Finally a real FFT spectrum analyzer at a fun price! This compares well to apps at ten times the price and delivers an FFT spectrum of what the mic hears with 43 Hz bin resolution, automatic labeling of the peak frequency, and a built-in sinewave generator and SPL meter! Only drawbacks: no vertical axis labels, so not really useful for fine EQ (the y-axis is logarithmic, and appears to cover around 100dB); no options to change FFT length or window shape.
