Sound Analyzer App
By Dominique Rodrigues
Sound Analyzer App enables you to use your smartphone as a Sound Level Meter (SLM) and a Real time Audio Analyzer (RTA). Environmental noise, measured in decibel (dB) can be monitored in real time. The microphone sensitivity is adjustable by means of the calibration menu.
App with no adverts, banner or popups.
Features as sound meter (decibel meter):
A, C and Z (flat) frequency weightings,
Fast and Slow time weightings,
Equivalent A-weighted steady sound level (LAeq),
A-weighted sound publicity stage (LAE or SEL),
A-weighted sound publicity degree for a nominal 8-hour working day (noise dosimeter: LEP,d or LEX,8h).
Features as 1/n octave spectrum analyzer:
1/3 octave band spectra: Centre frequencies 25 Hz to sixteen kHz,
1/1 octave band spectra: Centre frequencies 31.5 Hz to eight kHz,
A, C and Z (flat) frequency weightings,
Fast, Slow and Impulse time weightings,
Equivalent continuous sound level (Leq).
If you are not familiar with Sound Pressure Level (SPL) indicators, use the default choice: LAF and LAeq indicators respectively for instantaneous and averaged noise measurements.
Warning: This App doesn't declare to be an alternative selection to an approved Sound Level Meter. The accuracy of the measurements relies upon closely on the specifications of the microphone/amplifier which aren't designed in a smartphone for Sound Pressure Level (SPL) measurements. This App is for indication only or for educational function. Use an permitted Sound Level Meter the place it's required.
If you just like the app, please price it.
