La Forge Digital

La Forge Digital is a small online seller in Mouriès, a village in the Alpilles in the south of France. It runs one web store, sacredfrequencygenerator.com, and sells one product: the Sacred Frequency Generator.

The device itself is simple electronics. It's a compact board that produces a clean sine wave, with a keypad to enter the frequency and an LED display to show it. It comes preset to 7.83 Hz, the Schumann resonance, with 432 Hz and 528 Hz stored as quick presets, and you can set anything from 0.01 Hz up to 100 kHz. Output goes through a standard 3.5 mm jack, and two silent coils are included if you'd rather not hear a tone. It runs on 5 V through micro USB, so a phone charger or power bank is enough.

Prices:

• Generator only: $69
• Generator with USB speaker pack: $89
• Two generators: $119

Shipping is free, and there's a 14-day return window.

Buyers mostly use it for meditation, sound sessions and chakra work. The shop is upfront that it's a wellness gadget, not a medical device, and it isn't meant to diagnose or treat anything. That's an honest line to draw, and worth keeping in mind.

If you want to experiment with specific frequencies for music tuning, sound baths or just curiosity, it's a cheaper and more flexible option than buying tuning forks for each one. Hobbyists also use generators like this for testing speakers and audio gear.
