Sure. In the first group of three:
50hz unaltered, theoretically "perfect"
20hz 6dB/octave high pass
20KHz 48dB/octave low pass with 7KHz Q=.5, gain=3dB filter.
Graph 4 is phase shift, -90@20hz, +90@20Khz, linear.
I'm fairly sure I never claimed these to be actual headphones. They are all filters.
They all sound nearly identical with a 50Hz square wave, and absolutely identical with music. Even the rather nasty looking fourth one.
If you gotta have proof, suggest some audition material and I'll see what I can do. Or better yet, build these yourself in a DAW. I used Audition. That way I'm out of the picture as a "liar".
Guys, it's been a slice, but I got to bail on this one now. I think most readers got my point, and all I've done with scuttle is make him mad. And I'm fairly sure he'll be mad anyway.
