Rain & Hum

Long, non-stop sound for sleep and focus — brown noise, pink noise, white noise
and clean tones, in three-hour and full-night sessions with no talking and no
interruptions.

Every track here is synthesised from scratch in the frequency domain, not
recorded or sampled. That means no compression artefacts, no hidden loop seam,
no third-party audio, and a spectrum that is exactly what it claims to be — the
curve on each thumbnail is that file's real measurement.

Sessions run non-stop: no fade, no break, full level from the first second to
the last.

What you'll find:
• 3-hour sessions — brown, pink, white, blue, violet
• 10-hour full-night editions for sleeping straight through
• Black-screen versions for dark rooms and OLED phones
• Pure tones — 40 Hz gamma, 432 Hz, 528 Hz, honestly labelled

Rain and other ambiance are on the way — that's the other half of the name.

No health claims. No AI-generated audio. Just a clean signal.

New sessions weekly.
