+         * can use mic-input or wav/aiff/snd/raw/mat file (with playback)
+         * time-domain waveform
+         * FFT magnitude spectrum
+         * 3D waterfall plot
+         * lissajous! (interchannel correlation)
+         * rotatable and scalable display
+         * freeze frame! (for didactic purposes)
+         * real-time spectral feature extraction (centroid, rms, flux, rolloff)
+         * available on MacOS X, Linux, and Windows under GPL
+         * part of the sndtools distribution.
