Introduction
We built in trial a real-time colored display for sound spectrograms.
This apparatus was aimed at being an effective means for recognition of
various acoustic signals.1)
One of the main features of this apparatus is that the spectrogram is
displayed on a color picture tube in real-time in a colored contour form
resembling a contour map by converting the spectrum level to color (11 classes).
Another feature is that the spectrum pattern can be seen in sky-sign fashion
by shifting the instantaneous spectrum on time axis reserving it in a certain
time intervals.
