How to replace mini microphone with more sensitive mic?
I am trying to replace mini microphone (is very similar to mobile phone microphone) of Audio bug with more sensitive Standard electret microphone with intention that it pickup sound from more than 1 metre distance, and in doing so I am getting too much noise in Audio bug out-put.
Do I need pre-amp? Is there any better way to do it? If pre-amp then how to harmonise out put of pre-amp to the input of audio bug?
