Not entirely on topic here but the first thing I thought of: Years after his music program called Impulse Tracker had had it's heyday, some music magazine did a roundup of various resampling algorithms and Jeffrey Lim's resampling algorithm was included for posterity and to round things out so that it wasn't all only big-money players. Names like Kurzweil, Alesis, Akai, Roland, Yamaha, Sony, Pioneer, Philips, Tascam ... but there on that list at NUMBER ONE was the resampling algorithm from a little shareware program made by a hobbyist for making beep boop techno. (For those interested in the technical aspects of how to compare resampling algorithms, you take a sound, graph it, speed it up then slow it down, graph it again. Comparison of the two graphs would ideally be identical but in practice that's nearly impossible. Mainly you're looking for where frequencies got created that were not originally there.)
