"this known neural bottleneck". Do you mean the disparity in the amount of information that the ear sends the brain, at most a few thousand haircells firing ten times per second, compared to the 44100*16 bits per second required for high-fidelity digital audio sound? The same 'known neural bottleneck' occurs in the eyes - about 1000000*3*25 bits per second when your're looking at your computer monitor.
