Room EQ Wizard is a cross‑platform app designed for measuring the response of your speakers and room but, coupled with a decent audio interface, there’s no reason you couldn’t use it to measure the performance of mixers, preamps or audio processors.
I’m about to be given an old mixer to play with in my studio and am planning to check each input and output, check the EQ does what it’s supposed to, etc. But I’ve realised that it might be even more fun (I’m weird!) to measure the noise, distortion, and maybe other things about each channel, insert, group and so forth. Would Room EQ Wizard be a good tool for this? Would it be easier or better to borrow an analyser such as Audio Precision? I don’t mind if the mixer is a bit crap here and there, as it’s free and I don’t really mind noise, aesthetically, but it’d be nice to know!

SOS Technical Editor Hugh Robjohns replies: Although Room EQ Wizard is geared towards acoustic measurements, it could be used to test audio equipment too. In fact, there are countless other software audio analysis and measurement tools available, including a suite from Audio Precision. Obviously, the measurements will be limited by the capabilities of your audio interface, but that shouldn’t impose too much restriction on assessing the performance of an analogue mixer.
