Now looking at definitions starting with letter "w"

wild sound/wild track : A film soundtrack recorded for motion picture where the audio elements are not recorded synchronously with the picture. Wild tracks are frequently used to get a clean recording of dialog that was otherwise unobtainable because of noise on the set. The opposite of sync sound. See also scoring wild.

window : (12) The frequency band in which a device is operational, e.g., the passband of a bandpass filter. (2) Short for timecodetimecode window.

window dub : See BITC.

windshield/windscreen : See pop filter.

wiper : The movable contact in a pot is called the wiper, or sometimes, the arm.

wireless microphone : A microphone, typically a Lavalier microphone, attached to a miniature FM transmitter, and that broadcasts to an FM receiver. Because the signal is transmitted, no cable is necessary between the microphone and the rest of the audio chain .inaudio recorder.

WMF Windows Media Format

wobble : To vary between recording or sampling rates. See variable-rate digital converter.

wolf note : A term used to describe the inaccuracy in pitch which can occur when an instrument such as a harpsichord, which has not been tuned to equal temperament, is played on a remote key. Also used to denote the undue stridency of a note on an instrument such as a cello, where the pitch of that note is related to the resonant frequency of the instrument.

WOM : Write-Only Memory. Memory that can be overwritten by the user, but cannot be read by the user. An example is WOM/MA (Manufacturer-Accessible) is used by some hardware manufacturers as a sort of "black box" for units returned for service as a means of recording some of the history of the device.

woofer : A loudspeaker designed to reproduce low frequencies only.

word : The smallest possible unit of digital audio; a single number (sample word) that represents the instantaneous amplitude of a sampled sound at a particular moment in time. See bit depth.

word clock : A signal internally by all digital audio devices, and externally for locking together high-end digital audio devices. Word clock is , accurate to a single sample word, usually 44.1kHz or 48kHz, i.e., the sampling rate.. Specialized hardware is required for syncing a digital audio recorderís word clock to SMPTE timecode or some other timing reference, usually through a BNC-type connector, rather than the XLR connector used by an AES/EBU null clock signal. . See self-clocking, master clock, Super Clock.

word length : See bit depth.

workprint : Copies of the original film or video used as a reference during the sound and/or picture editing process or a linear editing system. Also used during sweetening. The workprint is usually the first print made of the camera negative with all or selected takes included in their entirety, slates and all, also called dailies. (2) The edited dailies of a film in an assembly, rough cut or fine cut. Workprint is often loosely used to refer to all the edited materials, including magnetic film tracks, etc. A film copy, usually black-and-white, is sometimes referred to as a slop print, and is used to save stress of repeated rollback during the mix on the much-spliced workprint. Workprints include Acmade edge numbers and key numbers. Video copies with BITC are known as window dubs.

workstation : A : A synthesizer or sampler within which several of the tasks usually associated with electronic music production such as sequencing, effects processing, rhythm programming, and data storage on disk, and the editing of stored sequencer data can all be performed by components found within a single physical device, sometimes called a DAW by the acronym-friendly.

worktrack : The sound analog of the workprint.

worldize : To re-record a track or tracks, usually music, in the space where it would naturally occur in a film.

WORM : Write Once Read Many. Any form of memory which allows data to be stored once only, but the information can be read an unlimited number of times. Recordable CDs are an example of this, although the term generally refers to programmable ICs.

wow : A type of frequency modulation distortion which manifests itself as aof relatively slow variation in frequency of reproduced sound caused by slow speed variations in the transports of turntablesrecords, tape recorders, etc. Pitch fluctuations of 1Hz-2Hz are classed as wow, while faster variations are called flutter.

Wow and Flutter caused by any variation in the speed of the tape transport. The lower the figure the better and hence the lower the level of variation through the speakers.

WPC : Watts Per Channel. A unit intended to give an indication of the output of a power amplifier. It should be qualified by a load condition such as the impedance of a loudspeaker, e.g., 200WPC/4Ω, otherwise it is meaningless.

wrap : The parameter of tape-head alignment that determines how large an area of tape oxide is in contact with the front surface of the tape head, i.e., the surface containing the gap. Also called contact. The correct wrap is different for heads of different frontal design. The combination of wrap and tape tension determines whether the tape makes adequate contact at the gap itself.

write mode : In mixerconsole automation, the operational mode in which the system scans channel fader levels and perhaps other parameters, making continuous note of the engineer-specified initial conditions for each channel and all changes made by the engineer in real-time during a mixdown. The scanned data is continuously written to storage, either on one track of the multitrack tape itself, or onto a floppy or hard disk. If stored to disk, the multitrack tape and disk must carry identical timecodetimecodes for later reproduction of the mix by the system when operating in its read or update mode.
