new AudioTrack(
                        AudioManager.STREAM_MUSIC,
                        SAMPLE_RATE,
                        AudioFormat.CHANNEL_OUT_STEREO,
                        AudioFormat.ENCODING_PCM_8BIT,
                        bufferSize,
                        AudioTrack.MODE_STREAM);
                audioTrack.play();
                DataInputStream in = new DataInputStream(socket.getInputStream());
                while (true) {
                    try {
                        if (in.available() > 0) {
                            readBytes = in.read(buffer, 0, buffer.length);
                            audioTrack.write(buffer, 0, readBytes);
                        }
                    } catch (SocketTimeoutException s) {
                        System.out.println("Socket timed out!");
                        audioTrack.release();
                        in.close();
                        socket.close();
                        break;
                    } catch (IOException e) {
                        e.printStackTrace();
                        audioTrack.release();
                        in.close();
                        socket.close();
                        break;
                    }
                }

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
