Downstream
Six slow sessions that carry you under, from the old mill's turning water into deep calm.
6th Mind session library
Every session and every Mental 6-pack we make — the most affordable audio-visual entrainment system you can own, and the most advanced one that runs on hardware you already have.
The 36 sessions the app ships with play free right here in your browser, no account needed. Mental 6-packs install to your free 6th Mind account, then play here and on your phone — where every session adds synchronized light, through the camera flash or full-field in headset mode.
Every frequency profile on this page comes out of our own clinical practice, where we record EEG before and after each session and let the data decide what works.

Mental 6-packs
Six sessions built around one theme — winding down at night, sharpening focus, lifting mood — as a complete mini-program. Install a pack and it gets its own section on your home screen, plays offline, and joins your daily routine, so the app gets more varied the more you add.
The free packs are in the app too. The paid ones exist only here: the 6th Mind app never sells you anything, and this page is what keeps it that way.
6th Mind Premium — one subscription unlocks all paid packs. $5.99/mo, or $39.99/yr (two months free)

Three ways to run a session
Every session in this library works at all three levels. The browser is the quickest way to hear one; the app is where light joins the sound.
1
In this browser
A unique combination of isochronic tones and binaural beats, tuned exactly as they are in the app. Free, nothing to install — best with headphones.
Free · no account
2
In the app, with the camera flash
The same audio, now in lock-step with light pulsing through your closed eyelids. Three synchronized entrainment channels instead of one.
Free · no ads
3
In the app, in headset mode
Your phone's screen fills your whole visual field, one half per eye, with the colour tuned to each frequency band. The closest we've come to a professional session at home.
Needs a 3D-printed headset: $10–$30 depending on your local print service
