Attached should be the version I did. I could do it again with better headphones if need be, but I have no idea if the one I just did is out of whack or normal or what!
Stumbled across that one before...
One thing I noticed: You've got to use headphones for this!
Other then that I found almost impossible to tell if tones of 250Hz or below are quieter or louder the the 1k. No problem to tell if they are louder then the frq. next to it but not the 1kHz. Also I am overly sensitive to 8kHz, had to drop that by 6dB compared to the 1k. But I knew that beforehand...
