AudioStreaming通过套接字在android

我想通过Android上的套接字音频流。我使用AudioRecord获取客户端录制的音频和AudioTrack类以在服务器端播放原始数据。但我无法做到。有没有其他的程序可以做到这一点？AudioStreaming通过套接字在android

你无法发送的数据？或者无法在接收端正确播放？与MediaRecorder类一样，AudioRecorder类可能会为标题留下一些空间，然后在录制完成后执行查找以填充标题。由于无法在套接字上查找，因此标头将写入文件的头部。我认为你最好的行动方式是将文件写入SD卡，然后使用hexeditor将字节与正在工作的音频文件进行比较。然后，您应该能够确定标题的格式，并且在收到标题时可以查找文件的开头（或缓冲区的开始）并将标题写入适当的位置。
