Hey punks I was recently mixing at a gig where the acoustic guitar was taking off somewhere in the lower-mid frequencies. I knew that he was tuned to drop 'd' and knew that it was the low 'd' that was creating the feedback but I couldn't recall the actual measurement of low 'd' in hertz. So I had to play the guessing game and sweep all of the the mid-low frequencies during the performance.
I knew that there was a relationship between the differences of each semitone in regards to its hertz. Ie. A=440, G#=415.3
So I came up with the percentage in a number which I have memorised for the next time I need to convert notes to hertz.

Basically for the semitone down, you multiply the original hertz by 0.943875  Ie. 440 (A) x .943875 = 415.3 (G#)

I know there is a complete formula of how they do this but i find a number a lot easier to deal with on the go. ;D

I just find it heaps easier than memorising every frequency in the western scale

Hmmm...it sounds like a handy theory antonio but it's a bit of a handful to remember. I may have to write this one down. Once I memorise it though I can see myself using it at gigs when I do sound! 8) Its a very nerdy approach but I expect that I will eventually help me memorise the actual frequencies in the end.
Thanks  :clap:

This does seem to work for a quick approximation! Good work!
