Demonstrates how to do various audio related tasks using the Windows Audio Session API (WASAPI).
Specifically, this sample covers:
- Enumerating audio playback devices attached to the system and retrieve additional properties.
- Demonstrates how to opt-in to hardware audio offload on supported devices.
- Demonstrates how to implement the basic media transport controls in order to properly support background audio playback.
- Playback of audio using the Windows Audio Session APIs.
- Capture of PCM audio using the Windows Audio Session APIs.
- Low latency audio playback and capture.
For more information on adding audio to your Windows Store app, see Quickstart: adding audio to an app.
Playing audio in the background is supported by the Windows Audio Session API only in communication scenarios as demonstrated by the VoIP sample. Instead, for general background audio playback of media, use the BackgroundMediaPlayer class demonstrated in the Background Audio sample.
