For audio work, I use 4 programs: LMMS, yt-dlp, demucs, and audacity

My workflow usually goes yt-dlp to download audio/samples, then either audacity and demucs. Audacity I use for splicing the clips I need, and if its necessary, I use demucs to split stems either on the full song before splicing clips with audacity or splitting stems after getting the clips I want. I then use LMMS to sample and layer drums and other samples usually.
