Have you seen Rod Stewart's model railway? It's a shame he's a cunt now but still... one hell of a model railway.

Fair. I always liked the thought that Eurorack is to music what golfing is to sport, i.e. prohibitively expensive and typically the preserve of affluent, middle-aged men.

I think the funding for this has since been extended for another 11 months but your point still stands.

Why does that coffee grinder sound like it's soundtracking a trailer for an A24 horror film?

CS2 for life. (GIMP is really good these days though)

The video demonstrates what you can achieve in one click but there are a number of tools built in (control over image resynthesis parameters, polygon/rectangular selection) for further work.

The most obvious application here is audio repair (Steinberg SpectraLayers does something similar, I think). I'm more interested in its application in experimental electronic music ("filling in" sections of audio using texture transfer within spectrogram images leads to some weird effects).

GIMP's implementation of the latter (derived from Paul Harrison's 2005 thesis on image texture resynthesis) pre-dates Photoshop's tool and this is a direct implementation of Harrison's technique.

In the example video, I select and "heal" a sine sweep that has been imposed over a recording of speech
