Audio recording

[MarcAnt01]

Are you considering the possibility to record audio along with the video? Is that allowed by the APIs you use

This sample is primarily about using the Windows.Graphics.Capture and Windows.Media.Transcoding APIs. Windows.Graphics.Capture only has the ability to capture graphical content. Windows.Media.Transcoding has the ability to add-in an audio stream, I believe, but you need to get the audio from somewhere else first.

There are two ways you can go about this:

• Some systems have a synthetic loopback audio device that can be used as a micrphone in the AudioGraph API. This is less consistent, mainly because not all systems are guaranteed to have this synthetic device. For example, my system has a device called "What U Hear" and it comes from my Sound Blaster audio device integrated into my motherboard.
• Use WASAPI to record loopback audio. It's a C++ API, but you may be able to find some C# bindings somewhere. This is probably the more robust option.

This project may in the future explore audio recording, but it isn't an immediate goal that I have.

Thanks a lot for the detailed explanation
