Well...... A good place to start would be to consider which aspects of
the op-amp performance are important to you.
Did you notice 'carbon mic'?

I did but was planning to consider those aspects of his requirement later. In
fact I was also going to discuss the alternative use of electret capsules since
carbon mics are no longer used AFAIK.

Which reminds me...
Does anyone do 'optical' microphones, where the movement of a mirror etc
is measured by bouncing light off it or fringe counting in an
interferometer?
