Re: [podcasters] Podcasts using these mics?
- True enough. A condensor mic is basically a capacitor, with one plate of
the capacitor (effectively) connected to a plate that catches audio sound
vibrations, which causes that plate to vibrate, which causes a variation
of the capacity between the plates of the condensor -- the space between
the plates varies the overall capacitance.
Add some batteries, and that variable capacitor is varying the fraction of
a substantial voltage available to the output. So from a small-amplitude
input, you're recording a fairly-large-volume, filtered DC output that
reproduces your audio.
But you need the voltage to make that small volume of varying capacity
into a large volume, varying voltage.
