Nightcore Generator: Make Sped-Up Songs in Your Browser

Make a nightcore or sped-up version of any song: raise the speed, which raises the pitch with it, add a touch of reverb and brightness, preview it as you go, and download the result as MP3 or WAV, without uploading the song.

Nightcore Generator: Make Sped-Up Songs in Your Browser: The track is played faster, which raises its pitch at the same time, as when a record spins faster; 125% raises it by almost four semitones. A little treble is added for the bright nightcore sound, and reverb can be blended in. The preview and the download use the same processing. Runs 100% locally in your browser with zero server file uploads.

Your file is processed in your browser and never uploaded. Changing the speed changes the pitch too, as in slowed and sped-up edits. MP3 files are encoded with LAME, free software under the LGPL, loaded as a separate file; its source is at lame.sourceforge.io. Only edit music you have the right to use.

Frequently asked questions

What speed is nightcore?

Usually 120% to 130% of the original. 125% is the default here; sped-up edits often use a little less, around 110 to 120%.

Can I speed it up without changing the pitch?

Not in this style, which changes both. To change only the tempo, use the audio speed changer.

Can I upload it to YouTube or TikTok?

Only with the rights to the original song. Speeding it up does not make a new work; rights holders can claim or remove it.
