- I believe that the favorite piece of music that determined the
- length of the CD was Beethovens 9th Symphony. I think it was
- incredibly short sighted. you could easily have made a 2hr format
- at not much of an increase in cost. (Imagine what CD rom could
- hold if such were true...)
- or in size.
-
- I've been following the thread on CD vs. Analog Quality.
- My post a few messages back generated a few good flames
- via E-mail. I would now like to propose the following hypothesis.
-
- Hypothesis:
- My friend has a very expensive turntable set-up. over $2200.
- He has some fairly recent audiophile pressings, and I have
- been listening to them. (mostly ANALOG masters of course...)
- THis guy is a die-hard Analog freak, and after listening to
- some of his discs, i have to say he has a point. outside of
- Dynamic range, and a little surface noise, There definitely
- seems to be some sort of "fullness" to the music that simply
- isn't present on CDs. My proposition is this: First let me say
- that I'm not all that familiar with digital recording technique,
- dithering, and all that business. I know that in the synthesiszer
- world, the more bits you get (8-16-32) in the sampling, the
- better it sounds.
-
- In CD recording, it is designed to utilize all the bits in a flat
- and equal manner across the bandwith of the freq. response.
- now, our ears are not "flat" by any means. They are much more
- sensitive both to frequency and dynamic changes in the areas
- where speech occurs, and in a "head and sholders curve" around
- that midpoint. Maybe if Digital recording were modified to
- increase precision in a manner following the response curves of
- our ears (i DONT mean boosting the midrange, i mean using more
- bits over those frequencied in more precision, the volume would
- remain unchanged) Perhaps we could unluck the analog "missing
- link" here.
-
- For those rude folks who flamed my opinion that the ear is the
- most sensitive dynamic instrument created, I would like to say
- that i can't name any microphones with a 120+ Db Dynamic range
- at near zero distortion, (notto say the don't exist, I've just
- never encountered any...)
-
- Anyone agree? disagree? (let's keep things polite here, this
- is just a discussion...)
-
- ned.
