Decibel X PRO - Geluidsmeter

Ive been trying to calibrate my studio monitors the whole day and every time I have both sides exactly the same, with a 1k sine wave and myself positioned outside the sound field, the room analysis at the listening position measures a difference up to almost 5dB between both sides. Its impossible to get them even with this app.
Another extremely annoying thing is that, while in use, de screen goes black and everytime I can crawl under my desk back and forth to turn it on again. Not very practical.

I like this app. But in order to by able to use it for professional purposes, I need to be able to measure equivalent (average) sound levels like LAeq / LAr,LT, including the equivalent spectrum in octave or terts. It now only shows instant levels Lp, with only an “overall” (total) average. Also it would be nice if i could save the measured values per timestep/frequencyband in stead of the graphics only. So keep up the good work and bring this app one step higher!

I need to compute Leq (A) over 3 min because of local regulations. The averaging interval for Leq, however, is not user selectable. Therefore the app is unuseable for me. It would be nice if I had been able to discover thus ffom the specs!

Crashes every time, update did not solve it.
I regret my purchase.....
iPhone 5s, version 12.1.2.

Since the last update I’m not able to open the app anymore. I’ve paid for the complete version a while ago and this cannot be tolerated. So, get rid of the bugs and make it work again. By the way it’s running on my iPhone 6s with iOS 12.1.2

Heel behoorlijke mogelijkheden. Crasht bij het omschakelen van 'classic' naar 'modern' theme.
Als je de setting savet, dan moet je de app deinstalleren en installeren om m weer aan de gang te krijgen.
