About this app

This application, can determine the total noise level, and be used as a spectrum analyzer for the microphone signal.

Rate the quality of the microphone bandwidth of your device, using a spectrum analyzer.
Determine the dynamic range of the sound in different frequency bands.

It can be used as a VU-meter in FAST mode and as a RMS-meter in SLOW mode time weighting.

Available user equalizer, for microphone calibration to get more accurate results.

Support bluetooth handsfree microphone.

This app allows you to measure:
- the total sound level
- sound level in selected bands ( size band one or 1/3 octave)
- minimum & maximum level of the measurement period
- measuring of frequency with maximal level.
- shows the spectrum of the signal.

This App allows set next properties:
- size FFT 4096 or 8192 ( frequency resolution 10,7 Hz or 5,4 Hz )
- Fast or Slow time weighting ( t = 1 sec and 0,125 sec )
- enable A, C, or ITU-R 468 frequency weighted

This App allows you to enter a correction (calibration) AFC, to account for the uneven frequency response of the microphone and recording device path.

This App not guarantee accurate readings which can be used for scientific measurements, as the device can be carried with dynamic signal processing
(automatic gain control,limiter NR), which not controlled by the program.

Ratings and reviews

Nice and solid app. I used to work with noise measurment devices which must be metrologically calibrated and when I remember results for simple, common conversation, I see that this app measures very close to what it should be. Pros: - Has frequency diagram (2 chart types); - Measures highest and lowes values, for "total" noise and each selected/loudest frequency; - Has A and C type pondering settings - Can be calibrated at certain frequencies as well - Simple overview of all data

This is a great app. It's giving consistent results compared to other pro spl apps like decibelX. It has A/C weighted measurements and slow/fast response time. This really helped me calibrate my studio monitors. There are also some other nice features too.

After wasting time with an assortment of these so called audio tools I can confirm that none of these work. I have 4 different devices some are a month old and what I saw was so far off from my Real RTA that i could only laugh when I thought about the shill reviews (or people who have no clue) saying they tune systems with these apps. I can't even imagine what it sounded like after they were done. No 2 apps showed showed even close to similar results both running on the same device! Useless!
