[HAM] why are tonewheels superior?Bohachewsky, Andrew V. abohachewsky at draper.comThu Feb 1 07:57:28 CST 2007
I think Paul's got it exactly right. Ultimately I think the human brain is more capable (perhaps than most realize) of discerning between "reality" and a digital representation of reality. To clarify terms: By "real" I refer to something physical/mechanical which has (by virtue of existing in the real world) infinite bandwidth. A bandwidth limited approximation can come very close (the contribution of the terms out at infinity get smaller and smaller) but never perfect. Mathematically think about switching between time domain and frequency domain and what infinite bandwidth means in terms of time domain. The concept of infinite bandwidth implies that: the paint is NEVER going to come off the brush EXACTLY the same way twice, the piano string is NEVER going to vibrate EXACTLY the same twice. And you will never get EXACTLY the same sound twice depressing a Hammond key - pretty damn close obviously otherwise it would not be much use as a musical instrument but never 100.0000% exact. Any digital representation is trading off bandwidth (increased bandwidth translates to increased cost) - question being how much bandwidth do I need to be "good enough" (anybody remember what JPEG/MPEG stand for?). Limited bandwidth implies repeatability. Which after a while the human brain does find "boring" and... -----Original Message----- the brain quickly loses interest
