Now, I am by no means any kind of expert on audio. But I do have a basic understanding of how it works. So if what I say is just utterly retarded, please forgive me ^_^;;
Now, high end audio sample rate is around 96 khz, or 96000 samples per second. Now, what if there was some way to record audio at 1 mhz (or roughly 1 sample per nanosecond). First off, you'd have an obsenely large file on your hands. Most modern equipment probably couldnt write the data that fast anyway, but for the sake of theory, lets say it can. Now, if you were to stretch out that waveform, and essentially make it equivalent to around 44 khz, what kind of things do you think you'd be able to hear? Things that are simply too fast for our ears to pick up? Or maybe, sound waves dont even move that fast, and being able to record at that speed would be useless anyway.
Or maybe you'd hear ghosts........ woooooo......
Anyways. Just some silly theorizing on my part. Don't mind me!
