Carnegie Mellon Scientists Show How Brain Processes Sound

This work at CMU looks interesting and potentially significant.

First, there's biomimicry angle. The most amazing machines on this planet are biological machines, and I am fascinated with each discovery on this front. Additionally, there are issues of interest in the areas such as digital signal processing and machine learning.

"Until now, scientists and engineers have relied on Fourier transformations—initially discovered 200 years ago—to separate and reconstitute parameters like frequency and intensity as part of traditional sound signal processing.

'Our new signal processing framework appears far more efficient, effective and concise in conveying a rich variety of natural sounds than anything else,' Lewicki said."
