Hi all, I played the 3 different versions with the wrong note on my computer and here are the results: The highest version was too high (or something else perhaps?) for the external speakers on my computer. These are speakers anyone can purchase for under $50, two tweeters and a subwoofer, and sound fine for most things. The pitches went in and out. On my headphones I could hear the pitches. The other two samples were audible on the speakers. John and Bob, i think your points are well taken. The original Mahler 1 wav file plays on my speakers. I'm not sure what i am hearing in terms of overtones or folding, but i can tell what the pitches are.
