draw it, hear it, see it back

Draw on the sheet and it sings what you drew, left to right, higher marks higher. Underneath, the sound draws your picture back. Whistle a line, or keep what you made as a file.

DRAW

WHERE IT SINGS

Lowa hum you can feel; the drawing comes back thick and smeared at the bottom

Middleplain to the ear and to the eye; a voice's range

Highthinner and brighter; the lines come back sharper

The hidden topsharpest to the eye, faint or gone to many ears and small speakers

What the sound draws back

A spectrogram of what is playing, live, on the same scale as the sheet.

The file is the drawing: drop it on perception (its log scale) or any spectrogram, and it is there.
