Room impulse?

[horizonsofchaos]

how do i take an impulse of my room to find out what frequencies drop out.

i gave seen people on here post pictures of theirs, and am wondering what programs i need / how you do it.

You would need a sine wave generator and an omni microphone (ideally) with the flattest frequency response possible. You would run this sine wave generator through your monitors and place the microphone at your listening point, while recording the signal sweeping from 20hz to 20khz. There are programs made for this (I am not too well versed in this method). You will use a spectrum analyzer to find out what frequencies are either boosted or attenuated so you will know how to treat them.
