Building your own external mic for AudioTool
Hello Julian, we connected some time ago about the sensitivity limits and hardware clipping on devices using your (FANTASTIC) software. I love AudioTool, and use it regularly in installations and Live Venues. All the way out here in Venezuela...
I got curious about building myself a "flat" outboard mike, something good and simple.
I know you can buy them on Ebay, but decided to make my own. Easier way out here...
Since I have a nice Lab here and fix pro and vintage equipment a lot it just so happened that I had the Electret mikes from a little Teac handheld unit that gave up the ghost.
So I started experimenting.
The first thing that parked me is that the MIKE INPUT on that little 4-ring plug phones use is NOT the TIP.
It happens to be the normal GROUND (or sleeve)...!
And the GROUND is the FIRST RING DOWN.
Once I breadboarded this and fiddled awhile, I got everything working perfectly.
I NOW HAVE A LOVELY MINI PLUG-IN MIKE FOR MY NEXUS S.
Works like a charm, and easy to calibrate too.
Just wanted to share this, maybe you can share it with other tinkerers out there...
