Entries found for search: encoding

encoding : (1) The process of converting the already sampled, numerical voltage of the analog input into binary numbers and assembling these with any location and error-related data generated elsewhere into complete digital words, usually of 16 bits. See analog-to-digital converter. (2) The application of any type of processing to a signal before recording which will later be removed by complementary processing during playback. Most NR systems are good examples of the encoding/decoding process. See stretched.

free encoding : An extension of spaced microphone recording techniques, systems which create pseudo-stereo from a mono source will also generate a strong surround signal, and stereo-width controls can be used to manage the balance between frontal and surround channels. Increasing stereo width also increases the level of the surround channel, whereas decreasing width reduces the surround content. This is because a surround decoder will automatically send anything which is of a similar level, but opposite polarity between left and right channels, straight to the surround output. Artificial reverberation, for example, is automatically spread across L, S, and R. See LCRS.

Scheiber matrix encoding/decod : The algorithm used in Dolby Stereo optical process to produce quadraphonic LCRS(left/center/right/surround) sound from two channels. In this process, common in-phase information would bleed into the center channel, while the surround channel would receive out-of-phase material. See SVA.

DP5xx encoding : A family (DP521/DP522/DP523/DP524) of 2-channel codecs used for point-to-point and point-to-multipoint signal distribution: ISDN, Switched-56, T1 or DS-3 networks; recording/post-production studio interconnection with or without video; and voice-over and other applications. AC-2 and AC-3 perceptual coding algorithms are supported to provide audio transfers at a total data rate between 56 kBps and 384 kBps. With AC-3, single-channel, two-channel, and composite stereo algorithms are supported.
