Since the data is being encoded with a signal processing trick that is inaudible to human ears this could work in any song with 0-100hz frequencies, right? I was little disappointed when I didn't hear intense dialup-modem-like sounds encoding data I'm the midrange

It's not inaudible. Human hearing extends down to around 20Hz but also some speakers have terrible frequency response down that low so it might mask it better but the tone isn't low enough to be completely inaudible.

Very cool. I suspect there is something unique going on with dubstep "drops" and dopamine release. There is a reason it engages peoples basest systems.

"drops" have their equivalent in every other form of music. Breakdowns in hardcore, choruses in pop music, it's just a catchy part of any tune that people easily grab onto.

Comparing the before and after samples, there is definitely an audible difference for this pair of ears.

To be fair, I listened to the after sample first and it sounded like regular old Skrillex to me.

I scrolled up and listened to the before sample and noticed that the bass was deeper and more harmonious with the higher end frequencies. Basically, the original sample has a "subsonic" vibrations that resonate in time and "harmony" with the higher end sounds. (Also, I'm using higher-end earphones with custom ear canal sleeves to listen.)

So, I probably wouldn't have noticed anything unusual if I'd only listened to the modified bass drop, but I can hear the difference when comparing the two.

Me too(although of course cool nonetheless). For dubstep to fulfill it's "alien communication" meme we need that.

I'm pretty sure that this would drop the volume of the 0-100hz range to half the volume since we dropped the amplitude to 1/2 and shifted. Any sound system with loud subwoofers would be able to detect the difference, but woofer only systems would probably leave the modification mostly undetectable.

It felt very strange reading this, as it was nearly identical to a project I did in college for a class about discrete time signal analysis. We had to decipher encoded messages embedded within Crawling in the Dark by Hoobastank. The sound clip was: "is there something more than what I've been handed?" Funny professor.

I expected it to be similar to typedrummer [1], but with dubstep snippets.
