Hang on, is this just recording a DC value with the ADC and then looking at that?
The RMS of the Mic signal is taken and compared to the trigger level set. If it's above that level then an IRQ is raised.
What I'm trying to figure out here is if this depends on the audio routing at runtime or if it's got dedicated configuration?
This feature is available for any/all mics connected. Which mics are enabled is a runtime configuration of routing, so to me it makes sense also that we can configure which channel triggers an event, based on our scenario at that time.
