Real-Time FFT 1.3

Source:Dimitrios Ververidis

Using this program, one can view the waveform and the fast Fourier transform (FFT) of the signal, the so called spectrogram. The latency of FFT viewing is kept as low as possible, that is:
80 msecs for 8000 Hz,
100 msecs for 16000 Hz, and
130 msecs for 44100 Hz.

The highest amplitude frequency is verbosed live.

Linear and Logarithmic scale of FFT is supported.

The height of the upper (waveform) panel vs. the lower (fft) panel is configurable.
