The core of the problem appears to be that there is only one sound-device
on a typical system, and the mixer settings are a property of that one device,
not per-process.

If the VoIP application obviously specifically requires to record only the
microphone (in order to transmit it to the parties), then another process
cannot have its own settings to record everything.

I'm not sure if you need a recording solution for yourself, or if you 
intended to create a transcription add-on to be used by Joe "VoIP" User.
If it was the latter, then I fear it won't be that easy.  If you create
your own VoIP client that would be a different story, and also if there
was an existing VoIP client with a decent API for plugging into the sound
stream.
