a really interesting video on sound and the brain

Anna had this video by Vi Hart dropped in as a comment on one of her Facebook posts, and it’s really cool. It’s called What is up with Noises? (The Science and Mathematics of Sound, Frequency, and Pitch) and she’s talking about brains and harmonics and how sound is processed.

When she gets to the harmonics part and brain fill-ins, she’s talking about things which I figured out only last year, and started using with the bass parts on Bone Walker, so that you could hear them on things like laptop speakers.

Or, more accurately, think you’re hearing them.

(Things like this are why I need to remix Dick Tracy Must Die.)
