marestudio, Nyquistova frekvencija i ostala prica

[psionic]

Hteo bih jos samo da naglasim da ono gore vazi i za sve digitalne uredjaje koji zvuk obradjuju, ukljucujuci tu i UAD i Powercore i Duende i sva ostala digitalna resenja... Da bi zvuk zaista imao analogni karakter, ni jedna karika u lancu ne bi trebalo da je digitalna (mislim na one delove koji modifikuju i digitalizuju sam zvuk) Kako je danas glavni nosac zvuka CD - postavlja se pitanje svrsishodnosti tolike analogije, mada svakako je najbolje da se digitalizacija nadje na samom kraju lanca...

Večina linkova je nestalo do tih publikacija i ponajviše su dosegljivi preko AES knjižnice.
Imam pdf.-ove ali onda kršim pravila ako bih ih kačio.
Koga zanima več če nekako nači

Malo OT i kao zanimivost:
