 |

Want to do some processing of the mic signal before it goes into the mic
input, but know nothing about the input/output conditions presented. Had no
luck so far in "googling" for technical info about the circuitry related to
the mic input area of a pc. Anyone out there with a clue? |

Hi Steve, your best bet is to use www.google.com ,and |
type in `computer mic input`.
You`ll get plenty to have a read of, there.

It's a line level input conforming to normal audio standards so if what |
you want to do would work with a normal amplifier input, it'll work
with a PC soundcard.

Hi Paul
This is extremely helpful stuff, and I'll be taking a close look. It's a bit
of an over-kill for what I immediately have in mind, though, which is to
take what comes out of the pc speaker output(s), mix it with voice from the
mic, and push the composite back into Windows Sound Recorder via the mic
input. You also sorted out the mystery I found when looking for what pole of
the jack carried the mic bias. I was getting 2.7 volts on both the tip and
ring. Now I see this is for a stereo mic.
Thanks again. Great stuff.

Can you connect the line output to the line input and the mike to the
mike input, and then enable both recording devices in your sound
card's mixer?

Right, typical unpowered mics don't produce line level output.
Soundcard microphone inputs that I've messed with are powered electret
mic inputs.
I would clearly state the objective and ask in
sci.electronics.basics |

Didn't think of it Franc. Been spending a while setting it up. It works, but |
the line input sound level is very low compared with the mic input it's
being mixed with.. I'm wondering if the signal from the speaker output needs
boosting. I'll try this next. |
