I really like this app! I have downloaded a dozen different spectrum analyzers trying to find one that works well and simplifies sound system tuning. So many of them were not helpful or useless. This one works great. It made tuning my system very easy. I used to own an audio control rta 3050. And while this of course will not match pro equipment, it is much better than all of the other apps i have tried, free or paid up to $10, on ios and android. Thank you. Plus, no crazy annoying ads! Amazing. Of course, the best results will be obtained by using a calibrated microphone.
It's a really useful and apparently quite accurate tool (I calibrated it against a commercial SPL meter). Especially the A-weighting option. I'm giving only 3 stars because 1) there's absolutely no way to save, snapshot or otherwise export any readings or spectrum displays it shows, and 2) it doesn't have the option of keeping screen active, so every few minutes phone blacks out, you have to reawaken screen. The app "freezes" & loses all data, you have to close it and restart every time. So capturing a one-time "event" can be near-impossible...
If you are trying to find peak frequencies, then this app is not for you. No automatic hold options. Readout of peak freq is tiny.
I always like these sort of applications but can not seem to work this email one well as others.😡
Wery accurate !
