Synthesizer
An electronic musical instrument designed to create a wide range of sounds, both imitative and abstract.

(System Exclusive) A part of the MIDI standard that allows manufacturers to define their own specific message formats, commonly used to dump and load a specific product’s patch data.
A system designed to enable voice communication between rooms.
The part of a tape machine that transfers magnetic energy to the tape during recording, or reads it during playback.
The rate of the 'beat' of a piece of music measured in beats per minute.
– A steady, fixed level tone recorded onto a multitrack recording, or passed over a signal connection to test the signal path and act as a reference when matching levels.
Total Harmonic Distortion. A measure of the linearity of a device. The THD+N measurement includes the noise contribution as well and is an indication of the quality of an audio product.
A MIDI connector which passes on the signal received at the MIDI in socket.
The tonal 'colour' of a sound.
Referring to the tones that can be created by a synthesizer (see multi-timbral and bi-timbral)
Shorthand for 'Toshiba Link', an optical audio connection. See S/PDIF.
The term dates back to multitrack tape where the tracks are physical stripes of recorded material, located side by side along the length of the tape.
The process of recording individual tracks to a multichannel recorder. Tracking is also often discussed in the context of MIDI guitar synthesizers or controllers where the MIDI output attempts to track the pitch of the guitar strings.
An electrical device in which two or more separate and electrically isolated coils of wire are wound around a common ferromagnetic core. Alternating Current passing through one coil creates a varying magnetic field which induces a corresponding current in the other coil(s). In audio applications transformers are often used to convey a signal without a direct electrical connection, thus providing 'galvanic isolation' between the source and destination. Winding a transformer with different numbers of turns for each coil allows the output voltage to be increased or decreased in direct proportion – a feature widely employed in mains power-supply transformers to reduce the mains voltage to something more appropriate for the circuitry, for example, or in microphone preamp step-up transformers.
A symmetrical triangular shaped wave containing odd harmonics only, but with a lower harmonic content than the square wave.
TRS refers to the 3-terminal 'Tip, Ring and Sleeve' format of various types of jack plug, typically used either for stereo unbalanced connections (such as on headphones) or mono balanced connections (such as for line-level signals). A 2-terminal alternative is also available, referred to as the TS (Tip, Sleeve) version, used for mono unbalanced signals. The term is applicable to A-type, mini-jack, B-type, and Bantam connectors.
– A form of digital audio meter which is capable of determining the absolute amplitude value of a digital signal by using oversampling to fully reconstruct the waveform.
A metal bar within a guitar neck which is tensioned so as to counteract the tendency for the neck to bend under the tension of the strings.

The colloquial term to describe a loudspeaker drive unit optimised for the reproduction of high frequencies. (See Woofer).
