How to Make a Sped Up Song (Nightcore Style) — Free & Online

Sped-up edits took over. Half the songs trending on TikTok are the sped-up version, artists now release official "sped up" cuts on Spotify, and the bright, higher-energy feel just hits in a short video. Making one yourself takes about two minutes and costs nothing.

This guide shows you how to speed up any song — and add that classic nightcore shimmer — right in your browser, with nothing to install.

#What "sped up" and "nightcore" actually mean

Both speed a song up; the difference is mostly degree and vibe:

• Sped up — the modern TikTok/Spotify style. The song is bumped up moderately (often ~110–130% speed), making it brighter, punchier, and more danceable. Vocals lift slightly but still sound natural.
• Nightcore — the original, more extreme version from the anime/electronic scene. Faster and noticeably higher-pitched, giving that signature bright, "chipmunk-adjacent," hyper-energetic sound.

They're the same tool, different intensity. Speed it up a little for a clean "sped up" edit; speed it up a lot for full nightcore.

#What you need

• A browser.
• The song file (MP3 or WAV).
• The free Sped Up / Nightcore tool. Everything runs on your device — your audio is never uploaded.

#How to make a sped-up song, step by step

#1. Load your track

Open the Sped Up / Nightcore tool and drop your file in. It loads locally and instantly — nothing leaves your computer.

#2. Set the speed

Push the speed up. Reference points:

• 108–115% — subtle "sped up," keeps the song natural. Great for sing-along clips.
• 120–130% — the punchy TikTok sped-up sound most edits use.
• 135%+ — full nightcore: bright, fast, higher.

Speeding up also raises the pitch, which is what gives the sped-up sound its lift and shimmer. Start at 125% and adjust to taste.

#3. Add a touch of air (shimmer reverb)

A small amount of bright reverb gives the sped-up track some "air" so it doesn't feel dry and clinical. Add a little reverb for shimmer — just enough to open it up. For full nightcore, a bit more reverb leans into the dreamy-hyper aesthetic.

#4. Export and post

When it sounds right, export. You've got a finished sped-up / nightcore file ready for TikTok, Reels, YouTube Shorts, or Spotify-style uploads.

#Tips for a better sped-up edit

• Don't overdo it. Past ~135% most pop vocals start sounding cartoonish. If you want bright-but-believable, stay under that.
• Match speed to the moment people will clip. The chorus or drop is what gets used in videos — pick a speed that makes that part feel best.
• Sped up ≠ just faster. The pitch lift is half the appeal. That's automatic here — speeding up raises pitch — so you get the full effect with one knob.
• A little reverb hides artifacts. Aggressive speed-ups can sound slightly thin; a touch of shimmer reverb smooths it over.

#Sped up vs. slowed + reverb vs. daycore

The sped-up family has slow-side cousins worth knowing:

Style	Direction	Feel
Sped up / nightcore	Faster + higher	Bright, energetic, hyper
Slowed + reverb	Slower + washed	Dreamy, nostalgic
Daycore	Slower + lower	Deep, dark, dreamy

Want the opposite vibe? Onomo has dedicated tools for slowed + reverb and daycore.
