📝 About this app
"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone.
With its simple operation, you can easily measure and evaluate your sound environment.
This app measures the frequency response in 30 split band scale of 1/3 octave in real time. It can also display the FFT analysis results.
It supports calibration for 1/3-octave bands. By adjusting the characteristics to match not only the built-in microphone but also your external microphone, it achieves high measurement accuracy.
"Audio Frequency Analyzer" can be used for various applications, including sound room tuning, speaker settings, audio equipment testing, stage setup measurement, sound mixing environment evaluation and noise environment investigation.
Features:
- Frequency spectrum response measurement of 1/3 octave unit, 30 bands. (OCT)
- FFT Analyzer (FFT)
- Observation frequency range: 20 - 23000 Hz
- Logarithmic amplitude display.
- Touch-scroll function to adjust visible amplitude ranges.
- Display the measured value of 1/3 oct bands at OCT mode. (dB@OCT)
- Function to change the graph slope at FFT mode. (Slope): -3dB/oct (less than 1kHz), +3dB/oct (1kHz or higher)
- Peak hold function. (Hold)
- Average display function. (Avg): Time linear averaging. Fast-2.56sec, Slow-12.8 sec
- Display response control. (Fast/Slow)
- Reset of Measurement display position. (Scroll)
- Snapshot of Measurement display. (Snap)
- Calibration function in OCT mode. (Calibrate): 1/3 octave band offset and total offset setting.
- Supports built-in microphone, headset microphone, and external digital audio connection.
Note:
The first time you access your microphone and photos after installing the app, the iOS system will ask you for permission to access them. If you have not enabled this setting, the app will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in the iOS setting "Settings > Privacy & Security > Photos or Microphone".

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
