Double-system recording — is a form of sound recording used in motion picture production whereby the sound for a scene is recorded on a machine that is separate from the camera or picture recording apparatus. Double system recording is the standard procedure on motion… … Wikipedia
Double-system sound — PP A technique where production sound is recorded on a separate device to the camera. This can provide more maneuverability for the boom operator and reduce noise, however the audio and video need to be synchronized in post production. Also… … Audio and video glossary
Audio system measurements — are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative… … Wikipedia
Audio equipment testing — is done to provide consumers with an idea of what they are looking for and to make the process of equipment selection easier. The results are published in specialty electronics magazines, online, and in other media. Many people involved in the… … Wikipedia
Double-sideband suppressed-carrier transmission — (DSB SC): transmission in which (a) frequencies produced by amplitude modulation are symmetrically spaced above and below the carrier frequency and (b) the carrier level is reduced to the lowest practical level, ideally completely suppressed. In… … Wikipedia
Double sideband suppressed carrier — (DSBSC) is used for RDS (Radio Data System) because it is difficult to decouple.SpectrumThis is basically an amplitude modulation wave without the carrier therefore reducing power wastage, giving it a 50% efficiency rate.GenerationDSBSC is… … Wikipedia

Audio tape length and thickness — Since the widespread adoption of reel to reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats. This article describes the length, tape thickness and playing times of some of the most common… … Wikipedia
Double buffering — In computer science, double buffering (or ping pong buffering) is a widely used technique for minimizing the delay (flicker) in input/output operations which use a buffer. Single buffering is affected by buffer underrun and buffer overflow.… … Wikipedia
