It is proprietary I guess, but I don't really mind talking about it :) I did a talk recently at Northwestern (The Garage) and they were interested, so I spilled the beans. I'd like to get that talk up actually.
I used the Bach's harpsichord concertos - Allegro/Presto/etc, since we're doing focus in that case. It's actually the 2nd most popular theme on the site! I made that one for myself to be honest - I grew up with those things and it was a labor of love, that one. Took some major reconfiguring, but it was worth it I think.
You're definitely not listening to the same thing each time. There's a huge variety. It doesn't generate the sessions in real-time (audio processing of this kind is very, very CPU intensive), but we take the data we get and process it for later use. At this point there's so many sessions "cached" that you get huge variety right off the bat and we're building up an infrastructure to create more sessions faster
I'll be adding more "themes" later. To explain, in some cases there are sessions that use a specific protocol, like the harpsichord one. That's static. But other themes are more flexible, and so different protocols can be used for the same theme. By protocol I mean what we're actually trying to stimulate in the brain.
Some people here have questioned the science behind the claims of focus and relaxation etc, but even without that as a product feature what you're making is pretty awesome.
I can imagine a product where you can combine a bunch of composers and genres and it'll just write songs for you to listen to :)
I'm signing up just to listen to the music your thing makes!
P.S. I played a few Bach pieces while learning Piano, he's one of my favourite composers!
Hey, thanks! I appreciate that. I played classical guitar as a kid - still do. And Bach is definitely a favorite, though one of the most difficult. You just know he composed those lute pieces on his damned organ, where he could use 2 hands and 2 feet ;)
Yeah, I have to say it has not been a great experience here at HN. But, maybe I'll win them over yet. After 13 years, we're finally taking off, and the first thing I did was pour everything in the science, so we'll be there soon.
Well, enjoy Brain.fm! And feel free to drop me a line with an update any time.
What harpsichord concertos did you feed it?
Is every session that is created unique? So you are not listening to the same thing each time?
