Tudum is the onomatopoeic name for the audio logo Netflix introduced in 2015 to play before its original programming. Designed to be heard in living rooms in just a few seconds, the two-note hit became as recognisable as the red N on screen. Netflix later named its global fan event Tudum after the sound, and an extended theatrical version was created for cinemas. Online, creators detached it from the platform and began using it ironically, which kept it circulating long after it became everyday background noise.

The Netflix tudum sound effect is the deep drum and synth logo sting played before originals, now used as a dramatic intro or reveal cue in memes.
Tudum is a short, punchy logo sound built around two deep, resonant hits that land like a heartbeat. A low ta-dum drum thump is layered with a bright synth swell and a subtle orchestral rise, giving it weight and instant recognition in just a few seconds. It feels cinematic and important even when nothing important is happening, which is why it works as a joke. Placed before an ordinary moment, it tricks the viewer into expecting a premiere, a plot twist or a big reveal, then lets the anticlimax do the comedy.
