I have relatively simple needs. All I want is to be able to measure the response of a room/speakers to impulses and sine-sweeps. I have measuring microphones, just no appropriate software.
I was on a course a few months ago, where the lecturer did some measurements, and I'm sure he said the software he was using was free - but no amount of googling seems to be turning up anything.
Anyone know any? Or an easy way to set up/calibrate SoundForge to do the same job?
