Audio Analyzer

I like to do measurements with a test CD on my turntable using my iPad. Pros: IPad is supported with Oscilloscope and Spectrum available. Also my attached RME ADI-2/4 audio interface that I use as Phono Preamp and ADC nicely works. Great that it supports the sample rate of 96kHz. Cons: Display of only one single channel of the stereo input and no simultaneous display of the right and left channel. This is true for Oscilloscope and Spectrum. So comparisons between both channels cannot be done easily. Also missing a X/Y display that is vital for antiskating adjustment. In Oscilloscope view of a sinus input signal the display is not triggered so no still standing Sinus can be seen. Summary: If the missing functionality would be available the price would be Ok for me. But with all the cons it was wasted money for me as I could not achieve what I had expected.

very good possibilities to analyze, but no connection to the airpods pro with ipad pro M1 2021

Without audiobus its mit worth the Money

there are a few analyzers out there, some very prizey and at different levels of complexity. this one here has a great balance between features and ease of use. the spectrogram is truly beautiful, with a great resolution on a retina screen. the options are sufficient and fast to reach. the other analyzers are perfect too, with all options one would need in most realworld situations. at this pricepoint this is a no brainer! i can only recommend this app!

This analyzer app has a very intuitive and userfriendly GUI. Everything is quickly accessable, with a maximum of 3 "clicks". App runs smoothly without any hickups (iphone 4s ios 7.0.4). Only wishes at this point, history for the spectrogramview and export as textfile. Both thumbs up. I love the Analyzer!

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

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

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.

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.

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
