It may have been on here or somewhere else, I'm not sure which, but I was pointed to a Youtube video about recording to a PC. In the vid, the author used an Alesis audio interface and said that using the mic input on your sound card was no good -- he didn't say why. I have just tried a bit of recording using the mic input and it seemed ok for such a short experiment. Can anyone tell me why I might want an audio interface (apart from the fact that I wouldn't have to turn upside down trying to find the mic input on the back of my PC). I realise that I can get a USB input and so bypass any failings in the sound card so perhaps that is the reason he didn'y use one in the video.
