That’s fried rice, not white rice steamed or cooked in a rice cooker. I can imagine putting ketchup on a nigiri and immediately getting scolded in Japan.
With all due respect, I’m all for FOSS but DAWs don’t really have a good alternative. Recommending Audacity over FL/Live/Logic like saying Paint is a good free alternative for Photoshop. Doesn’t really make sense.
Iirc the only DAW that might barely be enough is LMMS which runs on Linux.
