Description
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.

Full-featured app. Trying to learn to use It's full functionality. Hopefully all the options work and are not just gimmicky.

Nice and solid app. I used to work with noise measurement devices which must be metro logically 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/the loudest frequency; - Has A and C type pondering settings - Can be calibrated at certain frequencies as well - Simple overview of all data

Underrated - fantastic, simple, and useful spectrum analyzer and weighted/unweighted SPL Meter. It will really come in handy in aid of my music production. Simply fit for purpose and no bloat. Something that's hard to come by in software these days. Thank you

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 even close to similar results both running on the same device! Useless!

Useless, there are no instructions on how to use it. And I'm a professional audio engineer.
