+View the real-time (FFT) frequencies of the recording sound. Show the main (dominant) frequency.
+Real-time audio / recorded spectrum analyzer. Measure the magnitude of an input signal versus frequency within the full frequency range of the instrument. Display frequency (Fourier) bins (buckets). In the settings one can change the number of requency bins to display.
