CrackleBlaze aims to be fire you can sit any distance from.
A recording of a fire arrives with its hearth, its room and its particular armful of wood already fixed in it, and it loops. CrackleBlaze computes every crackle at the moment it happens, so a take never repeats and the same fire can be a hearth in a small cottage or a roof going up across the street.
That span is the instrument. Big, deep burning fires — burning houses and trees, where flames stack up for a lot of metres — sit at one end, and the warm, cosy campfire and the cosier fireplace fire in a small cottage sit at the other. The reference library says those really are different things rather than the same thing at different volumes: the large fires are nearly all roar, the small ones nearly all crackle, and the controls that move between them are measured rather than guessed.
It features 47 parameters across the combustion roar, the crackles, the sizzle of steam out of damp wood, the thump of a log giving way, distance and a full ADSR — with five fire colours taken as measured cluster centroids from the reference recordings and a Blend control that makes them a continuum. 18 factory presets ship, each fitted and then checked by rendering it back and measuring it.
