Version 1.3 …

I had to revert to the old noise-generators. Your noise-code was more elegant but it wasn’t producing the same radio-like hiss & crackle sounds. “clip2”, (effectively normalizing to 0dB before clipping), also had to go : it was making the very clipped sounds deafeningly loud.
HelmetRadio 1.3 , like previous versions only produces (optional) constant hiss & crackle on the left channel, so OK for mono , not stereo . (Oddly the radio-crackle, which only occurs with speech, is on both channels).
Add enclosed telephone-booths to that list.
