How to convert a song to 432 Hz

- Keep 440 → 432 Hz, switch to 432 → 440 Hz, or pick Custom and set any reference with the slider.
- Press Convert tuning — the cents shift is shown so you know exactly what changes.
- Preview the converted track and download it as MP3 or WAV.
This 432Hz converter performs a tuning-reference shift: it moves the whole track by the small number of cents between two reference pitches while leaving the tempo and arrangement exactly as they were. Going from 440 Hz to 432 Hz nudges everything down by roughly 32 cents — a subtle, even change, not a slow-down. The work is done with a pitch shift that preserves duration, entirely in your browser, so your music is never uploaded. It is popular with listeners who prefer a 432 Hz tuning, and the reversible 432 → 440 Hz direction plus a custom 430–446 Hz target make it useful for matching a recording to an instrument or to another track. For larger pitch moves by whole semitones, use the Pitch Shifter instead.
FAQ
How do I convert a song to 432 Hz?
Drop your song onto the page, keep the default 440 to 432 Hz direction, and press Convert tuning. The track is retuned down by about 32 cents while the tempo stays the same, then you can preview it and download an MP3 or WAV.
What is the difference between 440 Hz and 432 Hz?
440 Hz is the modern standard tuning reference for the note A. 432 Hz is a slightly lower reference, about 32 cents flatter, which some listeners and music communities prefer. Converting only shifts the whole track by that small amount of pitch; the tempo and arrangement are untouched.
Does converting to 432 Hz change the speed of the song?
No. This converter shifts pitch only, so the song plays at the same tempo and length as the original. It is a tuning-reference change, not a slow-down or speed-up.
Can I convert 432 Hz back to 440 Hz or use a custom reference?
Yes. Pick the 432 to 440 Hz direction to reverse the shift, or choose Custom and set any target between 430 and 446 Hz with the slider. The tool shows the resulting shift in cents before you convert.
