Microphone/sound card question

[John Dunkley]

I want to use the 'stereo' line-in of my sound card as two microphone
inputs, one microphone in each channel (left and right.)

If I construct a simple amplifier to boost the microphone level to 'line
in' level, is any compensation required or is a straight amplification OK?

I want two separate microphones to produce two independent tracks in my
software program and using one sound card will allow this if I use the
'line in' line rather than purchase two sound cards to get two
microphone inputs into my software.

Hasnt the sound card got a stereo mic in socket ? Most do.

Whether it requires compensation with the
line in socket varys with the mics used.

You could use what is basically just a passive Y adapter to
the mic input of the sound card if it has one. Basically just
connecting two mono mics to each side of the stereo mic in.

Might get a bit tricky with what are often called
powered mics tho, and quite a few of the cheap
mics are. You'd just have to allow for that too.

John,

I understand that the consumer sound cards mostly have mono microphone
inputs, but the following link may be of help.
