Audio Spectrum Analyzer dB RTA Reviews

For the pro version it cost $8.99. It might be worth it if you could hear it but you cannot hear anything I went to analyze something and listen to the play back and you can hear nothing not nothing. How can you know what it analyzed if you cannot hear it play back? It could just be sitting there r... Show more olling numbers your direction? If you use any analyzer on your PC or desktop you can hear it why can you not hear this one? So thank you for ripping me off of nine dollars!

I’ve used AudioSpectrumAnalyzerdBRTA for several years, paid for Pro, and found it to be excellent, until a recent upgrade that totally broke the spectrum analyzer aspect of it on both my iPhone 6s and iPad Air.

The problem is related to mic sensitivity, it will register the very loudest o... Show more f sounds. It may have to do with mic calibration or something, but I complained about it some time ago and nothing has been done.

I’m looking at other apps that actually work.

Unsure if there is a timed interval of the pop up advertisement to purchase the “Pro” version or if it is based on how many times you touch something in AudioSpectrumAnalyzerdBRTA , but it gets very frustrating trying to adjust a complex audio system, while constantly being asked if would like to b... Show more uy the pro version, which runs $8.99. Annoyances aside, the frequencies being gathered (by 3 additional Apple products, 4 total) seem to be less accurate than they should be. Adjusting 250hz on my head unit’s EQ effected the 125hz bar on the graph in AudioSpectrumAnalyzerdBRTA . Actively looking for another app that can be more successful.

AudioSpectrumAnalyzerdBRTA works great and has a very nice interface. The only and very big downfall is every 2 minutes, I timed it, AudioSpectrumAnalyzerdBRTA will stop working and a full page ad to “upgrade to pro version” covers the entire screen. You then have to press the close button to get... Show more rid of it and your good to go. Then 2 minutes later the same thing pops up. This will happen every 2 min as long as you are using AudioSpectrumAnalyzerdBRTA . Very very distracting and annoying. If it was for this it would be 5 stars.

I bought AudioSpectrumAnalyzerdBRTA. I never used it ( i did open it to look at its interface). I never agreed to a subscription. Suddenly, and without notification, i received monthly generic charges on my linked credit card. No app name was provided. Eventually i traced it to this. beware - s... Show more hady business practices. Too bad, i hoped to try it one day.

The complainers about the purchase ad are ridiculous. People don’t make apps without an expectation of getting paid for them. The loudest frequency tracking feature is super cool. The lack of a dB-C weighting is keeping me from buying. Level measurement for music needs it. If that ever shows up I’l... Show more l buy.

App works great, the graphs and functions are decent and well laid out. The one big frustration is the CONSTANT popup asking me to buy the pro version. Left the graph running on my desk for a moment, it popped up. Close it, watch the graph. A minute later, it popped up again. It ended up popping up... Show more and blocking the entire screen four times in under ten minutes.

If the popup was less frequent (maybe on app launch and every ten minutes or less), or costs less ($8.99 for pro), I’d rate this better. I’m not paying for the pro version simply due to how annoyed I was at the pushy attitude of AudioSpectrumAnalyzerdBRTA , and have since uninstalled it.

AudioSpectrumAnalyzerdBRTA works as it should but I have uninstalled it because it was so busy nagging me to buy the pro version I didn’t have time to love it enough to buy it.

Additionally, it will not allow music to play on the same device that is running AudioSpectrumAnalyzerdBRTA . Thi... Show more s may be unavoidable but disappointing.

The spectrometer it self is great, but how your app adds it in is horrible. Every minute, it tells me to get the pro version which makes AudioSpectrumAnalyzerdBRTA useless. The fristrating part is that it doesn’t even show any real ads. All it shows me is to upgrade to pro.

Additionally, I ... Show more don’t need or want ANY of the pro’s features. There are no ads, the accuracy is good enough and I don’t even know what FFT & RTA is! Make an option to just shush it up!

Very nice app. Gave me exactly what I was looking for, a way to tune my small living room surround sound system. The only gripe is the completely annoying “buy me, buy me” pop up ad that covers the entire screen every 30 seconds. Make the purchase option an icon in options and stop covering up the ...

Really like AudioSpectrumAnalyzerdBRTA however I noticed the frequency numbers do not match the spectrum in the RTA mode. The spectrum looks accurate but the numerical results are not. Also the feedback button doesn’t work under help so I couldn’t reach out to the developer that way to explain the... Show more issue. I think if they fix that issue this will be a great app.

I like the functions currently included. The ability to use a calibrated mic (external) and extend the scan range or bracket a scanning range would be helpful.

AudioSpectrumAnalyzerdBRTA is very intuitive and has plenty of fun tools to look at the information. The only issue I’ve noticed is that the spectrograph axis do not change from the normal FFT plot so it’s difficult to see exactly what frequency you are looking at when interrogating on the display...

Seems to work, there is a subscription option, but doesn't seem to be necessary.

Note the recording mic is on bottom of phone.

Would like options for dark background and graphs.

It gets four stars because IF you only wanted to use the not so great built-in microphone of your device then it seems to work very well. I was actually willing to pay for a way to unlock a Line-In feature but nothing told me that the feature exists. The fact that the spectrum plot can hold the p... Show more eaks is a real nice and makes your app more useful. The pop up is super annoying, but being an App developer myself...I understand how selfish people just expect a great feature rich App to be all for FREE (i gave up thinking i could be paid for all my hard work). Just for fun, you can check out my Free iPhone App FlipNshare ProVideo. I did uninstall AudioSpectrumAnalyzerdBRTA only because i need Line-In feature, please let me know if it’s actually available.

I wanna be able to see a spectrum of the output of the device I’m using. Say I want to compare the re-creation of the sample to the actual eq curve of the output from AudioSpectrumAnalyzerdBRTA I’m using to create the sound. Basically as a reference to see how accurate a re-creation of a sample is... Show more . Basically a pre-out spectrum.

I’ve been using this for the past two years. Works out great so many ways.

Using this with a 3000hz reference cassette tape to set cassette speed more accurately! I had a Walkman that music sounded too fast and sure enough it was! Had to learn FFT settings with line graph for best result! Great App! Thank you!!

Thank you thank you thank you for having a non-subscription purchase model!! Please never change that. It’s a plague.

I use this to help ring out every room before performers ever get to the show. Maximizing gain before feedback is as simple as pushing the fader nice and slow until you hear the ringing start, then AudioSpectrumAnalyzerdBRTA tells you exactly what you need to take out. Invaluable if you don’t have... Show more a digital mixer with a spectrum analyzer built in.

Excellent, excellent software, FFT and sound analysis work Elena... the tools are great... beautifully done! The iPhone 7 microphone is well calibrated. Using the 8k FFT in high resolution work, believe you could go to a 16k no problem. Thank you very much!

Easy to use and cost effective. I upgraded to premium and the unlocked version gives me lots of flexibility. Easy to use. I just have to leave my screen up. Lol

Awesome App and It's Free!
LOVE it!
Have tried many other but nothing like this for Free, as it was free it pushes me to upgrade to the full version even though it's not necessary as this free version gives me everything I need!
A BIG 👍

I have been using this for months! Best Spectrum Analyzer I could find. Works very well. Has calibration options. What more could you need?
