Solfeggio Frequencies - Make Solfeggio frequencies DAW-ready

Hey Product Hunt! I built this Solfeggio Frequency Calculator because I kept running into a frustrating disconnect: as a producer, I’d hear about healing frequencies like 528 Hz in wellness circles, but when I tried to actually use them in my DAW, they never aligned with the keyboard. So I set out to bridge that gap. The goal wasn’t just to play a tone, but to give musicians and sound healers a practical way to integrate these frequencies into real music. That meant calculating the exact A4 tuning needed so 528 Hz lands perfectly on a note, generating a full chromatic scale based on that tuning, and exporting a clean, loopable WAV you can drop straight into Ableton or Logic. Along the way, the tool evolved based on real needs. Early users wanted to verify tones with their mic, so I built in a live pitch detector using the YIN algorithm for accuracy. Others asked for DAW-ready audio, so I made sure the WAV exports are phase-coherent—no clicks when looped. It’s all built in the browser with Web Audio API—no installs, no logins. Just a precise, musician-first take on a frequency often treated more mystically than musically. Would love to hear how you’d use it! 🎶
