Sleep Sound Mixer

Clearer sleep sounds.

Choose one coherent scene instead of stacking noisy layers. Add a timer, or let the privacy-safe stillness check fade everything out after quiet inactivity.

Audited sleep mix

Rebuilt around audited recordings and local generated noise. Moodist is used as a candidate library, but only sounds with complete source notes enter the player.

Rain

Heavy Rain Outside a House A steady moderate-to-heavy rainfall recorded outside a house, useful for simple masking without musical layers. Real recording pilot / 5:37

Level

Light Rain, Distant Thunder A peaceful woods recording with light rain and distant thunder, closer to a real place than a generated ambience bed. CC0 real recording / 1:50

Level

Soft Light Rainfall A short, uncluttered light-rain recording for users who prefer gentle rain over storm texture. Real recording pilot / 1:00

Level

Timer fade-out

Stillness sleep check

No microphone, camera, or tracking. If the page is untouched for 20 minutes, HaleHalo treats that as a possible sleep signal and fades out.

16 Moodist candidate files are held back until per-file source notes are confirmed. See audio source notes.

Why the library changed

Sleep audio performs best when it feels like a place rather than a pile of effects. The pilot library now uses real recordings for place-based layers, local generated noise for simple masking, and a stricter audit gate before third-party files enter the player.
