I'm often asked if I have longer versions of my tracks, in particular for things like studying and sleep. Some of my tracks can simply be looped, but often the isochronic tones begin and end at different frequencies, so looping a standard session is not always ideal.
The best solution is to create a session that has been specifically designed to played over a longer period, and that's what I've done with my new Cognition Enhancer Extended Version.
This is currently just available with the popular Electronic background sound, which I used for the original 30 minute Cognition Enhancer video on YouTube. To give the longer version a bit more variety, it contains an extended mix of the original Electronic track.
