Sound recording and reproduction :

Sound recording and reproduction is the electrical or mechanical inscription and re-creation of sound waves, usually used for the voice or for music.
The two main classes of sound recording technology are analog recording and digital recording.

Film format :

A film format is a technical definition of a set of standard characteristics regarding the image capture of still film or the image capture and projection of motion picture film. In the latter case, it may also encompass audio parameters (though often not). These characteristics usually include the film gauge, pulldown method, lens anamorphosis (or lack thereof), and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ.

Telecine:

Telecine (IPA pronunciation: ['t?l??s?ni, ?t?l?'s?ni]) is the process of transferring motion picture film into electronic form, or the machine used in this process. Telecine enables a motion picture, captured originally on film, to be viewed with standard video equipment, such as televisions, video cassette decks or computers. This allows producers and distributors working in film to release their products on video and allows producers to use video production equipment to complete their film projects.
