Are they bullshit or what? I have been looking for scholarly papers and anything repeatable. If I can trigger the placebo effect it looks like I should be buying some crystals to go with my monitor.
Do you have experience with specific recordings that aren't placebo? Can you please share links to those? I would be interested in listening to them, thanks!
Different offset frequencies have different effects so you should do more research and maybe experiment with some different beats before you just put one on repeat.
Some beats made me sleepy others made me agitated. You're probably looking for something to make you focused.
