How to make sped up audio
- Drop a song into the upload box — it decodes locally in your browser.
- Pick a speed chip — 110%, 120% (the TikTok favorite), 135% or 150% — or set an exact value on the slider.
- Press Apply effect; the pitch-preserving stretch takes a few seconds on long files.
- Preview the result, then download it as a 320 kbps MP3 or WAV.
This sped up audio maker is built around a time-stretch engine that keeps the original pitch intact, so vocals still sound like the artist — just faster. That separates a proper sped-up edit from a simple fast-forward, where everything drifts up into chipmunk territory. The processing runs entirely on your device through the Web Audio API: no upload, no account, no file limits.
Typical uses: sped-up song versions for TikTok and Reels, quicker listening for long voice memos and podcast segments, or testing how a track feels at a higher tempo before a DJ set. Pair it with the Audio Trimmer to cut the exact section your edit needs.
FAQ
Does speeding up a song change the pitch?
Not with this tool. It uses a pitch-preserving time stretch, so the tempo rises while vocals keep their natural pitch — no chipmunk effect. If you actually want the pitch to rise with the speed, that is the nightcore sound, and our Nightcore tool does it.
What speed do sped up TikTok songs use?
Most sped-up edits hover around 120% of the original tempo, which is this tool's default preset. There are also chips for 110%, 135% and 150%, and the slider lets you pick any value in between.
Why does processing take a few seconds?
Pitch-preserving stretching analyzes and reassembles the waveform rather than simply playing it faster, and it runs on your own device instead of a server. Short clips finish almost instantly; a full-length song can take a few seconds depending on your hardware.
Is the sped up audio maker free and private?
Yes — free, no signup, no watermark, unlimited use. Your file is processed locally in the browser and never uploaded anywhere; the finished track downloads directly as a 320 kbps MP3 or WAV.
