There are lots of opinions about the right kind of mic for podcasting. In this post I want to cover some of the secondary factors that should go into selecting a mic.
NOTE: I will make some generalizations for the sake of space and this post is based on my own experience and opinions. Your mileage may vary.
1) Power
Dynamic mics (like my favorite the Heil PR-40) don't require an external power supply. If you select one of the popular condenser mics, you will either need an on-board battery, phantom power supply or a mic pre-amp. This is typically no problem in a studio but might be more challenging in the field.
2) Environmental
Will you be using your mic in a very damp, humid or hot environment? You should know that most condenser mics will have more trouble in these environments than dynamic mics. Condenser mics have polarization problems in these conditions. This is what causes a crackling sound in some mics.
3) Size
If you need to use a mic in both a field and studio setting, size may be a factor to consider. Large mics don't tend to travel as well as small mics. And if you have to interview people who are not used to being in front of a microphone, they may be intimidated by a large mic.
4) Response Curve
Do you want a mic with a flat or tailored response curve? Flat response curves provide a natural, uncolored sound. Mics with flat response curves are usually good multipurpose mics.
If you get a mic with a tailored response curve, the right mic can improve vocal presence.
I am not making any specific mic recommendations in this post. That's impossible to do without knowing more about who uses the mic and how they use it. I am suggesting that you consider these factors before you decide which mic will best suit your needs.
