Hi, i hope some of you audio lovers will give ma an answer to few questions. First i have to mention that i'm reading a lot about it from this site and other's but don't have a straight clean answer to few things.
1. The digital signal coded in 01 system (binar) gives a more square soundwave, but when its coming from dac it is normalized to smooth linear wave yes ? So if it happens, the dension of sample rate and bit depth will determine how precise it will be transformed into linear wave due to original analog wave.
But the Nyquist theory about half of sample rate determines that if we want the highest audible frequency we need about 40 000 hz to hear 20 000 hz. Am i thinkig good that it's beacause of that transformation into digital code and that high frequencies are faster, so they need higher sampling rate to catch more curve angle ? So if 44.1 khz gives as enough dense sampling to reproduce good sound, what will higher sampling rates give ? We don't hear more than 20 000, so what's up with it ? Is the lost of the non audible for human frequencies will change the reproduction of analog signal from digital and distort, change the 0-20 000 frequencies ?
2. The bit depth give's us even more dense code to transform into analog, so more precise. But if it gives better dynamic range (higher in db) what does it mean ? If we have higher dynamic range it will play more maximum and minimum decybel sounds or it will just reproduce the same sounds, frequencies but they will more vary in loudness. I mean for example the sound of 1 db and 96 db with better dynamic range will be now 1db and 100db.
3. Is neutral sound described also as flat of frequencies is more realistic due to original recording ?
About vinyls, does the vinyl record have linear waves or is it also changed in some way as digital ? If not, it should have more realistic reproduce.
