(Sept 2008): Now loads JPEG, GIF files (still save only to BMP). Recents files menu and cute selection.
(May 2003): Blue = Noise. Bandlimited noise, unlimited variation. Rumble, grumble, roar, screech, buzz, hiss, and susurration.
What is it?
Coagula is an image synth. This means that it is both a simple image editor, and a program for making sound from those images.

How: Coagula uses one sinewave (beep) per image line, one short blip per point (pixel) on the line.
Red is left, Green is right, Yellow is green+red, so it's in the middle.
Blue makes each sine into a narrow noise-band, so you can create hard noise or organ-like sounds.

Get started: Make some marks on the black canvas. Rotate, zoom and multiply the parts. Hit F5 and hear the light.

Tools: Use Filter images to shape areas. Use Echo tool to copy pixels several times. The brush has lots of options.

Coagula is freeware.

Coagula plans.
Preliminary and subject to changes. No time schedule.

• Play the image by mouse drag
• Multiple layers, to manage parts of sound separately.
• The most requested feature is to make images from soundfiles. This is harder than you think, and doesn't turn out very good. I want to give it another try sometime.
