**Digital**All digital equipment, formats and systems represent audio in numerical code or form. Digital information is a precise way of expressing any of information that can be quantified in some way.

**Modelling**Synthesis technique whereby a sound or set of characteristics is created from a mathematical model. This can be applied to create instrument sounds as well as to simulate the response of a device such as an amplifier, effects processor or speaker to any given input.

**Amplifier**A device for increasing the power of a signal by taking power from a supply and shaping the output to match the input signal.

**Ampere**Unit of current; the amount of electricity flowing through a conductor. One Ampere is equal to the flow of 6.25x10^18 electrons through a conductor in one second.

**Modelling**Synthesis technique whereby a sound or set of characteristics is created from a mathematical model. This can be applied to create instrument sounds as well as to simulate the response of a device such as an amplifier, effects processor or speaker to any given input.

**Effects**General term applied to audio processors for dynamics, time, ambience and equalisation whether in the form of 19" rack units, guitar floor pedals, or software plug-ins.

**Ampere**Unit of current; the amount of electricity flowing through a conductor. One Ampere is equal to the flow of 6.25x10^18 electrons through a conductor in one second.

**Bass**The lowest part of the audio frequency range; in popular music, a (generally) rhythmic, low frequency melodic line emphasising the root notes of the chord progression.

**Standalone**General term denoting a software application that functions on its own, as opposed to a plug-in for use within host software such as a DAW or sequencer. Many software instruments are available in both standalone and plug-in formats.

**Stompbox**A floor-based FX unit, usually in the form of a single pedal. The effect is activated by the player's foot.
