- I think you ment 22KHz which would be the Nyquist rate for sampling
- at 44KHz. One might argue that the Nyquist rate only assures frequence
- not wave shape so that a 20KHz cut off would not distinguish a 12KHz sine
- wave from a 12KHz sawtooth, and that human hearing might not be strictly
- frequence response bassed, but I will not since my real purpose here is
- to shamlesly slide into a commercial announcement: for all those analog
- lovers, I have a fantastic 10 year old SOTA Saphire tunrtable (Grace arm,
- and Vanderstien head amp) that I would love to sell so I can buy more CDs!!
- call me.
