Abbreviation for Beat Per Minute, a standard way to define tempo, often used in electronic music and sequencing software.

A type of small "twist and lock" RF connector often used with coaxial cables and antennas in wireless systems. Also used in audio and video to carry clock signals. A BNC male connector has a pin that connects to the primary conducting wire and then is locked in place with an outer ring that turns into a locked position.

Also referred to as amps, amperage is a measure of electrical current. An ampere is the unit of measure for the rate of electron or current flow past a certain point and in a given amount of time, through an electrical conductor.

The ability of a radio receiver to reject interference from an undesired signal on another nearby channel frequency. In wireless applications, unless the frequency separation between the desired signal and the adjacent signal is specified, the term is generally not of any practical significance.

An electronic device that consists of a Radio Frequency (RF) signal splitter, preceded by an RF amplifier that compensates for the RF loss of the splitter. Used to allow one antenna to feed several receivers.

The time it takes from when a disc access command is issued until the read/write head reaches the data sector requested. Access time is important in data intensive situations like hard disk recording, multimedia playback, and digital video applications. Lower access times are better.

Audio Interchange File Format (AIFF) is a file format for storing digital audio data. It supports a variety of bit resolutions, sample rates and channels of audio. The format has been embraced by the Apple platforms, but is also widely used in professional programs that process digital audio data.

Automatic Gain Control (AGC) is a circuit that automatically adjusts the level of incoming audio so as to optimize the record level of the receiving device. Mostly employed in low cost audio and video recorders to avoid the complication of manual adjustment.

Digidesign Audio Engine is the underlying code that allows Digidesign software communicate with computer platforms and operating systems. DAE is required for third party software to access Digidesign hardware. Prior to HD systems, DAE was an actual separate application. For HD systems, DAE is now integrated into the Pro Tools application.

Also sometimes referred to as dBv, it is dB referenced to voltage. 0dB equals 0.775 volts.
