Hello,
I am using Adobe Audition and Creative Audigy to do some guitar and keyboard recording in Audition, but they keep coming out with a lot of noise. I'm going from my guitar amp output to my audigy front input, I do the same routing for the keyboard. Anyone have any ideas of how to fix the noise?

anyway to input from the guitar to PC ? alot more direct and less interfering

You are putting an already amplified line into your PC. Bad idea!

Go from source to PC. THEN amplify as needed.

So i need to go from the guitar directly to the audigy card. How do I amplify it through windows? Also, how can I do this with the keyboard?

With the guitar, you can just get a 1/4 jack converter to make it fit your computer input, but then you will get some lag when playing. Buy it from Radioshack for about $3 - $5
