Howdy Nithin,
I used a microphone pre-amp to get a 1 Volt 20 mA drive for
an experiment long ago. Check the specs on the audio input
and compare that to your mic signal output. I would think
that either a direct connection will work or use of a pre-amp
will make the direct plug in very easy.
Patience, persistence, truth,
Dr. mike

samples. The algorithm is working fine and I have tested it.

have a Mike from "Zebronic", which I will connect to "LINE In" port of the board
by the Audio Connector. The "LINE IN" port of the board does not provide power
to the mike, so I am connecting the Mike Output parallelly to the "Mic" port in
the PC which provides the power to the mike.

Mike and Audio signal from the mike is sent via a "Audio Connector" to the "
LINE IN" port of the Board. I will record the Audio samples and play it from
the "LINE OUT" port of the board.
