DIY Audio Analyzer: Every DIY audio enthusiast dreams of one day owning an Audio Precision or Rohde & Schwarz audio analyzer. But only very few can afford such an instrument. I decided to build one myself around a Behringer UMC202HD Audio Interface, a Home Theater PC and self-made front-end electronics. At the time of writing (December 2021), I’m still working on it, but I will already share the parts I’ve finished, so you can get a sneak preview of what is to come.
