The frequency at which the crossover stops sending the signal to one speaker and starts sending it to another.
The unwanted leakage of an audio signal between two audio channels—for example, overlapping signals between channels on a mixing console, or overlapping audio between two tracks of audiotape.
In general terms, a cue is the starting point for a piece of music or section of music. Depending on the context, the word “cue” may describe: 1) The point at which a musician or vocalist is supposed to start playing or singing; 2) The audio fed to the musicians through headphones so they can determine when to start playing/singing; 3) A specific location point on the music timeline within a DAW or on the tape; or 4) To set the tape or disc to a certain starting point in the song (“cueing” the tape). A cue can even refer to an entire section of music being used for video production. (Confusing, huh?)
The frequency in a filter beyond which other frequencies are attenuated.
The rate of reduction of the frequencies beyond the passband of a filter. The slope is described as the number of dB the filter reduces the signal for each octave past the cutoff frequency.
One complete expression of a waveform beginning at a certain point, progressing through the zero line to the wave’s highest and lowest points, and returning to the same value as the starting point. One complete vibration or sound wave.
Abbreviation for “D-subminiature connector,” a D-sub is a multipin connector that is most often used to connect a computer to a VGA monitor, but also used occasionally in digital audio applications in the recording studio.
Abbreviation for Digital to Analog conversion, which changes digital data numbers (digital audio signal) into discrete voltage level. The reverse process of A/D.
The connection of three or more devices in a series, where the audio signal passes through one device to reach a second, and through the second to reach the third, etc.
The reduction of energy in a vibrating system, through friction. Can refer to the reduced amplitude in an electrical signal, or the stifled vibrations of a musical instrument (for example, the damper pedal on an acoustic piano).
Describes an amplifier’s ability to restrain the pushback motion (back-EMF) of the loudspeaker cone when the audio signal stops.
An abbreviation for Digital Audio Workstation, a device or software program designed for recording and mixing audio digitally.
An abbreviation for decibel, a measurement ratio that compares signal strengths (usually audio levels).
A series of noise reduction systems, named for the company that developed them. DBX noise reduction has been less commercially successful than the more widely known Dolby systems, but is still found on occasion in recording studios.
