Real time frequency/spectrum analyzer allows you to record and play back the recordings while observing time signal and frequency spectrum in real time. The sampling frequency can be adjusted by the user. It starts at 200Hz and goes up to 44.1kHz. The recorded files can be deleted, if desired, from the app. The spectrum can be displayed in logarithmic scale (dB), with user specified number number of points of FFT (resolution), interpolation factor, integrated or differentiated and with various windowing functions. User configurable spectrum averaging is available. The app requires login information from IRISS Inc.
