The Analyzer is a combination of a sound pressure level (SPL) meter and a full range multiple bands frequency analyzer. It is mainly designed for audio professionals who need to evaluate different working environments (e.g. studios, live stages)... that’s why it’s perfect for anyone who’s in need of acoustical analysis!! It is easy to use and comes with amazing features only known from professional acoustic tools.

Use the Analyzer for measuring stages, testing speakers, setting up your hi-fi system, evaluating sound mixing environments, analyzing your instrument... or for measuring the noise your neighbor makes with his new stereo!

The Analyzer is pre-calibrated for all iDevices, but it includes a calibration function as well. It comes with a highly intuitive user interface with zoom gesture control, individual color settings, reticle zoom and many more exciting features. The Analyzer can store, load and export measurement data and supports iCloud storage.

Combine the Analyzer with external microphones such as the MicW i436 or Microtech M372 for better measurement performance! Or use it with external USB audio hardware like the RME Fireface UCX or the Alesis IO dock, change the measurement scale to dB (FS) and use it as a studio Realtime Analyzer!

Good app

I been using this app for 4 years and never had an issue. It’s a good alternative when bringing my whole laptop, interface and mic setup would be too much or not practical.

It's $25 to make useful

I'm pretty disappointed that after purchasing the app at $15, I had to put $10 more in just to get the calibration file for Mic W I-436. Really, for $15, they should include it. Especially considering this app is only a basic RTA (no other analysis tools). And I'm really not sure this app is any more accurate then a free one. Feeling a bit taken advantage of.

The Graphic Equalizer Keeps Disappearing

The graphic equalizer keeps disappearing. To make the GEQ work again, I have to delete the app off my phone and then download it again. This is totally unsatisfactory.

Recommend that you do not purchase the graphic equalizer which is an in-app purchase. I’m using this for live sound overall level setting, so the GEQ is important to me.
