With regard to the letter in the January issue from the fellow looking for test equipment for measuring loudspeakers (“When I Grow Up, I Want to Be Mark Peterson”): A good, reasonably priced, semi-professional means of measuring loudspeaker capabilities can be found using the software package Arta (artalabs.hr). I have been using this software for well over a year, and it provides most of the primary loudspeaker characteristics. The FAQ at their website recommends the necessary hardware to purchase to support one’s measurement needs.

Thanks for the recommendation, Keith. In our previous response, our own Tom Norton recommended the $300 OmniMic V2 system from Parts Express as an affordable and all-inclusive option (mic and software included, just add PC). I’m not familiar with Arta, but I can see from the website that the cost for unlocking this “shareware” for an individual user is just 79 euros (about $96) and that you would presumably just add a computer with one of the compatible soundcards and a calibrated mic.—rs
