A format used for transmitting synchronisation instructions between electronic devices within the MIDI protocol.

– A specialist form of coincident microphone array which, when decoded to left-right stereo, creates an equivalent XY configuration. In the MS array one microphone is pointed directly forward (Mid) while the second is arranged at 90 degrees to point sideways (Side). The Mid microphone can employ any desired polar pattern, the choice strongly influencing the decoded stereo acceptance angle. The Side microphone must have a figure-eight response and be aligned such that the lobe with the same polarity as the Mid microphone faces towards the left of the sound stage. Adjusting the relative sensitivity of the Mid and Side microphones affects the decoded stereo acceptance angle and the polar patterns of the equivalent XY microphones.

A dynamic microphone where the diaphragm supports a coil of wire which moves within a magnetic field. When sound causes the diaphragm to vibrate a small electrical current is generated within the coil. The same technology is used in reverse for a moving coil loudspeaker, in which a powerful current is passed through the coil, causing the diaphragm (cone) to move in response.

The main circuit board within a computer into which all the other components plug or connect.

A synthesizer that can play only one note at a time (see also Polysynth and Paraphonic)

One note at a time.

A single channel of audio.

A line-level audio signal control device used to select and condition input signals for auditioning on one or more sets of monitor loudspeakers. Some monitor controllers also incorporate facilities for studio talkback and artist cue mixes.

A device used to convert an electrical audio signal into an acoustic sound wave. An accurate loudspeaker intended for critical sound auditioning purposes. Also used to refer to a computer display screen (VDU), or the act of auditioning a mix or a specific audio signal.
