Music Frequency Converters: Retune Any Song to Solfeggio Pitches
Want to hear a track tuned to 432 Hz, 528 Hz or another Solfeggio frequency? Our free online frequency converters let you retune any song in seconds, right in your browser. Here’s what they do and which ones are available.
What does a frequency converter do?
Standard music is tuned so the note A above middle C (A4) sits at 440 Hz. A frequency converter shifts the entire track so it centres on a different reference pitch — for example 432 Hz or 528 Hz. The melody, rhythm and arrangement stay exactly the same; only the overall pitch moves slightly. It is a quick way to compare how a familiar song sounds at an alternative tuning.
Available frequency converters
You can retune your audio to any of these target frequencies:
- 174 Hz, 285 Hz and 396 Hz
- 417 Hz, 432 Hz and 440 Hz (the standard)
- 528 Hz, 639 Hz and 741 Hz
- 852 Hz and 936 Hz
If you would rather pick an exact target value yourself, the audio frequency changer lets you set a custom frequency instead of a preset.
A note on the claims
Solfeggio frequencies are often linked to relaxation or “healing” benefits. Many people enjoy how these tunings sound, but there is no robust scientific evidence that a particular frequency produces measurable health effects. Treat the converters as a fun, free way to experiment with how your music sounds — and decide for yourself which tuning you prefer.
Frequently asked questions
Which frequency should I choose?
It is a matter of taste. 432 Hz and 528 Hz are the most popular starting points, but you can try any of the presets — or set a custom value with the frequency changer — and keep whichever you like best.
Does retuning change the song's speed?
No. The converter shifts the pitch to the new reference frequency without altering the tempo, so the song plays at its normal speed.
Will I lose audio quality?
The tool retunes the existing recording rather than re-recording it, so there is no meaningful quality loss — any difference you hear is the pitch shift itself.
Do these frequencies have proven health benefits?
No. There is no strong scientific evidence for specific health effects. Enjoy them as alternative tunings rather than as a treatment.
Are the converters free?
Yes. Every frequency converter runs in your browser, free, with no signup and nothing to install.
