如何实现音频呼吁在Android的插座

本文介绍了如何实现音频呼吁在Android的插座的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经搜查，发现声音流或音频通话的code简单的插座两款Android手机之间。我已经实现这一点，但是这code不工作。我无法听到任何声音。

I have searched and found a code of voice streaming or audio calling between two android phones on simple sockets. I have implemented this , but this code is not working. I am unable to hear any voice.

接收器code：

private int sampleRate = 44100; private int channelConfig = AudioFormat.CHANNEL_CONFIGURATION_MONO; private int audioFormat = AudioFormat.ENCODING_PCM_16BIT; int minBufSize = AudioRecord.getMinBufferSize(sampleRate, channelConfig, audioFormat); public void startReceiving() { Thread receiveThread = new Thread (new Runnable() { @Override public void run() { try { DatagramSocket socket = new DatagramSocket(50005); Log.d("VR", "Socket Created"); byte[] buffer = new byte[256]; speaker = new AudioTrack(AudioManager.STREAM_MUSIC,sampleRate,channelConfig,audioFormat,minBufSize,AudioTrack.MODE_STREAM); while(status == true) { try { DatagramPacket packet = new DatagramPacket(buffer,buffer.length); socket.receive(packet); Log.d("VR", "Packet Received"); //reading content from packet buffer=packet.getData(); Log.d("VR", "Packet data read into buffer"); //sending data to the Audiotrack obj i.e. speaker speaker.write(buffer, 0, minBufSize); Log.d("VR", String.valueOf(buffer)); speaker.play(); } catch(IOException e) { Log.e("VR","IOException"); } } } catch (SocketException e) { Log.e("VR", "SocketException"); } } }); receiveThread.start(); }

发件人code：

Sender Code:

public void startStreaming() { Thread streamThread = new Thread(new Runnable() { @Override public void run() { try { DatagramSocket socket = new DatagramSocket(); Log.d("VS", "Socket Created"); byte[] buffer = new byte[minBufSize]; Log.d("VS","Buffer created of size " + minBufSize); DatagramPacket packet; final InetAddress destination = InetAddress.getByName("192.168.0.216"); Log.d("VS", "Address retrieved"); recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,sampleRate,channelConfig,audioFormat,minBufSize*10); Log.d("VS", "Recorder initialized"); recorder.startRecording(); while(status == true) { //reading data from MIC into buffer minBufSize = recorder.read(buffer, 0, buffer.length); //putting buffer in the packet packet = new DatagramPacket (buffer,buffer.length,destination,port); socket.send(packet); } } catch(UnknownHostException e) { Log.e("VS", "UnknownHostException"); } catch (IOException e) { e.printStackTrace(); Log.e("VS", "IOException"); } } }); streamThread.start(); }

我调试的code和包被成功地发送和 speaker.play（）也被称为。但没有语音

我已经实现在一个单一的应用程序和活动这code。有两个按钮开始听和开始流式传输

I have implemented this code in a single application and activity. With two Buttons Start Listening and Start Streaming

推荐答案

getMinBufferSize（）可能不是同一个 AudioRecord 和 AudioTrack （了解到硬盘的方式）。请确保您使用的是两个大。

getMinBufferSize() may not be the same for AudioRecord and AudioTrack (learned that the hard way). Make sure you are using the larger of the two.
