How do I convert a song to 432 Hz for free?

Drop your audio onto SnipSound's 432 Hz Converter and click Convert to 432 Hz. It pitches the track down by the 432/440 ratio (about 1.8%) to retune it from standard 440 Hz to 432 Hz — entirely in your browser, nothing uploaded.

440 Hz vs 432 Hz

Modern instruments tune to A = 440 Hz. 432 Hz tuning lowers that reference by 8 Hz, which shifts the whole track down by about 1.8%. Whether it sounds "better" is subjective — but converting is easy: SnipSound resamples the audio by the 432/440 ratio so every note lands at its 432-tuned pitch. A 528 Hz preset is included for the "Solfeggio" crowd.

Frequently Asked Questions

How do I convert a song to 432 Hz?▼

Drop your audio in and click Convert to 432 Hz. The tool lowers the pitch by the 432/440 ratio so a track tuned to standard 440 Hz comes out at 432 Hz, then you download it.

Does converting to 432 Hz change the speed?▼

Slightly — this converter retunes by resampling, so the track also slows by about 1.8% (the same ratio as the pitch change). That's how most simple 432 Hz converters work and it keeps the audio natural.

What is 432 Hz tuning?▼

It's an alternative concert pitch where the A above middle C is 432 Hz instead of the modern standard 440 Hz. Some listeners describe it as warmer or more calming. SnipSound just does the retune — we make no health claims.
