i've recently been researching the ins and outs of home recording as it looks like i'm taking over the role of 'engineer' for my little band in a box (read people that show up in my basement to play). there are a lot of threads on pc hardware, which do me no good because i've been working in computer hardware for 10 years now. that part is safe. there are also a lot of threads on which soundcards people prefer for their DAWs, including echo, m-audio, and so on. these also do me no good because they never actually explain what high end soundcards do. in other words, i'd like to know about high-end DAW recording soundcards the way i know about regular pc hardware. what do they do, why do they do it, what can i accomplish with them that i can't with a regular soundcard (keeping in mind i'm not about to go out and purchase a regular one, not even the sb audigy). even resources or reference material on how i use them, what they offer me, and what i can accomplish with all their advance features and so on). all i know now is "high end soundcard = high end home recording". it's very dreamy, but also leaves me in the fog. i'm hoping this turns into a question and answer thread because i've never seen an informative post on true DAW soundcards to date in all my fruitless searching. please help me.
