Are you using an onboard mic on a laptop or an external mic plugged in?
I'm using an external mike. It seems when I use the mike to do a voiceover for my radio show, a glitch appears, when I play it back. Someone I know showed me how to run the speaker system through my mike, but I want to use the sound card in the computer. How can I use my sound card without the glitches appearing in my voiceovers?
