Frequently Asked Questions
How do I change the pitch of a song?
Upload an audio file, drag the semitone slider up (higher) or down (lower), preview it, and download the result. One semitone is one piano key; +12 or −12 is a full octave. Everything runs in your browser — nothing is uploaded.
Does changing the pitch also change the speed?
Yes. This pitch changer resamples the audio, so shifting the pitch up makes it slightly faster and shifting it down makes it slightly slower — the same way changing tape or vinyl speed works. That is exactly what nightcore (pitched up) and vaporwave/'deep' edits (pitched down) want. For small ±1–2 semitone key changes the tempo shift is barely noticeable.
Is the pitch changer free?
Yes, completely free with no signup and no watermark. It runs entirely in your browser, so there are no upload limits and your file stays private.
Can I use it to change a song's key for karaoke or covers?
Absolutely. Shift the track up or down until it sits in your vocal range, then sing along or record your cover over it. Pair it with the free vocal remover to build a karaoke instrumental in your key.
What audio formats are supported?
MP3, WAV, M4A, AAC, OGG, and FLAC. The pitch-shifted result downloads as a high-quality WAV file.
How do I make a nightcore version of a song?
Upload the track and shift it up about +3 to +5 semitones — that gives the classic sped-up, higher-pitched nightcore sound. Download the WAV, then turn it into a nightcore music video with Solmi.
