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. (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:
