At-home En­gi­neer­ing

Sound & Vision - - LETTERS -

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 (ar­ta­l­ 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
