Apparently I have unknowingly had my computer audio set to mono for maybe 2 or so years. I feel like an idiot. Now I am going to go through the gateway hemisync wave 1 tapes again to see if I can succeed this time. 
Thankfully I have only been using them infrequently for about the past month, so I didn't lose too much time or progress (and some of the exercises had worked for me in mono).
I honestly have no idea how I hadn't noticed despite using this computer everyday during that time period...

I think that's okay. You still gained from your experrience. But it's optimal to use the best set-up. Still, I don't thnk you wasted time on your tries. If you did the process, that's success in itself. Keep going with the knowledge of how to have an optimal experience.

I agree it wasn't wasted time, but it was a silly mistake on my part especially where I had never noticed over a period of years.

Fine. Now you know. Continue on your journey, anon. I deeply desire for all of us to make it in the end.
