Only 60seconds of a file
I can only put 60 seconds in so if I have a 6 minute long mp3 file I can only view 60 seconds of it

Good but crashing
I love it but it crashes when I use the Octave RTA

Solid app
Tried a few spectrogram apps and this one is pretty solid. Lots of customization features.
Only small thing I would wish is that we can start replaying an audio file with the spectrogram completely scrolled back so that no one can anticipate what’s coming. But otherwise great job.

Audio Analyzer
I just purchased for $20. App does not work on my iPhone X with latest iOS. App does not pass a request to use the knternal microphone to Settings. The list of apps requesting to use the microphone remains empty.
An instuction to turn mic on in Setings appears but the app itself never adds itself to devices requesting the microphone.
When tapping the Gear symbol, the screen blinkx for 1/2 sec to an audio setup page but the returns to home screen. I tried several downloads and phone reboots.
No idea what to try next. There is no instruction manual or support email. Need to request a refund.

Total Waste of Money
As an Analyzer software, you have one crucial job to do. Show an accurate representation of the frequency spectrum. This app doesn’t even come close. I put this app on my tech bench and ran a high end Goldline tone generator into it, which the goldline and my audio interface was double checked with an oscilloscope for accuracy. This app shows major peaks and dips from 28Hz all the way up to 1.5kHz. It looks like a freaking roller coaster! It only gets mildly accurate after 1.8kHz. This basically makes the app unusable. I would have attached a screenshot if that option existed. SO aggravated. I have another Analyzer app that’s almost spot on to what the tone generator is putting out, but doesn’t have some of the options this app does (hence purchasing this one). Please fix the accuracy of this app or give me my money back

My "Go To" App for Live Sound
When I want to know what I am missing in a mix or to find a problem frequency, Audio Analyzer tells me and takes the guess work out of making needed adjustments to the mix at our church. ID ringing frequencies with the RTA or spectrograph or double-check your EQ at a glance. Intuitive to use and definitely worth the $4.99! Thank you for making such a great app!!!

So far, awesome
Exactly what I need to ring out FOH and monitor wedges. Waiting for micW i436 to arrive. 5 stars will stick if the app performs with the external mmm microphone.

Limited use
It's good for short loops and audio files but from what I can see that's about all. When you can only analyzer music that is less than 220 seconds long, not very practical. What am I supposed to do, chop up the song? Maybe I'm missing something here?

Importing issues
App crashes when trying to import files from voice memos on phone..please fix

love it!
I love this app, a very useful tool in many contexts.

Excellent app!
Very thorough and well thought out.

Wow. Nifty audio visualization
RTA is cool, though a little surprising you need to start recording to see it.
Flexible display and settings. Even trigger start.
Would like overlay for musical scale notes, ideally with optional transpose for things like B-flat trumpet.
And use of headphone microphone.

my favorite spectrum analyzer
I practice playing a Bb trumpet using this spectrum analyzer, chromatic tuner, metronome, and audio recorder. Studying my sound in the frequency and time domains helps improve my playing.
I would suggest the following feature to be added: Allow the user to preset the range of frequency and time. The current version allows the user to zoom in or out using 2-finger gestures. Because the region of interest for me is between 0 and 3 kHz, and because I need to view that region in detail, I need to adjust the frequency scale every time I use or reset the app. Furthermore, the 2-finger gesture sometimes bounces the scale such that the origin is not 0 kHz 0 seconds. Allowing the user to select the default range of frequency and time would save lots of time.
Thanks for a nice product.

shameful oversight?
The program is well done, looks good, and is ALMOST useful. The external mic input accessible via the earphone jack was not included. I'll give it 3 stars for what the software can do, but I'm taking 2 stars away for the their obvious stupidity. Had they included it I could analyze signals on wires, not just from the microphone. Yeah the camera adapter and USB mic might get me that ability too but why should I have to spend another $30-$50 because they screwed up? It's great software, I've no complaints about that, but functionally, it's just had a perfectly healthy leg amputated.
Fix this with an upgrade and it's a five star program.

Neat App
Very nicely done by the creators of the app. Several nice choices with the window functions, different options on displays, spectra, sonograms, and oscilloscope. Good value.

Bought and thought it realtime
Great engine, but can't get it working for realtime analysis, saw a long list of features but.... no RTA, that is why I'm disappointed.

Best audio bang for the buck
I have been an audio engineer for over 25 years. I've owned a jingle production company, a 2" 24 track recording studio and have been a live FOH/Monitor engineer for the better part of those 25 years. Obviously with the advancement of technology it gets better and cheaper every day. But this app has brought the power and ease-of-use and flexibility that only a year ago cost close to $1000. Can't believe it's under $10.

Handy audio utility
Thanks for this nifty little program. I used it to show the audio spectrum of an old Hammond organ with a stuck tone. Using Audio Analyzer in oscilloscope spectrum mode, with my iPhone on the organ bench, I looked for peaks, and one of them was right where the noise was centered. It told me the frequency when I tapped on the bar, and that helped me know where to look further to troubleshoot. There are other methods that I could have used, but this utility made it quick and simple.

Doesn't do what it's supposed to
Purchased this app because it's the only one I can find that advertises the ability to open files from other sources (saved via apple's voice memos app on an iPhone 6) but when I attempt to open the file, the app just crashes.
2014-08-07
It is what it is
This app looks really good if you reverse the colors on your phone. It's seems like a lot of money for an app that doesn't seem to do any more than the cheaper ones that do the same thing. I mean unless I can edit the junk noise out of my recordings manually I don't see the point for the extra money.

Works very well
I'm no expert, but it works very well for me. So far I've mostly used it for real-time spectrograms. Very nice audio analyzer.
2013-10-29
Good app, let's see more!
This is a nice app that delivers an easy-to-read spectrograph. In future releases, it would be nice to see:
1. External mic capabilities - the mic in the phone isn't that great, can I plug in my own via headphone jack?
2. Choice of scale for dB meter on the side. I'm not sure what scale is currently used, but I take my readings in dBA/dBC.
