Nope. I'm talking about analog to PCM. "Capture" implies wholeness or tracing. This is not what PCM does. There are (because the processing power required to do it is finally, sort of, arriving) people who are working on tracing rather than sampling analog waves. Look into Wave Trace technology.RAM wrote:I think you're really referring to the conversion of .wavs to .mp3s.
At a glance, this seems to address some issues that we haven't gone into here, such as truncation distortion, dither, LSB, etc. (Frankly, my brain is too strained to go much farther. )
Ever heard of super tweeters for the home hifi enthusiast? I don't own one but they are available and do go beyond 20kHz.RAM wrote:it's certainly beyond the range of speakers to move that fast
I should have clarified. We need to keep going higher in order to catch up to analog. The goal with digital video/photography is to have it look as good or better than film. Video tape in either format never quite measured up and pixelation of digital pics requires ever higher and higher resolution rates. But, it's all an attempt to measure up to analog.RAM wrote:Like how you said DVDs replced VHS,we have to keep going for the higher quality.
I guess, here's my end statement. Digital (and science in general) is only as good as the limitations of the tools used to measure things in the natural world and the limited understanding of man at that time. All too often, a breakthrough level of achievement is reached (which is great) and counted as having solved the riddle. And, time and time again, as the measurement tools get better, concessions have to be made that in actuality the riddle had not previously been solved, and "the books" have to be rewritten. All the while, individuals who live in, and perceive and respond to stimuli in the natural world, have in themselves sensed/known what took (and is taking) engineers and scientist time to discover - more so, put nomenclature to. I will err on the side of caution and say that by my own hearing and that of so many others, that digital still isn't quite synonymous with analog whether in regard to amp modeling and/or recorded audio.
Ultimately, I agree with you. For most people, good enough is good enough (which at one time was 8-track)!!! Now, it's ring tones!!! Not me! I'm a die hard.
