Convert Music to 417Hz Online — Free Frequency Converter
This free online tool re-tunes your music from the standard 440Hz pitch to 417Hz, one of the solfeggio frequencies, letting you explore how your favourite tracks sound at this alternative tuning without any software to install.
What is 417Hz?
417Hz is one of the so-called solfeggio frequencies, a set of tones referenced in certain spiritual and alternative-wellness traditions. Standard modern music is tuned to 440Hz (concert pitch, ISO 16), meaning the note A4 vibrates at 440 cycles per second. Re-tuning to 417Hz lowers the overall pitch of a recording by roughly 38 cents — just under half a semitone — giving it a noticeably warmer, slightly darker quality.
Claims that 417Hz promotes healing, facilitates change, or carries transcendental properties are anecdotal and not supported by scientific evidence. The audible difference is real; any perceived wellbeing effect is subjective and should not be taken as a health claim.
Why convert music to 417Hz?
- Sound exploration: hear how familiar recordings feel at a different fundamental tuning.
- Meditation and relaxation content: creators producing ambient or mindfulness audio sometimes prefer alternative solfeggio tunings as an aesthetic choice.
- Comparison with other solfeggio tones: 417Hz sits between 396Hz and 432Hz, making it easy to A/B test different tunings on the same source file.
- Personal preference: some listeners simply find the slightly lower pitch more pleasing or easier to listen to for extended periods.

Yes, the tool is completely free. No account, subscription, or payment is required. Simply upload your file, convert, and download.

Your file is processed on the server solely to perform the frequency conversion and is then deleted automatically. It is not stored, shared, or used for any other purpose.
Does re-tuning to 417Hz change the tempo of my music?
No. The converter shifts the pitch of the audio without altering its playback speed, so the duration and rhythm of your track remain exactly the same.
Is there a scientific basis for the health benefits of 417Hz?
No. Claims about solfeggio frequencies improving wellbeing or having healing properties are anecdotal and not supported by peer-reviewed scientific research. The tool simply re-tunes your audio as an audio processing operation.
Which output format will I get after conversion?
By default the output format matches your uploaded file. You can also select a different audio format before starting the conversion if you need to change it.
