Let’s say I have a sample sampled at C-4. I play melodies with the white keys only, so CDEFGAB.
I would like to find out a way of mathematically going: “OK, these are the frequencies for each octave of CDEFGAB” - and boosting those frequencies with an EQ plugin (EQ8? FabFilter Pro-Q?). Or: alternatively, kill the frequencies that are C# D# F# G# A#.
How would I go about doing this kind of “cleaning up” frequencies of a sample?
I’m thinking “select the contents of a channel, press a key -> EQ8/Pro-Q boosts the frequencies I play at, and kills the frequencies I’m not playing at”.
What you essentially will be doing is to boost/attenuate the fundamental frequency of the sound.
I’ve experimented with notch filtering out all non-diatonic frequencies of a song. It did bring some kind of flavour, perhaps even subtle increase of clarity, but I’m not sure if it’s technically recommended. Filters will add phase shifting, and I theorize that non-diatonic overtones gives a sound some amplitude at spots that are less likely to clash with other notes/instruments.
Hi. I’m new but I did come up with a basic system of calculating note frequencies with a 99.20% or greater accuracy using third grade math. For comparison, it’s usually more accurate than manually sweeping bands in a GUI. It’s called the F350 Method and you can see it here:
