Eight rooms, one ritual









Made for the 9pm desk
The lamp is on. The tea is warm. You have one thing to finish — and for once, you actually want to sit down and do it. That's the feeling these tracks are built around: a steady, warm background your attention can lean against, instead of a silence you have to fight.
Every track is generated to an exact frequency — a true 40 Hz gamma pulse under the music, not a re-encoded YouTube rip. The kind of detail you can't hear on a phone speaker, and absolutely can with headphones on.
€15. Once. Yours forever.
Less than two months of a meditation app subscription — except nothing expires, nothing renews, and it works offline. Download the MP3s, drop them on any device, press play for years.
Honest answers
Will this actually make me focus?
Honestly: it depends on you. Brainwave audio helps many people settle into work; others mostly benefit from the ritual of one steady soundtrack. What we promise is the craft — exact frequencies, calm composition, no ads or interruptions — not a magic switch. Try the previews above; they're the honest demo.
Why not just use free YouTube tracks?
You can — we even recommend trying that first. The kit is for when you want it done properly: verified frequencies, purpose-built lengths (25/50/60-minute work blocks), offline files with no ads, and six distinct moods from deep work to sleep.
Do I need headphones?
Yes, for the 40 Hz layer — binaural beats work by playing a slightly different tone in each ear. The music is lovely on speakers, but the frequency effect needs headphones.
What exactly do I get?
Eight MP3 tracks (192 kbps, ~5.3 hours total, album art embedded) plus a quick-start PDF guide, delivered instantly by Gumroad. Play them on anything — phone, laptop, old iPod, car.
Is this medical?
No. It's a relaxation and focus aid for general wellbeing — not medical advice or treatment. If you have epilepsy or a seizure disorder, check with a doctor before using brainwave-entrainment audio.
