BPM Finder Preview

I've been running a weekly quest on ‪@OddonomousSoundz‬ to find the fastest comprehendable beats per minutes. Started off at 500,000 and here we are at 3,125BPM. I'm going up from here just to see what works.
Most notes are only a quarter of a beat so multiply this by 4 if you want to hear the way a band would play it. I just don't see the point in making a beat at a quarter note, it's just confusing my mathematics for the sake of it.
It'd be rare to hear true music on KZbin at these paces. I write the software which genuinely plays the instrument/noise at the right exact moment.
Recorded music, definitely more genuine and better than what I am doing, suffers the issue of recording sound at a timing. So every 1/48000th of a second or more it will record the part of the sine wave at that time. So if you play sound fast it'll eventually not pick up parts of a sound. 3,125BPM is probably okay but when the BPM is in the hundred of thousands it'll likely miss something.
Using software like Audacity will do one of two things when upping the 'Tempo'. Either it will overlap the sound waves and/or become higher pitch. The cheats way is to make it a higher frequency. The faster you play sound the higher pitch it gets.
Not discrediting these other ways. Those artists are far more superior to my music abilities, I'm just playing around.
