If it's data that is "k-rate" data (that is, non-real time information like meter values or whatever), then your best bet is to publish it through the IORegistry and write a HAL plug-in for your device that provides the information as a custom property.

Of course, the app in question has to know about the custom property and what to do with it. There is no way for a driver to "push" things at an application.

What is the recommended way to get information (very low bandwidth, that's derived from the audio stream) from my own Audio Device driver to a user space application?

I can get the info I need by sampling my data, but need to "forward" over to a user app.
