Sped up song maker

Why sped up songs took off

Sped up songs are exactly what they sound like: a track played faster than the original, usually with the pitch rising along with it. On TikTok and other short-video apps, sped up versions of songs became a trend of their own. A faster tempo packs more of the hook into a few seconds, the higher vocals cut through phone speakers, and the extra energy suits dance clips, edits and quick cuts. Some artists even started releasing their own official sped up versions alongside the original.

The look of a sped up edit is simple, which is part of why it is so easy to make. You don’t need reverb or heavy processing: it is mostly about choosing the right speed, deciding what happens to the pitch, and cutting the clip at the right place.

How fast should a sped up song be?

Most sped up audio sits between 1.1× and 1.3×. The Sped up preset on this page starts at 1.2× with the pitch following the speed and a +1 dB bass touch, and no reverb. Use the table to pick a starting point, then adjust by ear:

The speed slider goes all the way to 2× in 0.01 steps, so you can fine-tune to something like 1.17× if a vocal sounds best there. The tool also estimates the song’s tempo and shows the new BPM after the change, which helps when you want a clip to match a dance or a beat in your video.

Pitch up, or keep the original key?

There are two ways to speed up a song, and they sound quite different.

Follows speed (the classic sped up sound)

This is the default. It works like spinning a record faster: tempo and pitch rise together, following the rule semitones = 12 × log2(speed). The brighter, slightly higher vocal is what most people recognise as a sped up song, so this is the mode to use if you want that sound.

Set separately (faster, same key)

Choose Set separately and the speed only changes the tempo. With the pitch slider at 0, the song plays faster in its original key. This is useful when a singer sounds too squeaky at 1.2×, or when you need the clip to stay in tune with something else in your video. You can also pick a middle ground, for example 1.2× speed with just +1 semitone. Turn on Natural-sounding vocals (formant preservation) whenever you shift the pitch by more than a semitone or two. For key changes without any speed change, use the pitch changer.

Trimming a clip for TikTok

Short videos rarely use a whole song. Instead of exporting three minutes and cutting it later, trim it here:

1. Drag the handles on the waveform to the start and end of the part you want, usually the chorus or the drop. The handles also work with the keyboard.
2. Turn on Loop so the section repeats while you adjust the speed. Remember that the clip gets shorter as you speed it up: 30 seconds of the original at 1.2× plays in 25 seconds.
3. Add a short fade in and fade out (half a second to a second each) so the clip doesn’t start or stop abruptly.
4. Press Original (or the B key) to compare with the untouched track before you export.

Getting a clean sped up sound

Faster playback lifts cymbals and “s” sounds along with the vocals. If the result feels sharp, lower the treble by 1–2 dB or bring the high cut down to around 15 kHz. Raising the pitch also thins out the bass line, which is why the preset adds +1 dB of bass; go a little further if the clip sounds light on phone speakers. Keep the limiter on so loud choruses don’t clip.

Export a 9:16 video

In the download panel, choose Video and the 9:16 shape for TikTok, Reels and YouTube Shorts. The tool builds a 1080p MP4 with H.264 video and AAC audio, using the song’s cover art, your own image or a gradient as the background. You can add a title and subtitle and an optional audio visualizer. Video export works in Chrome, Edge and Safari; Firefox depends on your platform. On a phone, the Share button can send the finished file straight to another app.

If you only need the audio, MP3 at 320 kbps is the easiest format to drop into a video editor or app. WAV and FLAC are there if you want to keep full quality for further editing. Our guide to making edits for TikTok and YouTube covers the formats and posting side in more depth.

Sped up, nightcore or slowed?

Sped up edits are the lighter, drier relative of nightcore. If you want to push further, with a higher speed and a bright reverb, the nightcore maker starts at 1.25×. If you want the opposite mood, the slowed + reverb generator drops the tempo and adds a large hall. Many creators post both versions of the same clip.

No upload, no account

The whole process runs inside your browser using the Web Audio API and WebAssembly, so your song never leaves your device. It is free, there is no sign-up or watermark, and there is no limit on how many songs you speed up. Your last song and settings are restored on the same device if you refresh.

Keep copyright in mind: posting a sped up version of someone else’s song can infringe their rights. Use music you own or have permission to use when you publish.
