Description
This application brings the functionalities of a Sound Level Meter (SLM) and a Real Time Spectrum Analyzer (RTA) to your phone. SPL (dB) of the microphone (internal or external) signal.Suitable for acoustic measurements:
- SLM: traffic or ambient noise analysis (TNI, dBA/dBB/dBC, Leq)
- RTA: audio equipment frequency response analysis (spectrum, octaves, peaks, RMS)
This app has much more features (+) than the basic edition (no ads).
>>SLM main features:
• measurements in SPL
• 3 measuring modes (Dynamic, Average, Cumulative)
+ 3 weighting filter curves: dBA, dBB, dBC according to DIN-IEC 651

• current dB value, avg (Leq), min and max display
• Leq (wideband, RMS of the observation period)
• audio threshold trigger
+ sound level distribution chart

+ adjustable FFT size (up to 8192, about 5 Hz accuracy) , adjustable FPS (up to 20)
+ exporting of measures/chart data (CSV) and screenshot (PNG)
>>Data collection
The application relies on the mobile microphone signal. To achieve the best results consider the following:
1) Easy Calibration (only the first time): Some mobiles are automatically calibrated in the first installation phase. For details see the calibration section of the user manual.
2) keep your fingers away from the mobile microphone
3) silence your phone to avoid any ring tones, vibrations and other sounds
4) orient the phone microphone toward the noise source keeping the correct distance
5) click on the function buttons
>>Troubleshooting
1) Wrong SPL/RTA calibration: See the calibration section
2) No signals detected below 20dB or over 100dB: most smart phone microphones do not work under 20 dB or over 100 dB
3) Signal attenuation near band limits: the mobile mic may attenuate frequencies <100 Hz and >15000 Hz

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
