推荐答案

不确定您是否熟悉WP7中的麦克风通话 但您可以查看博客帖子以获得完整的详细教程:

not sure if you are familiar with Dealing with micrphone in WP7 or not but you can check this blog post for a full detailed tutorial :

您使用数据大小初始化缓冲区:

you initialize a buffer with the size of the data :

_buffer = new byte[_microphone.GetSampleSizeInBytes(_microphone.BufferDuration)];

，只要此事件处理程序中的麦克风数据准备就绪，就可以从麦克风获取数据并将其添加到缓冲区中，然后您就可以使用它进行任何操作:

and whenever the Microphone data is ready in this event handler get the data from the microphone add it to the Buffer then you can do anything using it :

  private void MicrophoneBufferReady(object sender, EventArgs e)
    {
        _microphone.GetData(_buffer);
        //Do something with the data   
    }
