Unity Recorder

I have the following situation:

I am recording facial mocap animations via the unity recorder(2.5) and want to record microphone input at the same time via a custom script.

Being lazy as hell I would like to get the file path string defined in the unity recorder window to serve as the file path for my audio recorder and if possible trigger audio recording when triggering anim recording.

Is there a way to call the Unity recorder to start recording via script?
