We talk a lot about creating the ultimate video on this blog, but sometimes we neglect to talk about the audio side of things. If our old home movies teach us anything, its that poor audio can ruin a memory. Sometimes it is too soft, sometimes it is way too loud, there can be popping or static…there are just so many problems that can arise. If you want to have the ultimate audio for your next video project, you should learn a little bit about microphones and pic up a few good habits for when you’re recording.
Types of Microphones
(Note: There are more than just these three, but these are the most common.)
Condenser mics use a capacitor circuit to generate electricity from sound waves. They are highly sensitive and can be pretty expensive, but they yield a great sounding product. Condenser mics require a power source, like a battery, in order to work.
These mics already have a permanently charged electret capacitor, so they do not need an outside power source in order for them to function. These are the microphones you find in practically everything, including cell phones, camcorders and headsets.
Note: Works the same as a Condenser. It just already holds a charge.
These are also known as moving-coil microphones. They are very rugged and can handle a lot of noise. They don’t require any special power supply. These are the microphones you typically see used by rock bands and other musicians.
How to Create Ultimate Audio
1. Use the right mic for the right project.
If you have access to a variety of mics, make sure to use them wisely. Use small lapel mics for interviews, bigger mics mounted for shooting scenes with movement and dialogue and stick mics for stand ups.
2. Eliminate bad noise.
Do research to make sure you’re creating the ultimate audio for your video. Do some test runs before you start recording. Is the mic cable working right? Can you hear too much wind? Are your subjects loud enough? Test these things early so you don’t end up with a mess in post production.
3. Always check the batteries.
This seems basic, but if you’re using a wireless mic or a condenser that requires extra power, make sure you always check the batteries or put in fresh ones before you start recording. Also, always make sure to wear headphones throughout the recording process so if a battery does go dead and sound stops recording you will know right away.
