Introducing the XNA Game Studio 4.0 Refresh Microphone API

The XNA Game Studio 4.0 Refresh Microphone API has the following functionality:

  • Captures the audio stream from a microphone or a headset.
  • Provides microphone enumeration.
  • Submits and controls a stream of audio buffers for playback using the DynamicSoundEffectInstance object.
  • Plays back audio through a headset.
  • Provides a cross-platform API for Windows and Windows Phone.

Microphone API Process Workflow

The Microphone API behaves like a simple audio recorder with a configurable capture buffer. It has been designed with the following development process workflow:

  1. Select the microphone connected to the device.
  2. Configure the microphone's capture buffer size.
  3. Control the recording using standard transport controls (Start and Stop).
  4. Retrieve the captured audio using the GetData method.

Also, you can use the BufferReady event handler if you want to be notified when the audio capture buffer is ready to be processed.
