Timeless prose. Scientifically enhanced. Classic literature layered with delta-wave binaural beats, solfeggio frequencies, and immersive ambient soundscapes — calibrated for the deepest possible rest.
Three layers of sleep science
Rain, ocean waves, forest night, fireplace — 13 immersive environments layered beneath the narration to mask distractions and create a cocoon of calm.
10 healing frequencies from 174 to 963 Hz, played as gentle sine waves beneath the narration. Each frequency maps to a different aspect of relaxation and renewal.
Delta wave frequencies at 0.5–4 Hz guide your brain toward the deepest stages of sleep. Different tones in each ear create a third, entraining frequency. Headphones recommended.

Frequently asked
Solfeggio frequencies are specific tones (174–963 Hz) believed to promote healing and relaxation. Each frequency corresponds to different benefits — 528 Hz is associated with stress reduction, while 432 Hz is known as the natural tuning frequency. Our player layers these tones beneath the narration at a gentle volume.
Binaural beats play slightly different frequencies in each ear, creating a perceived third tone that guides your brainwaves. Our delta wave presets (0.5–4 Hz) encourage slow brainwave patterns associated with deep, restorative sleep. Headphones provide the best experience.
Headphones are recommended for the full binaural beats effect, since the technology relies on delivering different frequencies to each ear. The solfeggio frequencies and ambient sounds work beautifully on speakers too.
Yes. Every audiobook is a public domain work, free to listen to on YouTube. The solfeggio frequencies, binaural beats, and ambient sounds are all included at no cost. No paywalls, no trials, no accounts required.
Older prose has a natural, flowing cadence that’s perfect for drifting off. Combined with solfeggio frequencies and binaural beats, classic literature creates ideal conditions for deep sleep. Plus, public domain works mean we can offer everything for free.
