Has anyone set up TrueRTA? Was wondering how accurate it is, hard is it to calibrate, set up and use, what soundcard do you use, etc.?
Setup is trivial. Any mic/sound card will work but a USB mic makes it simple.Has anyone set up TrueRTA? Was wondering how accurate it is, hard is it to calibrate, set up and use, what soundcard do you use, etc.?

Thanks, I was thinking of using it in conjunction with the AS cartridge alignment LP.
I have used true RTA for almost 10 years now.It kept me sane and played a huge role while I was designing and building( well having it built ) my speaker system. I mainly use REW now for room/speaker measurements but true RTA can still do stuff that REW can't and vice versa.It has eg a facility for holding peaks so is valuable for measuring tape recorder FR with a test tape sweep or phono system FR with an appropriate test record sweep.I am not totally comfortable with the oscilloscope function though but that probably is more due to my computer illiteracy than the program. I also never quite figured how to take snapshots of measurements but again that's me as freddyi over on AA High Eff often posts nice true RTA snapshots. The people at true RTA is also very helpful and that $39 gets you a code that can be transferred from computer to computer for ever.
It is as accurate as your souncard/interface is.Again probably my Neanderthal outlook on life but a calibrated USB mike recently led me straight into Alice's maze as recalibration of my speaker output had me listening to a + 20db bass boost for several weeks,rattling the house apart , making the dogs vomit and causing panic attacks in my kids and all passers by whilst I bravely soldiered on convinced that it measures flat so it must be right. Return to my trusty Focusrite interface and yet another calibrated mike showed my USB mike measurements to be way off and my ancient trusty Behringer to be correct after all!
