An alternative term for a transducer which converts acoustic sound waves into an electrical signal.

A collection of digital data comprising eight bits.

(Also sometimes referred to as a buss) An electrical signal path along which multiple signals may travel. A typical audio mixer contains several (mix) buses which carry the stereo mix, subgroups, the PFL signal, the aux sends, and so on. Power supplies are also fed along buses.

A term most commonly used in reference to a software fault or equipment design problem. In the context of sound recording a bug may also refer to a contact microphone.

A buffer is essentially a short term data storage facility used to accommodate variable data read or write periods, temporarily storing data in sequence until it can be processed by, or transferred to, some other part of the system. 

A device that converts breath pressure into MIDI controller data, allowing woodwind players to control synthesizers.

Beats Per Minute.

A specialised microphone where the diaphragm is placed very close to a boundary (eg. wall, floor or ceiling). In this position the direct and reflected sound adds constructively, giving a 6dB increase in sensitivity. It also avoids the comb-filtering that can occur when a conventionally placed microphone captures the direct sound along with strong first reflections from nearby boundaries. Also known as PZM or Pressure Zone Microphone.

A physical obstruction to sound waves, such as a wall, or a large solid object. When sound waves reach a boundary they create a high pressure area at the surface which is typically perceived as a build up in the level of low frequencies.

The process of mixing two or more recorded tracks together and re-recording the result onto another track.
