Speaker measurement software?
« on: February 16, 2014, 03:03:29 AM »
Hopefully I put this in the right area of the forum.

I was wondering what software Purrin and Ultrabike and others used to measure headphones, and if it would be any good for measuring speakers.
I just bought a Dayton Audio iMM-6 microphone that's supposedly made for smartphones and whatnot, and I was thinking I would either hook it up to my iPad, Android phone, or Windows 8.1 tablet's TRRS jack and try and take some measurements of my speakers and play around with positioning and maybe Windows systemwide EQ.
Does anyone have any suggestions for a decent free measurement software either on mobile platforms or for PCs?
Thanks.

Room Equalization Wizard is what you want. Very powerful free software that's actually meant for measuring loudspeakers and rooms first. Register on HomeTheaterShack and you can download it. I don't think it'll run on your mobile though.

You can also try ARTA (http://www.artalabs.hr/) which isn't as hand-holdy, but similarly useful for the other types test signals it can generate.

I think coupled correctly, the iMM6 might actually be useful for measuring IEMs and the like as well, just that it will take some work, one of my friends was recommended that route by a established IEM designer.

REW is powerful and more than enough for most measurements though.

Thanks guys for the recommendations! Is it possible in REW to export settings from one computer and use them on a different computer?

And firev1, how hard would it be to make an IEM coupler? That sounds quite interesting!

What my friend did was to couple the IEM to some acoustic tubing directly into the mic,  I'm not really sure how has the setup changed or evolved ever since. For the mic, he is using a wm-61 capsule with Linkwitz mod applied. The setup is ridiculously cheap and is mounted into an aluminum piping. I'm personally considering a calibrated mic.

I have a few of those WM-61 capsules on hand myself. Been planning on building some sort of improved headphone coupler, but an IEM coupler might be fun too.

Could you explain exactly what you mean by acoustic tubing? I looked online and all I found was stuff like this: http://www.amazon.com/HDE-Acoustic-Earpiece-Compatible-Motorola/dp/B00838DCCO
which I am assuming would not be very ideal for measuring stuff, assuming I could even put some of that around the microphone...
