Sure.
I'm not recording digitally though. Only analog right now.
I'm currently using:
p4 3.0 ghz, 800 mhz fsp
1 gig dual ddr pc3200 ram
I have 2 soundcards in my computer. The one I use for recording is an
Echo Darla (
http://www.echo-audio.com) The model I have was discontinued but it works very nice. Echo makes excellent soundcard. It has 2 1/4" input jacks and 6 1/4" output jacks. (for different monitoring capabilities)
The second soundcard is a Soundblaster Audigy 2. I primarily use that for gaming.
I use to have a MOTU 1248 soundcard.. That thing was a freakin MONSTER! Stupid me when I first started pc audio recording didn't know what I was doing so I took it back. It has 10 gold plated 1/4" input jacks.. well all kinds of crap. hehe.
I mostly record guitar and keyboard. I have a Line 6 Pod Pro plugged into a mackie mixer, which is plugged directly to my soundcard. For the keyboard, I have the keyboard plugged into a Roland JV-1010 midi synth, which is plugged into a midisport midiman (midi->usb converter box).. which is plugged into my pc via usb.
I've heard alot of good things about the Delta 66. I've never used one though.
My Echo soundcard doesn't have digital inputs, just analog. Their better soundcards have digital functionality though.
I would suggest checking out the Echo Layla also (I think that's the one) It appears to be an excellent soundcard.
My hard drive is just a standard Western Digital, 8 mb catch, 7200 rpm hard drive. It works fine. I've never recorded from more than 1 source before with it though. But I'm guessing it will hold up on more than 1 source at a time.
I don't hear people talking much about using a RAID setup for recording. But that might be something worth looking into if you're going to be recording multiple things at the same time. Just a guess.
My old pc, which I used for recording for about 2 or 3 years was a p4 1.4 ghz. It had 500 mb of ram. Only a 4 mb catch 7200 rpm hard drive and it ran fine. I never had any problems with audio recording or playing out of sync or anything.
Well, I hope this helps. Just make sure you stay away from soundblaster soundcards. I've read that they 'cheat'. Most say they record in 24 bit, but I've read that they actually record in 16 bit then upsample the audio. I can't confirm if it's true or not though.
Good luck.
