Sallen Key Low Pass Filter, bandpass filter

so I think I read we hear logarithmically too are these frequencies feasible shown below, these are for the different columns
- 45 Hz
- 64 Hz
- 91 Hz
- 128 Hz
- 181 Hz
- 256 Hz
- 362 Hz
- 512 Hz
- 724 Hz
- 1024 Hz
- 1448 Hz
- 2048 Hz
- 2896 Hz
- 4096 Hz
- 5792 Hz
- 8192 Hz
- 11585 Hz
- 16384 Hz (16 kHz)
- is this correct and it means that the bass frequencies are further apart at the bass levels and tighter at the high pitch tones, or the other way around where the bassy frequencies are closer together and the the high frequencies are further apart
what I am struggling with is how to space the frequencies
like evenly spaced between 45Hz and 16kHz
or do you choose them logarithmically spaced
for a tone that, nevermind did a quich search and answered my own question!
cheers!!

Waiting for parts now, it's so nice of you all to spend your time (that I assume is valuable) to help where you can, nice good bunch of lads. I now feel quite comfortable here and you all have upmost respect and I try and do the same. This forum and extended to the members are and is, such a valuable resource and I have learned a great deal since being here thank you for being supportive and welcoming god bless and cheers, Scott
Ok so I know I've been pointed here to make the pre-amplifyer https://www.epanorama.net/circuits/micamp.html
but I would like to know if I can buy one in chip form for electret microphone because I want as minimal noise as possible. I am able to make the circuit suggested and have the parts too, but from what I read it's a bit noisy, can that be negligable or will one ready made in a dip type package be much better as in their effects in perfomance, cheers

Hello,
Have a look at fig 8 of the following page:
sound-au.com
It shows the connections on the mic.

Have a look at fig 8 of the following page:
Recording and Measurement Microphones
ESP Audio Projects - Measurement and recording microphones, using inexpensive electret capsules for outstanding performance
Bertus
so this will plug right into the electret mic pre-amp yes?
