[QUOTE="Marcusb, post: 182646, member: 11550"] yep, I have a mic under my TV. It works well for the most part, except when there is audio playing from the TV. Then it becomes "difficult". The mic is a relatively cheap desk top one. It's the best I could find without going to more pro grades. I think I said a lot earlier in this thread that my idea for background noise cancelling is that it should be done in hardware. shouldn't be too hard with an operational amplifier and they start at about a dollar. An Operational amplifier has a postive and a negative input pin. You connect the negative to the PC audio out and the positive to the mic and the output of the opamp to the PC mic input and the PC will only see the mic inout minus the TV output. Of course there would need to be a bit of work done to balance this, as the levels have to match. Maybe some automatic gain control. It's never as easy as it firts sounds, hey? I'm just never home enough to try this out myself. hey, for anohter one of my silly but "what if" ideas is that the response for things like date etc are hard coded. Could we have variables for this instead? you know, the usual <dddd> = day of week, <yyyy> equals year type of thing. [/QUOTE]
