Publisher 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).

>>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 15000 Hz
