Audio Analyzer

Unusable for files with 5+ minutes length, can’t build spectrogram

Please consider adding formant tracking feature like VoceVista has

(English Follows) Très bonne application pour la phonétique. Je suis débutant pour la langue thaïe, cette langue à 5 tonalités. Pour un Occidental, cela est très difficile de savoir si notre prononciation est juste, car nos langues n’ont pas cette spécificité (ou si peu). Avec cette application, je peux enfin m’exercer seul et voir immédiatement si je suis sur la bonne tonalité. Je ne suis pas un ingénieur de son et je ne savais pas trop comment produire le spectrogramme parfait pour mes cours. J’ai demandé au concepteur de l’application s’il pouvait me donner le réglage pour ce type d’exercice. Il a répondu avec empressement et tout est parfait. (Le réglage est à la fin pour ceux qui sont intéressés.) Very good phonetic app. I’m a Thai language beginner learner, this language has 5 tones. For an Occidental as me, it’s very difficult to know if the tone I produce is right, because our languages have not this specificity. With this app, I can now practice alone and immediately see if I produce the good tonality. I’m not a sound engineer and I didn’t know how to adjust the setting. I asked to the app programmer if he can gave me the setting for this exercise type. He responded quickly and all it’s now perfect. (The setting follows if you’re interested). There are I think the best settings in your case: Window size: 4096 Window type: Hanning Sample rate: 44.1kHz FFT calculations interval 1.5ms Frequency display size: 2048 Amplitude scale: decibels Frequency scale: logarithmic -> when you want imitate voice flow Frequency scale: linear -> when you want imitate vowels formants in your sound When you are using linear frequency scale you have to zoom your spectrogram to region 0-5kHz (using pinch gesture) Best regards, Pawel Krzywdzinski

Superb in every aspect. Best RTA app out there.

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

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!!!
