Mathematical mixing

Member Since: Feb 18, 2004

I found some interesting formula in russian forums. It looks so:
Fy= b * ((a/b)^((2*y-1)/2x))
here we have,
a - highest frequency, (egz 16000Hz),
b - lowest frequency (60Hz),
x - number of instruments in the mix,
y - index of instrument in the mix scale.

It is allowed to give several frequencies for every instrument (not more than 3).
So I can put instruments in order: bass, kick, snare, synth, hihat... and then attribute calculated frequencies to them. Have you seen this approach? Maybe it is new only for me. I tried this:

and got
F1 - 55,8 ;
F2 - 193 ;
F3 - 670 ;
F4 - 2324 ;
F5 - 8057 ;
looks quite logical sequence

Quite new to me, although it should not be supprising I guess. I've ran across a ton of equasions describing micing techniques. Personaly I can't preceive it's value in practical terms, but then I know nothing of it, so my opinion and a buck and a half will get you a cup of coffee. Might be usefull in "making room" within a mix. If you feel like it maybe you can further define the scripting e.g. Fsuby is Frequency of the whatsit whoosit number six!

I never poo poo something without trying it, or at least try not to.

Lost for words with all to say.

I sort of like that. It gives you a perspective of what the spectrum will look like with your instruments through a formula. I would like to see more examples. I'll try to do one tonight and see.

Walt, your mailbox is full, so I can't PM you 'bout this weekend . Sorry about the thread-jack Edvo... good stuff, I think .

coffee IS good. black.

i sort of get this, but i dont understand what y is, and i dont see the resultant 3 freqs, just one for each instrument. it looks like this formula gives you a center frequency to accentuate in your mix for each instrument?

My english is not developed well, so I did not understand the idea about coffe. And what corcerns y, if you have 5 instrumets in the mix, and you want to give 3 frequencies for every instrument, then you will have x=5*3=15. And y is the index for every frequency. You calculate the F1, F2, F3...F15, and looking to the values of Fy you decide that you want to assign F1, F5 and F11 for kick, F2, F9, F13 for bass and so on. Whis is how I understand it. I defined x not correctly above, it is not the number of instruments, but the number of frequencies in the frequency scale. I never tried this mathematics, and I am not sure if I will have patience to try, but the guys wrote that they use it.

Sorry Edvo, from your writing your english seems fine.

It is a silly joke. Kind of a math joke. If a cup of coffee costs $1.50 US and you can buy a cup of coffee with $1.50 + my opinion, obviously my opinion is not worth much.

That's interesting.... but I think I'll just let my ears do the math.
