Free · No signup required · Your files stay private
What you can do with it
The pitch is pre-set to shift standard 440 Hz down to 432 Hz precisely, so you get the tuning without doing the cents math.
Only the pitch moves — the track plays back at its original length and tempo, so it stays in time with everything else.
Convert song after song to 432 Hz and download each as MP3, WAV or FLAC, with nothing added and no quality lost to a watermark.

Frequently asked questions
What is 432 Hz tuning?
Most music is tuned so the A above middle C sits at 440 Hz. 432 Hz tuning lowers that reference slightly, so the whole track sounds a touch lower and, to many listeners, warmer.
How do you convert 440 Hz to 432 Hz?
We shift the pitch down by about 31.8 cents — a hair under a third of a semitone — which lowers 440 Hz to 432 Hz across the whole song without touching the speed.
Is the 432 Hz converter free?
Yes. Retuning to 432 Hz costs nothing, there is no watermark and no signup — upload a song and download the converted file.
Does it change the speed of the song?
No. Only the pitch moves down to 432 Hz; the tempo and length stay exactly the same.
Will it lower the quality?
The pitch shift is clean, and you can export to WAV or FLAC to keep it lossless. Nothing is added to the file.
Can I fine-tune the amount?
Yes. It opens pre-set for 440 to 432 Hz, and the cents slider lets you nudge the tuning further if you are matching a specific reference.
Do my files stay private?
Your file is processed on our own servers and deleted automatically, and nobody else sees it. The download link is unguessable and is never listed or shared anywhere.

Perfect even with opera, jazz, etc. It's like a dream...🥹
Perfect même avec de l'opéra , Jazz etc... Comme un rêve ...🥹
It's a bit annoying that I have to select the conversion type every time, and my initial selection doesn't stick. Other than that, everything's fine.
קצת מעצבן שכל פעם צריך לבחור סוג המרה ולא נשאר מה שבחרתי ראשון חוץ מזה הכל טוב
If you want to analyze everything from the individual instruments to the vocal arrangements in a song, VocalRemover is exactly what you need. You can listen to every component of your song in detail. I don’t usually leave comments, but I decided to leave one here because I imagine that if someone has made it this far and has doubts or needs encouragement to use VocalRemover, they should go ahead and do it—they won’t regret it!!
Si buscás estudiar desde cada uno de los instrumentos hasta cada arreglo vocal de una canción, vocalremover es lo que buscás. Podés escuchar cada componente de tu canción al detalle. No suelo dejar comentarios, pero decidí dejar uno acá porque imagino que si alguien llegó hasta acá y tiene dudas y necesita ánimo para usar vocalremover que lo haga tranquilo, no se va a arrepentir !!
Really great—the best of the best
