Did a great job of measuring and graphing frequency response with no complications or other equipment. Glad I spent $30 on this.

Just quirky and buggy

I can get measurements with this, with a mic and interface or without. 3 starsI purchased the filter designer for 10, and its not effective. It won’t stay licensed, constantly having to reauthorize the purchase. It forgets my pref settings…. Worthless really.The 3d graphic is terribly twitchy, hard to manipulate to make observations.I’ve deleted and reinstalled, but the application just seems as though it is a wuirky, buggy thing.All in all, not sure this is the greatest option.
