A couple of times a year I have a telephone consultation that I record and transcribe for both of us (with the permission of the other person). Over the years I have used a couple of different pickups/recorders but while both recorded me just fine they were weak recording the other person. When I try to transcribe the conversation it's difficult to hear the other person.
So I was wondering whether there are any inexpensive alternatives. I looked at some better equipment, but it looks like several hundred dollars to do it right (tape machines with AGC). Since all I need is the pickup (or direct connection) and a smart amplifier (not the recorder) I was thinking under $50 would be nice.
So if anyone knows a source for (inexpensive) existing equipment or a circuit for something that would actually work I would really appreciate it. Remember you're talking to a software guy here, so talk real slow.
