Rocking And Rolling

	Rocking And Rolling Rocking and rolling (also rock and roll) is a name for cueing techniques used in sound recording and video recording, particularly in analog recordings. In sound recording, the reels of an open reel tape machine were "rocked and rolled" by turning them back and forth by hand, to cue recordings for playback, and especially for editing, which was done by cutting and splicing the tape. With the passing of reel-to-reel tape recording into obsolescence, the technique is now scarcely used. In video recording, video segments and programs are similarly cued by turning one or more knobs back and forth, on the panel of a recording deck or edit controller, until the desired points are located and set. Analog video on tape is also largely obsolete, although some digital interfaces continue to use cueing knobs, or their virtual equivalents.

picture info	Sound Recording Sound recording and reproduction is the electrical, Mechanical system, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustics, acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Video Video is an Electronics, electronic medium for the recording, copying, playback, broadcasting, and display of moving picture, moving image, visual Media (communication), media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types. Video systems vary in display resolution, Display aspect ratio, aspect ratio, refresh rate, color capabilities, and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcasts, magnetic tape, optical discs, Video file format, computer files, and Streaming media, network streaming. Etymology The word ''video'' comes from the Latin verb ''video,'' meaning to see or ''videre''. And as a noun, "that which is displayed on a (television) screen," History Analog video Video developed from facsimile systems developed in the mid-19th century. Early mecha ...

	Analog Recording Analog recording is a category of techniques used for the recording of analog signals. This enables later playback of the recorded analog audio. Analog audio recording began with mechanical systems such as the phonautograph and phonograph. Later, electronic techniques such as wire recording, wire and tape recorder, tape recording were developed. Analog recording methods store analog signals directly in or on the media. The signal may be stored as a physical texture on a phonograph record, or a fluctuation in the field strength of a magnetic recording. Analog transmission methods use analog signals to distribute audio content. These are in contrast to digital audio where an analog signal is Sampling (signal processing), sampled and Quantization (signal processing), quantized to produce a Digital signal (signal processing), digital signal which is represented, stored and transmitted as discrete numbers.

picture info	Reel-to-reel Tape Recorder Reel-to-reel audio tape recording, also called open-reel recording, is magnetic tape audio recording in which the recording tape is spooled between reels. To prepare for use, the ''supply reel'' (or ''feed reel'') containing the tape is placed on a spindle or hub. The end of the tape is manually pulled from the reel, threaded through mechanical guides and over a tape head assembly, and attached by friction to the hub of the second, initially empty ''takeup reel''. Reel-to-reel systems use tape that is wide, which normally moves at . Domestic consumer machines almost always used or narrower tape and many offered slower speeds such as . All standard tape speeds are derived as a binary submultiple of 30 inches per second. Reel-to-reel preceded the development of the compact cassette with tape wide moving at . By writing the same audio signal across more tape, reel-to-reel systems give much greater fidelity at the cost of much larger tapes. In spite of the relative inconveni ...

	Scrubbing (audio) In digital audio editing, scrubbing is an interaction in which a user drags a cursor or play head across a segment of a waveform to hear it. Scrubbing is a convenient way to quickly navigate an audio file, and is a common feature of modern digital audio workstations and other audio editing software. The term comes from the early days of the recording industry and refers to the process of physically moving tape reels to locate a specific point in the audio track; this gave the engineer the impression that the tape was being scrubbed, or cleaned. Implementations Common scrubbing feedback techniques include: ; Resampling : allows playback at arbitrary rates, which also pitch-shifts the audio, approximating the effect of playing audio from an analog source like tape or vinyl Vinyl may refer to: Chemistry * Polyvinyl chloride (PVC), a particular vinyl polymer * Vinyl cation, a type of carbocation * Vinyl group, a broad class of organic molecules in chemistry * Vinyl polyme ...
