Speed on its own
This is the plainest of the effects here: the track plays faster and the pitch rises with it, and nothing else is added. No reverb, no bass, no colouring — which is exactly what a sped-up edit is, and why the results sound like the record rather than like a remix of it.
Between 120% and 150% is the usual range. At 125% a song sounds brighter and more urgent while still clearly being itself; past 150% most vocals lose their character and the drums start to sound like a machine gun.
When you want speed without the pitch
Not here. This page moves the pitch on purpose — the higher voice is the sound people are after. If what you want is a podcast, an audiobook or a lecture played faster with the speaker still sounding like themselves, use the audio speed changer instead: it can hold the pitch while it changes the tempo.
That is a genuinely different process. Keeping the pitch means rebuilding the waveform rather than simply playing it faster, which is slower to compute and unnecessary when the pitch change is the point.
How much shorter it comes out
Exactly in proportion. At 130% a four-minute song lands at just over three minutes; the figure is shown above the controls before you render anything. That matters when the audio has to fit a video of a fixed length.
The processing happens on your machine, so a long file is limited only by what your device can hold. Nothing is uploaded and there is no queue.
Frequently asked questions
How much faster should I go?
Between 120% and 150%. 125% to 130% is where most sped-up edits sit — fast enough to be obviously different, slow enough that the vocal still sounds like a person.
Can I keep the original pitch?
Not on this page, which raises it deliberately. The audio speed changer has an option to hold the pitch while changing the tempo, and that is the right tool for speech.
Why is there no reverb control?
Because a sped-up edit is dry by definition. Adding a room to it makes it a nightcore edit, which is a different page here with the reverb already dialled in.
Does speeding it up make the file smaller?
Yes, roughly in proportion to the speed, because there is less audio. A shorter file at the same bitrate is a smaller file.
Is the song sent anywhere?
No. It is processed entirely in this browser tab and never leaves your device.
