The description Sound Analyzer App Apk

Sound Analyzer App lets you 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 ads, banner or popups.

Features as sound meter (decibel meter):
A, C and Z (flat) frequency weightings,
Fast and Slow time weightings,
Equivalent A-weighted continuous sound level (LAeq),
A-weighted sound exposure level (LAE or SEL),
A-weighted sound exposure level 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 16 kHz,
1/1 octave band spectra: Centre frequencies 31.5 Hz to 8 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 selection: LAF and LAeq indicators respectively for instantaneous and averaged noise measurements.

Warning: This App does not claim to be an alternative to an approved Sound Level Meter. The accuracy of the measurements depends closely on the specifications of the microphone/amplifier which are not designed in a smartphone for Sound Pressure Level (SPL) measurements. This App is for indication only or for educational purpose. Use an approved Sound Level Meter where it is required.

Needs to be able to store data in semicolon separated format. Should have option to measure for 24h and store data.

No annoying ads works great. What a free app should be. No bullshit permissions.

Opens and graph moves, but does not seem to register any sounds on Galaxy S7. Manually gave mic permission, app never asked on install. I like the simplicity and options (specifically laeq) but can't try it out.

Update. Thanks developer for the explanation of permissions changing my rating to a five. Seems good, doing what its supposed to.. No ads or crazy permissions. Thanks Developers.. Update. I take back the permission comment above it has a permission it doesn't tell u about that allows it to write to external source.. read modify and or delete the contents of the USB storage .. Run es explore and u well see a warning. Dangerous. It would have been perfect has they left that out. Uninstalling..

Extremely useful app, this is easily accurate enough for my purposes. My only criticism is that, when zooming in on the graph, the lowest reading is always shown. I would like the graph to stay where I need it. However when paused the readout stays put and can be zoomed freely. Would it be possible for the graph not to reset after hitting play? Great work and many thanks.

Excellent app, very accurate, and has built-in calibration (which is also very accurate). I compared the app's readings to a professional sound meter, and it's right on. The only nitpick: I wish the font/display for the numeric decibel reading were a little larger; these old eyes can't read it without glasses.
