im not sure if this has been mentioned, but i will anyway, just 2 important frequencies for you to know and understand
85hz and 2500hz
the reason being,
around 85hz= the frequency your chest cavity resonates at.
around 2500hz= the frequency your ear canal resonates at.
so why is this useful to know?
well, if you play want your tune played in a large environment, such as a club, with a large sound system, you can EQ your bass to give the 85h area a little boost, while this is barely audible, you would certainly feel it in a club situation, you know how those times youve felt your insides turning from bass? thats 85hz.
so what about 2.5khz, you know if you have a hat/cymbal, or other high frequency sound that seems so much higher in the mix than it appears it should be from the level its generating?
thats because your ears are hyper sensetive to 2.5khz, its dangerous, in fact, nearly every single speaker made is dipped in this area for that very reason, it could deafen you.
you know that try using a pure sine wave, play it from 0hz up to 20khz slowly, youll notice it gets louder and louder as you get closer to 2.5khz. and then quieter again, as this is the frequency your ears are most sensetive to.
so if your hats are too loud, try applying a dip at around 2.5khz, rather than dropping the whole level, youll find it gives your track a little more ease of listening.
