Another thought that might apply to you since you understand frequencies and I do not. I bought my rescue dog soothing music in this tiny cube. He definately calms to the music. (he was very abused). I love the cube but hate that it is only one device of one recorded sounds. What I do like about it is it is not connected to the internet has no camera no recorder so its not intrusive. I would love 7 boxes like this in each frequency for humans. That way one could change frequencies for meditaiton or sleep without worry that the music is compromised. I hope that "sings"to your abilities. If you make a million $$ on the idea dont forget me lol
