CLM Siren Slideshow & Synth (Attack & Alert)

The CLM Siren is a very mysterious air raid siren indeed. No one knows of its exact sound for certain. It is believed (and I believe so too) to sound much like the famous Minor-third sounding 3t22 but with a VERY dominant high pitch from the 12 Port sound of the siren. This is because there are only four stator holes for the 10 port part of the siren. For the most part, the CLM can appear to sound single tone from a distance but getting closer would let you hear the hint of dual tone. Pictures are NOT mine, but belong to their respectful owner's.
