4 tools matching “sound”
Tap your keyboard and every key answers with a sound and a burst of animation — a portable audiovisual instrument. Instantly musical even if you can't play a note.
Mix rain, thunder, waves, crackling fire, and café murmur into your own ambient background. Simple sliders, no account, endless calm.
A two-minute test of stillness: ocean sounds, a countdown, and one rule — touch nothing. Move your mouse and the timer resets. Harder than it sounds, weirdly restorative.
Dozens of finely tuned soundscapes — rain, white noise, Gregorian chants, distant thunder — each with sliders to shape the mix to your ears. Built by an acoustics engineer; free, donation-supported.
