Nightcore: What It Is and How to Make One Online

Nightcore is a music genre created by speeding up a song to 1.25×–1.5×, which raises the pitch and creates a high-energy, anime-inspired sound. You can make a nightcore version of any song in under 2 minutes — no software, no upload.

Nightcore started as a YouTube phenomenon in the early 2010s, where creators would speed up pop and EDM tracks and upload them over anime visuals. It grew into a full genre with millions of dedicated listeners. The technical process is simple: increase playback speed, which simultaneously increases tempo and pitch. sound-goods Speed Changer does this entirely in your browser.

How to make a nightcore song — step by step

Open sound-goods Speed Changer

Go to sound-goods.com/change-mp3-speed-online and drag your MP3 onto the editor. Supported formats: MP3, WAV, OGG, FLAC, M4A. The waveform appears immediately — nothing is uploaded.

Set your speed

Drag the speed slider or click the preset buttons. For classic nightcore: 1.25×–1.35×. For more intense nightcore: 1.4×–1.5×. The live duration preview shows the new length instantly.

Leave the pitch slider at 0

The pitch rises automatically when you increase speed — that high, energetic vocal sound is exactly what happens when audio plays faster. You don't need to touch the pitch slider for nightcore.

Preview at full speed

Click Play to hear your nightcore version before exporting. Adjust the speed slider until it sounds right — most classic nightcore tracks land between 1.25× and 1.35×.

Export MP3

Click Export MP3. The file downloads instantly, named with the speed ratio (e.g., song_135x.mp3). Ready to post, stream, or share.

1.35×	+5.5 semitones	High-energy, classic anime feel	EDM and hyperpop nightcore
1.5×	+7 semitones	Very fast and high — chipmunk territory	Extreme nightcore
2.0×	+12 semitones	One octave up — fully chipmunk effect	Meme edits, not typical nightcore

Nightcore vs. slowed + reverb

These are the two dominant "fan edit" genres and they are exact opposites:

Nightcore — speed up (1.25×–1.5×), pitch rises, tempo increases. High energy, anime aesthetic.
Slowed + reverb — slow down (0.75×–0.85×), pitch drops, tempo slows. Melancholic, lofi aesthetic.

Both are created with the same tool — just drag the slider in the opposite direction. See our guide: How to Make Slowed + Reverb.

Tips for better nightcore

Songs with already-high female vocals tend to produce the best nightcore. The pitch shift makes them sound more characteristically "nightcore."
EDM, pop, and hyperpop translate better than slow ballads — the increased tempo makes the rhythm more exciting rather than chaotic.
1.25×–1.3× is the sweet spot for most tracks. Above 1.5× starts sounding unnatural rather than energetic.
You don't need reverb for nightcore — that's the slowed genre. Keep it dry and punchy.

Frequently asked questions

What is nightcore?

Nightcore is a music style created by speeding up existing songs by 1.25×–1.5×, which raises both the tempo and pitch. The high, energetic vocal sound and faster beat give it a distinctive anime-inspired feel. It originated on YouTube in the early 2010s and grew into a full genre.

Does nightcore require a specific tool?

No. Any tool that changes audio playback speed will produce a nightcore effect. sound-goods Speed Changer does this in your browser with no upload, and the continuous slider lets you dial in the exact speed rather than choosing from fixed presets.

Is my file uploaded to a server?

No. All processing runs locally in your browser using the Web Audio API. Your audio never leaves your device.

Can I make nightcore on my phone?

Yes. sound-goods Speed Changer is fully responsive and works on Android Chrome and iOS Safari. Load your file, set the speed, and export — the workflow is identical on mobile.

What's the difference between nightcore and sped-up versions?

They're the same thing. 'Nightcore' is the original genre name from the 2010s. 'Sped-up' became popular on TikTok and Reels as a separate trend, but the technical process — increasing playback speed — is identical.
