Microphone to PIC

[scaenix]

above 15khz make sure of your mic spectrum specs before. forget the speaker.

i don't quite understand why i should "make sure of my mic spectrum before". before what? I'll use a tweeter instead of mic if i have to..

speaker/tweeter are good to reproduce sound, but i doubt of their reliability/efficiency as microphone. Worth a try for sure.

what would likely be better to use for the circuit? condenser or dynamic? can you suggest any easy method of determining the leg configuration of a 3 wire condenser mic? Thanks in advance.

any model for this mic? is this a professionnal XLR connector or just a 3 wire capsule?

Any picture or part # would be handy.

Condenser or dynamic? Who knows, the best way will be to evaluate them with a pink noise and a spectrum analyser.

Few days ago i found the following freeware for someone here. I've tried it, and i'm really impressed how good it is... for a freeware.

It's just a simple 3 wire capsule.

I am feeding the mic into an amplifier which will turn the signal into pulses. I want to measure the pulse width and compare the widths of the two mic inputs. The problem is I do not know what commands to use in the PBP program. I've read the manual and PULSIN seems to be a good command. I reallt need some hints on this. Thanks again very much for helping me even until this far.

You could use Count as well. To me using the internal Timer/Counter have it's advantages.
