yea, i just made it with ffmpeg. i am aware that there's an almost inseperable correlation between lpcm and wav, but wav really is a a microsoft-made audio container that is simply so old that it only really supports a bunch of forgotten codecs... and lpcm
ffmpeg supports like 50 different variants of adpcm, it was really common, though not usually in places that the average person saw. for example it was really popular during the 5th and 6th gen of consoles
that file was created using;
