What Is 432 Hz Tuning?
Standard tuning sets A4 to 440 Hz — the international reference pitch adopted in 1955 (ISO 16). In 432 Hz tuning, A4 is set 8 Hz lower, and all other notes shift down proportionally. This alternative tuning has been popular among meditation practitioners, yoga instructors, and some classical musicians for over a century — Verdi himself advocated for a lower reference pitch.
Whether you prefer 432 Hz for its sound, for meditation, or simply out of curiosity, this tool lets you convert any audio to 432 Hz tuning directly in your browser. For manual pitch adjustment by semitones, use our Pitch Shifter.
How to Convert Audio to 432 Hz
- Upload your audio — drop an MP3, WAV, OGG, FLAC, or M4A file (up to 50 MB).
- Choose your target frequency — pick 432 Hz (standard), 528 Hz ("love frequency"), or set a custom frequency.
- Preview and export — listen to the converted version, then export as a 320 kbps MP3.
432 Hz vs 440 Hz: What's the Difference?
Converting from 440 Hz to 432 Hz shifts every note down by about 0.32 semitones. All notes move proportionally — it's a logarithmic scale, so the shift isn't a flat 8 Hz subtracted from every frequency. The difference is subtle in isolation but noticeable when you compare the two versions side by side.
Some listeners describe 432 Hz as warmer and more natural. Others hear no difference. The best way to decide is to try it yourself — upload a track and listen.
What Is 528 Hz?
528 Hz is known as the "Love Frequency" or "Miracle Tone" — one of the Solfeggio frequencies popular in sound healing and meditation. Converting 440 Hz audio to 528 Hz shifts pitch up by about 3.16 semitones. Our 528 Hz preset makes this conversion one click.

Frequently Asked Questions
What does converting to 432 Hz actually do?
It shifts the pitch of every note in the audio down by approximately 0.32 semitones. The speed and duration stay exactly the same. A4 moves from 440 Hz to 432 Hz, and all other notes shift proportionally — it's a logarithmic scale.
Is 432 Hz better than 440 Hz?
That's debated. Some listeners and musicians prefer 432 Hz, describing it as warmer or more relaxing. There's no scientific consensus on health benefits. We recommend trying both and going with what sounds better to you.
Does this change the speed of my audio?
No. We use a pitch-shifting algorithm that adjusts frequency without affecting speed or duration. Your track stays the same length.
What is 528 Hz?
528 Hz is called the "Love Frequency" or "Miracle Tone," one of the Solfeggio frequencies popular in sound healing and meditation. Converting 440 Hz audio to 528 Hz shifts pitch up by about 3.16 semitones.
Can I convert to any frequency?
Yes. Use the Custom mode to set any source (420–460 Hz) and target (400–560 Hz) frequency. The tool calculates the exact pitch shift automatically.
What audio formats are supported?
MP3, WAV, OGG, FLAC, M4A, AAC, and WebM. The output is always a 320 kbps MP3 file.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using the Web Audio API. Your files never leave your device.
How good is the audio processing quality?
We use the same techniques found in professional audio software: convolution reverb with real impulse responses, phase vocoder time-stretching, HRTF-based spatial audio, EBU R128 peak limiting, and LUFS loudness normalization. What you hear in the preview is exactly what you get in the export — we guarantee preview/export parity across every tool.
