"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: The authorization for access to the built-in microphone will be confirmed by the iOS system at first boot. Please enable access to the microphone.
