Answer 1

You can use the APIs in the Windows.Media.Audio namespace to create audio graphs for audio routing, mixing, and processing scenarios. For how to create audio graphs please reference this article.

An audio graph is a set of interconnected audio nodes. The audio file you want to record supply the "audio input nodes", and "audio output nodes" are the destination for audio processed by the graph, audio can be routed out of the graph to the target audio files. In the "MeeDJ" windows store app, it can mix two audio and record it into one. In this situation we can use "submix nodes" which take audio from one or more nodes and combine them into a single output .

And for starting and stopping recording we can try to use Starting and stopping audio graph nodes to implement. You can also try to Adding audio effects as the "MeeDJ" did.
