- Choose a pitch shift in semitones and an output format.
- Click Change Pitch and download the result.
Frequently asked questions
- How is this different from the Change Audio Speed tool?
- Change Audio Speed shifts pitch as a side effect of changing speed (like a tape or vinyl record playing faster or slower) — the two are always linked. This tool shifts pitch independently, keeping duration exactly the same, using real time-stretching rather than simple resampling.
- What does "semitones" mean?
- A semitone is the smallest standard step in Western music — 12 semitones make one octave. +12 doubles the pitch (one octave up), -12 halves it (one octave down). Small shifts like ±2 are subtle; ±12 is dramatic.
- Will this affect audio quality?
- Time-stretching algorithms trade off some audio fidelity for independent pitch control — larger shifts (especially beyond an octave) are more likely to introduce audible artifacts than small ones. Try a smaller shift first if the result sounds unnatural.
- Is my audio uploaded anywhere?
- No — pitch shifting happens entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — processed in this tab | Yes, uploaded to process |
| Pitch shifts independently of speed | Yes | Varies — some free tools only offer linked speed/pitch |
| Account required | Never | Often, past a certain usage level |
