Summary

Features

Estimation of the fundamental frequency (f0) of an audio signal, in real-time.

(the f0, not the perceived pitch)

(the f0, not the perceived pitch) Harmonics' amplitude

Waveform's period

Discrete Fourier Transform (DFT)

Microtonal tuning (supports scala file format)

Statistics

All views are optional so that the interface can be as simple as possible.
