Thanks tomas and Hypnodude,
I was curious about that myself. I’ve also read that about MP3 compression, how it takes away sounds not heard by the human ear. I was wondering if this had an effect on hemi-sync. I was actually thinking of posting this question.
but Hypnodude is right. The hemisync effect is still produced. The wavering sound you hear in hemisync is created by your brain. If you turn the balance on your MP3 player left, you only hear 1 consistent tone and the same for the right. But when you put both together your brain starts to produce the “wavering” effect, which is what makes hemisync. My experience so far has been very rewarding. This is my second time trying hemi-sync and this time seems more successful.
