Ok... I have been over thinking rock n' roll lately.
What I am thinking is....
If it takes roughly 28 feet for a 40hz wave form to develop
does that mean that that is the optimal distance for micing that frequency?
I figure only about 440hz and higher develop fully within 4 feet of the kick
drum.
So if i remember correctly a 60hz frequency will go thru one cylce at approximately
20-30ms into the kick sound.
So I was wondering if shifting the lower frequencies back towards the beginning
of kick beat by approximately 20-30ms if that would give a more powerful
kick sound/tone.
Make sense?
Anyway I will be trying it.
Wonder if the same will help bass guitar or any instrument.
Perhaps I ned to just go to sleep.

Don't forget to think about proximity effect in this equation. I do
encourage you to do experiments, keep going man. What you'll learn about
your mics, instruments and rooms will stay with you long after any recording
medium. Acoustic knowledge never goes out of style.

i have my room mics set about 3.6' in in front of the kit and 4' off
the floor using M/S encoding. the overheads are 5' off the floor, 6'
apart and 4' back from the drummer. for a different vibe the room
mics can be placed up to 15' away from the kit and the file is shifted
to approximately the same time as the overheads to reduce some of the
delay which mostly affects the kicks clarity.
