About the 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.
- In your browser
- The 36 sessions the app ships with play free right here, no account needed.
- With a free account
- 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.
- Your own
- Build your own in the Session creator, from your music and the frequency you want.
Built on data. Every frequency profile on this page comes out of our own practice office, where we record EEG before and after each session and let the data decide what works.
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
Frequently asked questions
Is the 6th Mind app really free?
Yes, and it stays that way. The 36 default sessions, the 15-day personalised program, headset mode and the free Mental 6-packs are all included, with no ads, no paywall and no upgrade prompts inside the app. The paid packs are sold here in the library instead. That's what funds the app.
What do I need an account for?
Nothing, if you only want to play the 36 default sessions here in your browser. A free 6th Mind account is needed to install a pack, because the account is what carries the pack to your phone and keeps it in sync across your devices.
What do I actually get when I buy a pack?
Six sessions built around one theme, yours permanently. They play right here in the browser, they appear in the 6th Mind app on your phone, they work offline, and they join your daily routine, so the sessions the app picks for you get more varied.
Why can't I see the paid packs in the app?
Because we deliberately kept the app free of anything for sale. Free packs appear both in the app and here; the paid ones exist only in this library. If you never open this page again, the app still gives you everything it offers.
How does a pack get from this page onto my phone?
Install it here with your 6th Mind account and it shows up in the app automatically, in its own section on your home screen. If you're already signed in to the app, you can approve the web login from your phone instead of typing your password.
Should I buy packs one by one, or subscribe?
Buying a pack is a one-time purchase and it's yours forever. 6th Mind Premium ($5.99/month or $39.99/year) unlocks every paid pack for as long as you subscribe, including the ones we add later. If you want more than a couple of packs, the subscription is the cheaper route.
Do I need the headset?
No. Every session works with sound alone in your browser, and with synchronized light from the camera flash in the app. Headset mode is the deepest version of the experience, not a requirement, and the headset is a 3D-printed part that costs $10–$30 from a local print service.
Is audio-visual entrainment safe?
AVE has a broad safety profile: pulsed light through closed eyes and sound through speakers or headphones, with nothing touching the skin and no drugs involved. The one significant contraindication is light-triggered seizures: if you have epilepsy or a history of seizures, talk to your doctor before using any flicker-based stimulation.
Take the library with you
Install the free 6th Mind app to run any of these sessions with synchronized light, offline, as part of a daily routine that adapts to you.
