refers to a sound quality that results from not having
more than the natural amount of treble. The opposite of

Watt
- A unit of energy or heat, one horsepower is 745.7
watts. Amplifiers deliver watts only when they must
drive speakers as it is only when driving speakers are
they confronted with a workload measurable in watts.
This is the reason that watts vary in reverse
proportion to variation of resistance of the speakers.
Less resistant speakers (rated at fewer ohms) require
more watts to drive.
·
Watts
Per Channel -
The Federal Trade Commission in North America has
determined that amplifiers sold will have a power rating
in watts per channel through an 8ohm load.
·
White
Noise
- Noise that has equal
energy at each frequency. White noise has much more
treble energy than pink noise.
·
Widescreen -
Video displayed in any format wider than the
conventional TVs 4:3 standard. Usually this means 16:9,

Media Audio -

Woofer
- Any speaker system's driver that is designed to handle
the low end of the audio spectrum, or a speaker driver
designed to reproduce low frequencies. Usually in full
size speaker systems one or multiple woofers can
reproduce sounds just short of the subwoofers
capabilities.

Wow-and-Flutter
- A measurement of speed instability in analog equipment
usually applied to cassette transports and turntables.
Wow is slow-speed variations, and flutter is fast-speed
variations. Lower percentages are better. |
