"Let's assume a sample rate of 40 K, just to make the numbers work and still get ~20 khz response. Given 16 bits per sample, forget error checking and whatever else comes on a RBCD formatted disk, our stylus would need to vibrate 40,000 * 16 times per second. That's 640,000 cycles per second."
It's not 640,000 cycles per second...... You're mixing bitrate (actually half the Redbook bitrate, roughly) with frequency response.
Heck, if 256 kbps MP3 equated to 128,000 cycles per second, you could argue that MP3 is more-resolute than vinyl.......
"No vinyl fan ever made such a claim for vinyl."
I wouldn't *want* to make a claim like that for vinyl..... Trying to equate bitrate with an analog signal is like trying to nail jello to a wall......
For a long time, the digital advocates **accepted** that vinyl had more resolution- Their argument was that our hearing wasn't capable of resolving the reduced resolution of Redbook CD......
"Lets go the other way. Assume we can track an LP at 40,000 cycles per second, just be an optimistic vinylphile for the moment. Divide that by 16 and we get 2500 words per ~1/2 revolution."
Words? I didn't know Evelyn Wood had "speed listening" courses...... [-;
"That gives vinyl a frequency of max. 1.25 khz when used a digital storage medium - and that's a way optimistic estimate."
Optimistic is right.......
If this is how we do math these days, our education system *is* in trouble......
