This tool speeds up a song so it plays faster. You load a track, drag the speed up, and hear the result right away. It runs in your browser, it's free, and there's no signup or install. MP3 and WAV both work.
To use it: upload an audio file, wait for the waveform to load, then raise the speed. Play it back to check how it sounds, adjust until it feels right, and download the faster version.
This is useful for nightcore-style edits, where a track is pushed faster and higher in pitch for that bright, sped-up sound. It also helps when a song drags and you want a tighter, more energetic version to post or use as a short clip.
A practical tip: small changes go a long way. Going much past 1.3x or 1.5x can make vocals sound thin or chipmunky, so raise the speed gradually and listen instead of jumping straight to a big number.
The most common question is whether speeding up changes the pitch. Playing a song faster raises its pitch by default, which is the classic sped-up effect. The slowed + reverb effect in the studio does the opposite if you ever want it lower instead.
Since the studio also trims tracks and adds reverb, bass boost, and 8D, you can stack those after speeding things up, for example a faster track with a touch of reverb.
