re : irq?

it is a hardware interrupt... think of it as a direct route to a piece of hardware in your computer, important things that must constantly transmit or recive data (sound card,mouse,video,hard drives,ect...) ,all this data is being moved around on 1 bus or (the main highway to the cpu),if all your cards/devices can access it they need a way to do it one at a time. the irq gives adresses to each device ,example: mouse irq 1, hdd controler irq 2, sound card irq 3, and so on. the main reason so everything is orderly and can have it's go at getting it's job done. now more than one device can share an irq (this is where the fun starts). i belive their are 15 or 16 irq's that can giving out to different pieces of hardware. (what u say? what if u have more hardware than irq's ) if their is a need for more interrups then you must share! (so we've gotten this far ,now you know an irq is just a steering wheel for data. )

here's the problem when your building a audio work station ,how many hands on the wheel before you crash?

one of your goal's should be if you want to make/edit/record music on a computer and you want pro results ( hey who don't? ) is to keep those irq's under control. ( how u say? )

the home audio workstation
( here's my idea of a good setup perfect for audio )
let's start off with the proccesor u want fast but it don't have to be the latest greatest my recomendation would be the slot-a athlon at 1ghz, compared to pentiums their better ,cheaper, faster given the same task even than the new pentium 4's.
next is memory i say start with 384 megs ,i'm going to move to 512 myself, when u got 64 tracks of audio to be edited u be happy u got it then. (get the fastest memory u can right now pc-133, $120 for 256 meg not bad! i don't recomend ddr ram as it is too new and the bugs are not worked out yet.)

next hard drives i assume the motherboard has ultra dma controlers on board, u want ata-66 ,2 ata-66 hard dirves 7200rpm with at least 2 meg buffers and 9ms seek time. (from what i have seen so far ata-100 make's no diffeance as eide drives are not fast enough to use the extra speed.)
next a video card, your pick on that one but i want to play games and want no card conflicts ,so we go with a 32meg nvida on the agp slot.
next modem ,don't use one (remember this is an audio worksation not grandma's aol computer! ,plus if u really need one buy a usb modem that u can remove ,we can't tie up those irq's on modems when making that muti-platnium cd :-)
next sound cards ,what ever u like ,not using our pci slots for other things we should have around 5 of them, more than enough. when u buy cards u want first and formost is compatability for any future plans. (i myself want 2 analog in/out 16 digital in/out 2 midi port).
software once agian is a personal thing, what u like, but don't get trapped into buying a package that requires the same brand of card or needs specific hardware, look for somthing that supports mutiple cards and takes plug in's.
all together this can be had for less than $2000 if u know what your doing, hope it helped.

dam this is long...
