Image sonification → MIDI · the Blender flow, in a single app part of Regolith Highfield

Due preset, come in Blender. Puoi sempre regolare tutto a mano sotto.

🖼️

A · Visual

Il MIDI resembles the image in the piano-roll: pitch from the vertical band, chromatic scale, multi-track.

forma riconoscibile
🎧

B · Listen

Priority to ascolto: pitch from brightness, scale + nearest, merge. Catchy result.

tonale, denso
for deep skies: emphasizes bright peaks, sparse notes "in drops"

For the eyeball test: "Fit grid" makes the cells square (col÷ = fidelity), "Fit proportions" gives the piano-roll the same ratio as the image. Dark subject on a light background? Enable Invert. The whistle = large bright areas: "Soften audio" removes it without altering the shape.

The two paths (to mention in the thesis defense)

A · Visual — pitch dalla banda verticale (cell position) + scale chromatic: the piano-roll follows the image geometry. It demonstrates that the spatial structure is visible in the MIDI events.
B · Listen — pitch dalla brightness + scale with nearest + merge: priority to tonal listening, the drawing doesn't copy the silhouette. This is normal and intended.
None is "more scientific" in absolute terms: both are parameterized and reproducible. Declare which one you use and attach the .txt of the parameters.
