Well – as a non-techie – I like the idea of just “changing a few wires” – could
that be what the brain is doing in its processing? And can you adapt this
approach to visual processing – filtering/reducing the visual signal in
successive stages, so it becomes an outline, and finally abstract?

Hi all,
I was about to start work on a signal processing project to transform sounds
that are above the range of hearing into like sounds that are within the range
of hearing. This would serve as a hearing aid, but MUCH better because ordinary
hearing aids CAUSE hearing damage by pelting you with amplified sound. The
final product would be something you wear or keep in your shirt pocket, that
adds to sounds that you hear directly with your ears.
So, where could I find a computer that is perfectly adapted to audio frequency
signal processing. OF COURSE, an antique analog computer, where with a few
wires I can change things MUCH faster than you could ever re-engineer signal
processing code. Further, there is no sampling or quantization noise, or other
artifacts of digital implementations.
This computer is a gorgeous piece of antiquity, highlighted by its very retro
Nixie tube voltmeter display.
Technology marches on - but backwards.
Any thoughts?
Steve
