What is nightcore?
Nightcore started in the early 2000s with sped-up eurodance remixes, and today the name covers any faster, higher-pitched version of a song, often paired with anime-style artwork. The sped up versions on TikTok follow the same idea with slightly gentler speed-ups.
To get the effect, the song is played faster like a record at higher RPM, so the pitch rises along with the tempo. At 1.25× (the classic setting) the song is 20% shorter and sounds about four semitones higher; at 1.10× or 1.15× you get a subtler sped up version. You can pick any value from 1.05× to 1.60×.
Raising the pitch makes the bass lose some presence, so you can add a bass boost of up to +10 dB to bring the punch back. The final volume is adjusted so it never clips.

Frequently Asked Questions
What speed does nightcore use?
The most typical is 1.25×, though many versions range from 1.15× to 1.35×. Sped up versions on TikTok usually stay around 1.10× to 1.20×.
Can I speed up a song without raising the pitch?
Yes, with the speed changer and the “Keep pitch” option. Nightcore, on the other hand, raises the pitch on purpose.
