I'm interested in finding out which frequencies are emphasized or attenuated in the room where I listen to playback and try to mix. I know there exist proprietary solutions for some monitoring systems which can do this - they do it by placing a microphone in the room and running various sounds through the speakers, and measuring the output. Based on the results, it's possible to create an EQ curve that matches your room.
I don't have any such system. I have a set of generic microphones and a pair of ordinary monitor speakers.
Does there exist any software packages that can perform this kind of correction on a generic system like this?
