sp_weights [arguments] [file]

Map auditory image onto spiral sector-weights contour.Read auditory image frames (using "output" model option so that frameshave a pipes header for frame dimensions).Use either gensai or genspl output, (but remember that theirdefault options are different, particularly pwidth, nwidth, and dencf).For each frame, write a sector-weights contour on the stdout, consistingof m binary shorts, where m is the given number of sectors.

The sector-weights are an economical representation of each frame (just64 numbers per frame) from which both loudness and pitch-strength can becomputed.
