Phaser Guide, Meaning , Facts, Information and Description
A phaser is an electronic audio signal processor used to distort a sound signal by mixing a dry, or unprocessed, signal with copy of itself that has been filtered through an all-pass phase shift network. As the filtered sound signal is mixed with the dry signal, the effect is that of a comb filter, notching out and reinforcing frequencies at fixed intervalss up the frequency spectrum. When the all-pass filtered signal alone is heard at the output, the effect is commonly referred to as vibrato.In motion picture or television production, the effect created by a phaser is often used to imply that the sound is synthetically generated (e.g. a computer or robot voice). The technique works because the frequency filtering produces sound we associate with mechanical sources, which only generate specific frequencies, rather than natural sources, which produce a range of frequencies.
Phaser is a trade name for some makes of laser printer.
Phasers are a weapon in the fictional series Star Trek. Phaser is an acronym for "PHASed Energy Rectification."
