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 . 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, such a. Used . s 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
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 . 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 by s. Used . pacing the mics out, but this will not fully correct the problem and can lead to muddy sound from delay artifacts.
Hertz - A unit of measure for frequency generally applied to waveforms, one Hertz is equal to one cycle in one second. It is abbreviated Hz so that 100 Hz would be 100 cycles per second. However, the unit m. Used . ay be applied to periodic events other than waveforms like the second hand on a clock, which would cycle at 1 Hz, or a human heart that may beat at 1.2 Hz. Named after the German physicist H. Used . einrich Rudolf Hertz, the name was established in 1930, but did not replace the term cycles per second until the 1970s.
