About Audio Frequency Analyzer
"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone.
This app can measure the frequency response in 30 split band scale of 1/3 octave in real time. Also it can be displayed the FFT analysis result.
"Audio Frequency Analyzer" is available in a variety of applications, such as sound room tuning, speaker settings, audio equipment testing, stage setting measurement, evaluation of sound mixing environment and Investigation of noise environment.
Features:
- Frequency spectrum response measurement of 1/3 octave unit, 30 bands. (OCT)
- FFT analyzer. (FFT)
- Frequency display : 20 - 20000 Hz (X-axis)
- Logarithmic amplitude display. (Y-axis)
- Function of touch-scroll to adjust visible amplitude ranges.
- Display 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)
- Display response control. (Fast/Slow)
- Reset of Measurement display position. (Scroll)
- Snapshot of Measurement display. (Snap)
- Calibration function at OCT mode. (Calibrate) : 1/3 octave band offset and overall offset setting.
- Display Info view. (Info.)
- Supports built-in microphone, headset microphone, and external digital audio connection.
Note:
At the time of the first access to Microphone and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app cannot access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy & Security > Photos or Microphone".
