Wah
Wah (Wah)
A changing filter giving more and less filtering of harmonics of an
instrument's sound.
Watt
1) Unit of electrical power.
2) Unit of electrical power derived from the current (or "quantity" of
electricity) multiplied by the voltage (or "pressure" at which the current
is delivered). Stage lighting equipment is rated in Watts (or Kilowatts - 1
kW being equal to 1000W). This refers to the amount of power required to
light the lamp. A higher wattage lamp requires more power and gives a
brighter light output.
Wave
A continuous fluctuation in the amplitude of a quantity with respect to
time.
Wave flank
A term with the same meaning as Bank (a collection of sound patches in
memory).
Wave Velocity
The time it takes for one point of the waveform to travel a certain
distance.
Waveform
The shape made by the fluctuations of a quantity over time.
Waveshape
The shape made by the fluctuations of a quantity over time.
Wavelength
The length of one cycle (in feet, inches, etc.)
Wavelength
The distance measured in the direction of progression of a wave, from
any given point characterized by the same phase.
Weber
A unit that describes a number of magnetic lines of force and is used in
the measurement or statement of magnetic flux density (the strength of
magnetism).
Weighting
An equalization curve used in audio tests that compensates for the
Fletcher Munson Effect at various levels.
Wet
Having reverberation or ambience.
Whammy Bar
See Tremolo
White noise
1) A random noise used in measurements, as it has the same amount of
energy at each frequency.
2) A random energy where there is an energy distribution so that the amount
of energy is the same for each cycle, causing the noise level to increase
with frequency.
Wide Band Noise
Noise that has energy over a wide range of frequencies.
Width
Another term for Depth (the amount of change in the controlled signal by
the control signal).
Wild Sound
Sound recordings that are done completely separate from the master
recording (or picture recording) and therefore can not be synched to the
master recording.

packing onto the reel.
Window
A portion of a file shown on a screen, usually appearing as a menu on
top of the current page of data.
Windscreen
A device that reduces or eliminates wind noise from the microphone being
moved or from wind blowing into the microphone on remote location
recordings.
Wireless Microphone
A microphone with an FM radio transmitter inside of its case that
transmits a signal to an FM receiver off of the stage area.
Woodwind Controller
A device that plays like a woodwind instrument that puts out a control
voltage or MIDI command to control a sound module.
Woofer
1) A speaker that is designed to reproduce bass frequencies only.
2) A drive unit operating in the bass frequencies only. Drive units in
two-way systems are not true woofers but are more accurately described as
being mid/bass drivers.
3) Part of a speaker system designed to handle the low frequency parts of
the signal.
Word
A shortening of the term Digital Word (a number of information bits that
w communicate one value).
Workstation
A device that controls a variety of functions, designed to be operated
by one person.
Wow
A low pitch change that happens because the recorder or playback machine
fluctuating in speed slowly.
Wrap
The angle formed by the tape as it bends around the head.
Write
To record digital data onto a digital recording or into computer memory.
Write Head
The device in a digital audio tape recorder that records the bits of
digital information onto the storage medium.
Write Mode
A mode of operation of an automated console where the engineer is in
control of channel gain and the computer is storing changes in gain caused
by the engineer over time.
Write Protect
A tab on a floppy disc or a function in a unit which protects recorded
or stored data from being damaged or erased by writing over it.
