Hi-Z) and have an amplifier (called a preamp in this case) on it in order to bring the signal up to line level (before it hits the ADC). But I agree that is what the OP wants, assuming the computers in question will have mic inputs (I think most motherboards have them integrated these days). _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
