Sound for a visual effect 1.1

 Single vs Double system- When it comes film and video sound, the first thing that is needed, is to determine whether to use a single or double audio recording system. In single system, the audio is captured directly into the camera and records alongside the image. But with double/dual system, sound is captured independently on a digital audio recorder. Double system delivers a stronger audio quality. One of the most prominent benefits of double audio system is that the audio isn't tethered to the camera. This way, you can focus on the image without the sound being jeopardised. 

What is controllable/uncontrollable noise?- Controllable noise is interferences that can be managed. Such as mobile phones, as they can be switched off, so the sound can be avoided/controlled. Uncontrollable noise however, is sounds that can't really be controlled as much. ( for example, a passing car or an airplane)-This is where professional headphones are used. Wait tun till the sound stops, or if it doesn't, move to a different location. 

The different microphone types- One microphone example is the industry standard shotgun microphone.  This microphone can pick up on audio without capturing excess environmental noise. Often, it is mounted to a boom pole where it can be held above or below the person on camera to capture dialogue. (accessories such as a blimp can fit over the microphone to reduce distortion. Another microphone example is the dynamic microphone, this is the microphone that is the most visible microphone that is used a lot of the times in stage productions that feature a lot of singing. This microphone is excellent for recording in loud spaces. The last example is the Lavalier microphone. This style of microphone is used in both film and stage productions as it operates through a wireless system and can be clipped on to articles of clothing. Because of this, these tend to be used if the person on screen/stage is moving around a lot. Because the microphone lacks the frequency balance of the other microphones, it can add unwinder nasal-y sound to there audio. 

Not surprisingly, microphone distance from the audio can make or break a sound recording. Whether using a shotgun or a dynamic microphone, make sure the device is no more than 3 feet/1 meter away from the subject.
