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.

Sound Recording
Sound recording and reproduction is the electrical, 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. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by 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 ...

Video
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual 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, 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 broadcast, magnetic tape, optical discs, computer files, and network streaming. History Analog video Video technology was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Video was originally exclusively a live technology. Charles Ginsburg led an Ampex research team developing one of the first practical vi ...

Analog Recording
Analog recording is a technique used for the recording of analog signals which, among many possibilities, allows analog audio for later playback. Analog audio recording began with mechanical systems such as the phonautograph and phonograph. Later, electronic techniques such as wire and 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 sampled and quantized to produce a digital signal which is represented, stored and transmitted as discrete numbers.

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 . 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 inconvenience and generally more expensive media, reel-to-reel systems developed in the early 1940s remained popular ...

Scrubbing (audio)
In digital audio editing, scrubbing is an interaction in which a user drags a cursor or playhead 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 with a similarly varying motion ; Cut-and-paste : the original signal is segmented into frames of constant width and playback is obtained by either discarding (time compression) or repeating (time expansion) some ...
