Re: [mediacapture-main] Specification to capture unmodified audio

@alvestrand, I guess it depends on how you define processing but beyond all the existing filters (below) which actively process the raw audio (by default in most cases), there is also the case of the analyzer node which is attached to the audio stream to perform FFT processing. So I am not sure what you mean when you say the spec does not allow any processing. What kind of processing are you referring to specifically? 

Sample rate should be at the HW processing layer but could be in a firmware core layer if HW can't do it and Windowing of the raw audio is certainly less complicated than most any of the existing filters and certainly FFT. But I would be happy if the default mic stream was simply a raw sample at the two most common sample rates of 44.1KHz and 48 KHz.
