1 of 4, the path, on night: a rack of twenty-four filter cards, two taps, a reel, and a screen across a gap
2 of 4, the band, on paper: one module with eight settings on its face and one biquad in its drawer
the path, close: the band in hand lifted from the tray, the reel with its write head in red
3 of 4, the analyzer, on night: a bed of pins for the spectrum, and four frames shaped by the window
4 of 4, the phase, on paper: three beams answering one click, at once, a little late, and half a transform late
the band, flat: the module in plan and from the front, the biquad as it is wired, and the curve its five numbers make
the analyzer, close: the sound coming in behind, the sound going out in front, red at the tip of each pin
the phase, close: one pin a sample, standing for a push and hanging for a pull
