You've probably got another problem - reflections from all over the
lecture
room.

Yes, I hear the echoes, but they are tolerable.


I have heard
that there are high gain microphones out there which are more
sensitive than the kind you might by at Radio Shack, but I have not
been able to find any.

Here are reviews of some representative types of microphone that address
the
problems of recording when the microphone can't be placed close to the
speaker:

Could someone direct me to where I could find such a microphone
designed to be plugged into a computer?

A good professional audio store, particularly one that caters to people
who
work in film and television. Also, stores that cater to people who have
camcorders.

I will check there. Thanks.
