Bought as part of a bundle with db meter and light meter The app won t open on iOS 10 on an iPhone 6 Wasted 5 bucks at this point     Doesn t work Onomike

Used warble tone sweep and white noise to equalize speakers Would be nice if the peak and hold function had a release or reset button have to cycle through FFT or bandpass Otherwise I found the FFT filter to be really nice for EQ ing my loudspeakers Great buy replaces a pricey test CD that I can t find anymore think I loaned it out                 Very good functionality great buy GEMEINMIE

Gives almost no information below 70 hertz I am trying to decide whether I need a sub woofer and how much my speakers roll off below 70hz It shows a straight response from 70 to zero which is wrong and you can t select a reading below 50 Has the same problem at the upper end of the audible range Fine for mid range analysis I suppose but this usually not where the problems are in audio systems                     Detailed Bass and treble analysis is lacking CSDinSing

I ve used bar graph audio analyzers on the iPhone and the one in this app is as good as any I ve seen but the real winning feature is the FFT display It allows ready identification of the exact frequencies that are the components of the sound you are hearing Highly recommended                     I am really impressed Kerly31415

As a musician it helps me find any annoying freqs I tested this against a real audio spectrum analyzer It s so close to the grass speck I was totally blown away So keep on developing this apps I support you guys                     Really good vinamissapp

This is fun to play with I m not going to tune my piano or calibrate my audiometer with it but it s useful to see what the main frequencies are in everyday sounds and noises Its also a great conversation starter when you start whistling into your phone                     Fun and useful ragofatino0

Fantastic app                     Love this app 123Jovi123

It is very simple to use stable to run the sound level is only several dB off from a commercial sound meter Wish to add a manual calibration setting and a time based filter                     Works great on iOS 10 2 1 nd_liu

Please consider adding quarter tones common in oriental music and this app would be a universal best                     The best sound analyzer ever farismismar

This app saved me from spending 175 on a light switch by leading me to the source of a high pitched whine 8 4 KHz from a motion sensor I am very grateful for this app                     Great Spec Analyzer App CZ101

I just downloaded this app because i wanted to identify a mysterious high pitched tone that was audible in my house It worked great The tone was clearly visible as a peak around 6400hz and then i was able to confirm using a tone generator I m just a casual user but the app present a feature set that would appear to satisfy more serious users too I recommend this app and works great                     Work perfect lyka144gghjuyrttr

This app is very heplful for me This app has many advanced features which are normally only found in much more expensive sound analysis software It is a powerful real time audio analysis app                     audio analysis app nhk.kute123

Back in the days I used to play with many audio analysis tools in the PC This is an app extremely simple to use and fun while having enough features to make it a worthwhile tool for real sound analysis in real time Well done                     So well done and fun Hobss

Love it I learn the basics about sound using this app                     Awesome RickQTran

Perfect A very useful app that help you detect and analyse those real time sound frequency Which is perfect for tuning and its really helping me a lot Nice app and definitely worth the price                     Best sound analyser Rulaiduswhite

It is recommended to use the decibel meter Beautiful design easy to carry Users can measure the decibel ambient and analyze audio anytime anywhere                     Awesome MalcolmJoan

A very professional audio measuring instruments Providing the most professional measurement data Unique design easy to carry Use is also very convenient                     Amazing PolyDome

I appreciate its design concise interface intuitive and easy to use especially FFT Plot it can be clear and intuitive to show the changes in audio and offers fast and accurate spectrum analysis It can be comparable to professional sound analysis software                     Professional Bobs King

This is an impressive highly functional spectrum analyzer On my iPhone 6s it is extremely fast even when generating high red 4096 FFT spectra It can also be set for 2048 1024 or 512 resolution The alternate bar raps display can be set for 1 octave 1 3rd octave or 1 6th octave display and is fast and responsive at any resolution The app allows quick touchpad selection of specific frequencies or specific bands while in bargraph mode for measuring and tracking the level in that band only Both bargraph and continuous spectral displays have selectable peak holding display capability In addition there is SPL average display showing the average SPL in dB A The display panes are beautifully designed so the app looks professional According to the maker the analyzer is compensated for the Apple internal microphone This is an amazing bit of programming which makes a iPhone equal or exceed the performance of a piece of audio test equipment that would otherwise cost many hundreds of At the extremely reasonable price of 2 99 it s a fantastic bargain for anyone needing audio measurement tools Personally my wish list for future releases would include switchable weighting filters for the SPL measurement dB C for sure and possibly dB Z as well as a way to capture export images of the spectral displays for future reference However as it is today this is a wonderful app for anyone working in the audio world Thank you for making it available Love it                     Excellent Audio Spectrum Analyzer App Lotus Seven

But it would really be nice if it would quite asking me every 5 minutes if I have a problem I d like to report Still can t figure out what s prompting it to ask but it s pretty annoying when I m working with a band trying to get them mixed down                     Great App 8B1TATX
