ABSTRACT
Most digital cameras can record audio; however, only the higher end cameras will have professional audio inputs, which are XLR plugs in most case. All professional audio is recorded as double system sound, which means there is a separate recorder. Frequently, we record the audio onto a separate recorder but also feed the signal to the camera; this makes it much easier to synchronize the audio to video in post-production. One of the most important aspects of good audio is to not get any extraneous talk or noise that is not part of the scene on the audio recording. The person in charge of audio is the Sound Recordist, also called the Mixer. The equipment on the sound cart can be surprisingly technical and sophisticated at the pro level or might be something as simple as a handheld digital recorder or even an iPhone at the student level.
