Amplitude - Amplitude is a nonnegative scalar measure of a wave's magnitude of oscillation, that is, magnitude of the maximum disturbance in the medium during one wave cycle.

Sometimes this distance . Used Audio. is called the "peak amplitude", distinguishing it from another concept of amplitude, used especially in electrical engineering: the root mean square (RMS) amplitude, defined as the squar. Used Audio. e root of the temporal mean of the square of the vertical distance of this graph from the horizontal axis. The use of peak amplitude is unambiguous for symmetric, periodic waves, like a sine wave, a square wave, or...

AB - A stereo recording technique. Two microphones of the same make and model are located next to one another in , and point in the same direction. The left mic is panned hard left on the mixer. The right. Used Audio. mic is panned hard right.

This technique has flaws, such as audio reflections from each mic which can cause comb filtering (narrow coverage). This can be somewhat corrected. Used Audio. by spacing the mics out, but this will not fully correct the problem and can lead to muddy sound from delay artifacts.

Enhancers - Enhancers are outboard audio effects used to improve the clarity of the sound.. Used Audio. . Used Audio. ...

Ampere - The ampere (symbol: A) is the SI base unit of electrical current equal to one coulomb per second. It is named after André-Marie Ampère, one of the main discoverers of electromagnetism.

Th. Used Audio. e ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, w. Used Audio. ould produce between these conductors a force equal to 2×10–7 newton per metre of length....

Alternating Current - An alternating current (AC) is an electrical current where the magnitude and direction of the current varies cyclically, as opposed to direct current, where the direction of the current stays constan. Used Audio. t. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy. However in certain applications different waveforms are used, s. Used Audio. uch as triangular or square waves.

Used generically, AC refers to the form in which electricity is delivered to businesses and residences. However, audio and radio signals carried on electrical wire ar
