When someone who knows how to edit audio files takes the time to actually build them.

Modeling the Reading Railroad in the 1950's

I am becoming more and more convinced that the sound, or more specifically the quality of the sound, produced by any model locomotive decoder is truly in the ears of the beholder. The model in the link sounds like a jet revving for takeoff to me. I think it has something to do with the lack of bass reproduction.
There was another link on the screen when I listened to the original. http://www.youtube.com/watch?v=P_Nsrq5WnO8&feature=related
This is what I'd like to hear from the model.
See that's just the startup though. The model one, those sounds were recorded by tthe builder from an actual SD40-2, and that sounds pretty much liek what I hear when one goes by anywhere it's actually working (ie not coasting downgrade). If anything's weak in his mix, it's the horns being quieter than the prime mover. I like the way he made the turbo fade on each notch, although that's probably as much the real thing as it is any fancy sound editing.
In fact ehre, check out another relatedone with a turbo-645, even at IDLE all you hear is the high pitch of the turbo whining. http://www.youtube.com/watch?v=BBZQox-N7lI&feature=related. Or this one, although there's way too much wind noise. Listen when they throttle up - screeeeeeeeeeeeeeeeeam then settles down but that turbo is always there http://www.youtube.com/watch?v=WwaOHRKItQE&feature=related
Even better this one - doing basically what the model was doing. http://www.youtube.com/watch?v=EqzSJOnW9-c&feature=related

Yes, this one is close. But there still is a pronounced bass rumble that I'm not hearing from the model. I think it must be a speaker thing. Or maybe it's just my hearing.
