Looking it up, 2khz is about C7 (c note at 7th octave), which most music is below, but you'd miss a lot of additional harmonics that could have context.
So, well into the speculative here, if binaural beats are indeed a real thing, e.g. that by offsetting a tone between two ears and frequencies it produces a third epiphenomanal artifact that is not explicitly "heard," but processed outside the range of what the ear can distinguish by the brain, it does imply we could take any sound and then modulate it so that it appeared or was realized in this meta effect range where the brain automatically processes it.
If binaural beats are not real, then there's a lot of speculative woo that automatically gets debunked. But if they are real, and there were a way to take a frequency or sound, and modulate it so that the effect could be processed by the brain as an artifact of its own processing and not as the actual physical "sound," that could be interesting. Maybe the way hearing aids EQ sounds also shifts frequencies and folds them into the range the listener can physically hear already. If there were a meta sound that binaural beats in effect claim to be, there would also be an FFT that would take a given sound input and transform it through stereo headphones to produce it at the frequency one could "hear" as an artifact of the brain reconstructing it.
I'm well into the territory of "dare to be stupid" speculation here, but the premise of creating a binaural beat to create this super-audible artifact, then modulating the artifact effect to transmit the information would be pretty interesting (probably even an ffmpeg one liner). I like cuban cigars and american whiskey if someone reading this becomes a billionare as a result of implementing it, but if it doesn't make a difference, there's a whole subculture of binaural beat internet woo that needs to know it isn't a thing. :)
