/**
spectgen is used to create spectrograms, which are 3d plots of
amplitude against time and frequency. Spectgen takes a waveform and
produces a track, where each channel represents one frequency bin.
By default spectgen produces a "wide-band" spectrogram, that is one
with high time resolution and low frequency resolution. "Narrow-band"
spectrograms can be produced by using the -shift and -length options.
Typical values for -shift and -length are:
