So im getting a computer custom built for around $1200 and i want to record my music on it and i dont know what i should have in the computer. Like ill probably have a good sound card.But and will i need an adapter to plug into the microphone plug in, or can i get something that i can plug my guitar (or cable from my amp) right into without losing any sound quality.. So what ,if any special parts should i have in this computer for basic recording thanks guys
Your best bet is to get a mixing board and get an ADC and DAC convertor and plug it in via firewire. Get a good DAW too, I use Pro Tools but that's a little advanced.
for recording guitar you should get something like Amplitube and a stealth plug
I use the usb-out of my Podxt, guitar to my macbook, record in Garageband, then mix in Ableton Live! 6. I get pretty good quality too, but yeah, Protools is king.
