Hi. I have an old @$$ labtec am-242 mic. It is just a desktop "stick" mike. I hooked it up to my computer and it works. I can record and play back and everything. But I want to increase its sensitivity.

I *think* I may have done this, but I can't really tell a difference. I am running Vista btw. I went into Sound, went to my mic under "recording" and selected the mic, then hit properties. Then I went to levels and turned up the boost all the way to 30dB. Did this increase the sensitivity? I can't really tell the difference. Are there any freeware apps that can increase the sensitivity, that you would recommend?

Also, is there anything helpful you can tell me about wireless mics? Do they even have them? I know they have wireless cameras, but I am looking for wireless mikes for my PC. The smaller the better. How would I configure multiple mics to work on the computer with only one input jack? How would these things be configured to save the file? Would each of the mics save to its own file on the PC? What frequency would they transmit on? Probably 2.4Ghz...in that case, I would have to switch to a 5.8Ghz phone.

Thanks guys. I apologize if this is not the right forum for my questions. Pretty sure it is though.

To save multiple tracks you would need an input device that has multiple inputs. There are audio cards that can input 8 or more channels. Wireless mikes are probably in the 100 MHz range. Models are available with 20 or more channels. You would need a receiver for each. It is possible to record more than 24 channels
at once depending on your hardware.

Thanks for the great information. Any advice as to how I may boost the sensitivity of recording devices?

The easiest way to boost the signal is a preamplifier. You will have to match the type of microphone with the amplifier. Computer type microphones are frequently of the electret type and have a built in amplifier.
