Audio recording techniques
Sound recording for video/film
Using uni-directional microphone and boom pole
Using a Microphone with the Canon XA10
Audio Recording information here > Audio_Mics&SoundRecording
You can use either a shotgun mic or a handheld mic attached to the XLR connections on the camcorder to record much better audio than you would get simply using the camcorder’s internal microphone.
The above images are of a shotgun microphone. One shows the basic microphone and one shows how it is properly attached to the boom pole using a shock mount to hold the mic and with a windscreen covering it. The windscreen, as you may imagine, reduces noise from wind hitting the microphone.
The shotgun mic is uni-directional. This means that it records sound mostly from the front of the mic, and records very little sound from the sides, and almost none from the back. It’s a great mic for recording dialogue.
The shotgun mics we use at CSI require battery power. The batteries are included in the mic kit when you check it out. Mics that require some sort of external power source, such as batteries, are called condenser microphones.
This microphone has a cardiod pick-up pattern. This means that it picks up sound in a somewhat heart shaped pattern, picking up more sound from the front and sides, and less sound from the back.
This is a great mic for recording voices, especially singing.
This mic requires no power source. Mics that do not need batteries or another kind of external power are called dynamic microphones.
The middle image shows a cardiod pick-up pattern (the hand-held mic has this kind of pick-up pattern), and the last image shows a uni-directional pick-up pattern (the shotgun mic has this kind of pick-up pattern).
