Hi everybody,
Does it make sense to solder a RC-filter between the microphone and MICIn (AudioAdaptorBoard)?
The idea is to lowpass all frequency less than ca. 350Hz, to give Teensy an as clean as possible sound to process. (Everything over ca. 400Hz is unused and should not disturb.)
Or is it obsolete because everything can made in code like demonstrated in my last post?

I have already tried to add a RC-filter but it didn`t work. There are surely some influences with the already soldered components on AudioAdaptorBoard?!.
Can anyone give some help how to connect the AudioAdaptorBoard-MicIn with a RC-low pass filter and the microphone?
