Mechanical Switch Sound Profile Synthesizer
Experience and compare mechanical keyboard acoustic signatures before buying or building. Synthesize deep "thocky" bottom-outs, high-pitched "clack", tactile leaf snaps, and see how plate materials, case foam, and Krytox 205g0 lubrication shape the frequency spectrum.
