An electronic device that boosts extremely weak signal voltages, such as those from microphones or mag heads, to a level that is usable by power amplifiers.

Recording and/or mixing sound on location during the film or video shoot. Typically this has been recorded to an analog Nagra reel-to-reel machine, though DAT recorders and other digital formats are now making significant inroads.

A reference to the standard width magnetic audio tape which is used to record film production sound.

The process of mixing all edited music, effects and dialog tracks of a film or video production to mono, stereo, multichannel or whatever audio format is desired for the final print master.

In audio systems, noise is the electrical interference or other unwanted sound introduced into the system (i.e. hiss, hum, rumble, crosstalk, etc).

A phenomenon whereby one or more sound ‘trick’ the ear into not hearing other, weaker, sound that are also present.

This is a shifting of output voltage relative to input by an amount which is disproportional to frequency. This will not detectable until it an amplifier.

The displacement of a waveform in time. Some electrical components introduce phase shift into a signal. When various frequencies are displaced differently, distortion occurs. Electrical cancellation may occur when two equal signals are out of phase. However, this may also be used are a encoding method where the shift is removed on playback (similar to…

A method of remotely powering the preamplifier or impedance converter which is buitlt into many microphones by sending a voltage along the audio cable.
