Recording Great Audio

 What are the benefits of using a microphone on a boom vs a lav vs on the camera? What are the differences between single and dual-system recording?

"Good" audio would usually be described as uncompressed, a good sampling rate, good bit depth, is between -20 and -12 decibels, and has a good amount of head room. The benefits of using a boom is that you won't need to worry about the sound of clothes rustling, and your talents can move freely. But, it might not be possible for scenes that have a lot of fast movement, because someone will need to keep up with the talents. The benefits of lavs, are that you don't need someone to hold a boom all the time, and the audio quality can still be good with lavs. Single system recording is when the audio-recording device is plugged directly into the camera. This audio will be automatically synced to the video as you record. The largest downside though, is that you'll need long wires, or have everything close together. Double system recording is when your audio device is plugged into a digital audio recorder, not the camera. This audio has to be synced to the video in post-production, but gives you more freedom with the camera. This is how I'm editing Iron Gun.
