EQ Setting Questions.

[mulletdude]

Ok i didnt know where else to put this question but i was wondering if anyone knew of a software for free that will do as follows.
-Take a measurement from a microphone.
-Suggest EQ for the room using a 31 band stereo EQ.
-Be able to use multiple measurements before doing above.
-also like i said earlier it HAS to be free.
I want to use this software to set up my EQ for dances and events like that as I now own a DJ company but i dont have tons of money.

Any of the free measurement software packages out there will let you measure response. You'll have to use your brain to figure out where eq would be useful, but that's pretty easy. Averaging curves is a bit trickier... You could do it yourself in excel, for example, with any software where you could export curves. However that will definitely slow you down.

I'm curious. Why exactly would you wish to do this?

(most) People that will be listening won't particularly care how it sounds, so I think you'd be throwing money at a non-existant problem. Sure, there's always one or two that say "oh - that could sound better", but 1 or 2 in a crowd of 100 isn't anything to worry about.

If you take an on-axis measurement with a mic and EQ it to be flat (or not flat in the case of a dance event), it will only be so on the measurement axis...move your head a few inches to the left and the response is changed...Best solution is to EQ by ear, play some music and walk around the room to see how it sounds in different locations.

I have seen some large venues will play noise through the speakers with mics placed around the room and a spectrum analysis of each mic...then move speakers around to find the optimum location...but this is quite an expensive procedure.
