回答1:

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 :

you initialize a buffer with the size of the data :

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

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   
    }

you'll need to include and everything is stated in the tutorial in Details

using Microsoft.Xna.Framework.Audio;
