Micro-Tuning: Matching Up the Fine Pitch ratios with hZ...?

Started by sivante

So, I've been curious about integrating binaural-beats type frequencies into my productions, and curious as to the details of how the micro-tuning works…

From what I've researched, the trick is to pan two separate tones left/right that are the distance apart equating to the frequency you want to "induce" - i.e. if wanting to trigger a delta brainwave at 3hZ, send a 440hZ to one side and 443hZ to the other…

Question:

What do the numbers for the fine-pitch settings translate to in hZ?

I do know that it is commonly suggested that if desiring to detune instruments from 440hZ to 432hZ, that works out to -0.32 cents. However, I don't imagine that'd work out to an equal 4 cents per hertz across the board - as those ratios may vary depending on whether going higher or lower in frequency.

Might anyone have any experience doing this and know, and/or have links to any resources such as charts that map out exactly how many cents you'd need to shift to create those differentials through the spectrum?
