If you are talking about editing audio files already on a PC, you don't need a soundcard. If you mean that you need to record some audio however, most consumer soundcards do very poorly in this area (both in terms of inputs and quality). A brand like M-Audio would be more suited for your needs in that case.
Thanks for your input!
Would an M-audio card like the one I mentioned above suffice for beginner needs?
Does it provide descent output to listen to music? Again not for 3D gaming needs. Just for music listening and working on Audio inputs.
