We are going to be recording software tutorials and so it will be voice only. The problem is that the pc's being used to record are small form factor with limited ability to add a sound card. So this brings us to the question, for voice recording is the internal sound card good enough or would a external USB type sound card worth looking into? Our type internal sound cards are: Internal Sound card #1 Analog Devices ADI 198x Integrated Audio Internal Sound card #2 Analog Devices ADI 198x Integrated HD Audio Is it worth it to get a USB type external sound card vs. uysing the internal Intel sound card? What are some good USB mics for voice recording that are under $100.00 Thanks for any suggestions!!
