Amazing – SPL Review

Oh no! A disastrous update!!! They finally took the horrible, battery-draining background operation so-call "feature" out of RTA, but they put it into SPL. Now, when you exit this app in the conventional way, it keeps running and draining your battery!!! Why they think this is a good idea or should be the default operation is just beyond me. Please, please, make this behavior optional and default it to operate in the way that most iPhone apps do, to exit the app when you press the home button. ------ original review ------- I have recently had the opportunity to compare with a very calibrated instrument and was very favorably impressed. This thing works very well. I also checked my Radio Shack meter at the same time and it's good right around 1KHz which is where -- if you read its instructions -- it is calibrated. The Radio Shack SPL meter, by the way, while a bargain for the price and quite good for what it is, is not a good tool for tuning subwoofers at all. This iPhone ap, while better, still isn't the best for subs either with the built-in mic, but worked much better with an external. Also, this ap's A-weight filter is better than Radio Shack's. In conclusion, this ap is a bargain for the price and so handy to have with you. A+. My one suggested improvement: a logging mode which logs SPL at selectable intervals -- minutes and seconds -- and then can e-mail the log out in csv format with time and SPL reading.
