What is a rain sound generator?
It's a tool that creates realistic rain and thunder sounds using digital audio synthesis. No recordings are needed — the sounds are generated live in your browser for endless, high-quality relaxation.
How can rain sounds improve sleep?
Rain sounds act as natural white noise, masking disruptive background noises and calming the mind. They promote deeper sleep by lowering stress levels and creating a soothing environment.
Are the thunder sounds realistic?
Yes, the thunder is dynamically synthesized using low-frequency oscillators and noise envelopes to mimic distant rumbles or close cracks, depending on settings.
Does this tool work offline?

Can I adjust the storm intensity?
Absolutely! Use the Rain Intensity, Thunder Frequency, and Wind Level sliders to craft anything from a gentle drizzle to a fierce blizzard.
Is it safe to listen for long periods?
Yes, at moderate volumes it's perfectly safe. Many people use rain sounds during work, study, or sleep for hours. Keep the volume comfortable to protect your hearing.
