I'm adding a single static page with the list of all music collections you can download there, both touhou-related and not, and their last update dates for ease of tracking.
That page does not allow comments to keep it clean and simple. This post does.
Some album files in those collections are constructed from split-track web download versions (by trivial concatenation of the waveforms). Cuesheets for those files contain sample-precision track start and end times, so if you wish to split them back into tracks and are not satisfied with CD frame-level precision (1/75th of a second or ~13 ms) that is normally possible with conventional cuesheets, you can grab my splitter (barebones, but it works), compile it and use that.
It is now 2026. FLAC has decisively won the popularity contest (some would say it happened 10+ years ago). I'm not going to subject my downloaders to fully functional but obscure codecs any more, even if they are superior in some aspects. Newer collections use FLAC.

NO.

Most codecs that don't aim to squeeze the last drop out of their encoded files at any cost and instead balance speed/compression, FLAC included, are blazing fast on typical hardware. With multithreading enabled (or with multiple parallel encodings on earlier encoder versions) on a cheap 9-year-old CPU the official "slowest & best compression" FLAC method runs at well over 100 MB/s, close to read/write speeds of some spinning drives or 1 Gbps LAN. And its decode time doesn't depend on encode time.

Not worth it. The next best (easy) thing is to add "-p", which does exhaustive search in some region of parameter space. It easily quadruples encode time, while shaving ~200 kB off from a 400 MB encode (so first 100% of CPU time gives you ~30-40% reduction in space used, while next 300+% of CPU time gives you ~0.05% reduction in space used: >3 OOM worse ROI!). If you are encoding purely for yourself it doesn't even make sense from financial perspective: if you spend extra ~10s @ ~50W to save ~0.2 MB and electricity costs 10 cents/kWh (36 MJ/$) and HDD space costs 15$/TB, then you are spending 1.5e-5 $ on power to save 3e-6 $ on storage. Of course in practice everything is dominated by other considerations.

So that you can edit the metadata if you find a mistake and not break the whole torrent (the archive is just a simple container). In that case also please notify me to fix it for everyone in the next iteration.
