# FrequencyGenerator.com

> A free online tone generator for healing frequencies, meditation, and sleep. Generate 432 Hz, 528 Hz, Solfeggio, and chakra frequencies as pure sine tones; layer them with white/pink/brown noise, binaural beats, and a subharmonic tone; and use "Sleep Mode" (Bake for Sleep) to optimize a mix for long background playback — using less battery and keeping it playing in the background with the phone's screen locked. Runs entirely in the browser — free, no account, no download.
