Bandpass Filter
A type of filter used to eliminate high- and low-range frequencies around a specific frequency, resulting in more distinctive sound

The available "opening" through which information can pass. In audio, the bandwidth of a device is the portion of the frequency spectrum that it can handle without significant degradation. In digital communications, the bandwidth is the amount of data that can be transmitted in a given period of time.

(1) A set of patches
(2) Any related set of items, e.g., a filter bank (a set of filters that work together to process a single signal).

batch process
A technique that permits more than one file or operation to be performed with a single command.

baud rate
Informally, the number of bits of computer information transmitted per second. MIDI transmissions have a baud rate of 31,250 (31.25 kilobaud), while modems typically have a much lower rate of 2,400, 9,600, or 14,400 baud.

Named for Alexander Graham Bell, who did the original scientific investigations; Also see decibel.

To change pitch in a continuous sliding manner, usually using a pitch-bend wheel or lever. See pitch-bend.

Short for "Basic Input Output System" - the computer mainboard's "cerebral cortex"; it resides in a memory component on the board. The BIOS is started first when a computer is booted; it executes basic chores for the operating system such as managing the expansion cards plugged into the slots.

The smallest possible unit of digital information, numerically either a 1 or a 0. Digital audio is encoded in words that are usually eight, 12, or 16 bits long (the bit resolution). Each added bit represents a theoretical improvement of about 6dB in the signal-to-noise ratio.

The number of bits per given time interval, used as a measure of information flow. Digital audio bitrate is often given in units of kbps (kilo bits per second).

Often used to describe the resolution or quality of each sample in a digital audio stream. It is the number of bits (0's and 1's) used to describe the amplitude or volume of an audio signal at a specific point in time. The higher the number, the more precisely the original or intended audio signal can be (re)produced. See Digital Audio Basics for a more detailed explination.

General term for amplifying or increasing the level of signals.

Short for "Beats Per Minute" - increments of musical tempo.

brick-wall filter
A lowpass filter at the input of an analog-to-digital converter, used to prevent frequencies above the Nyquist limit from being encoded by the converter. See Nyquist frequency, aliasing.

A temporary storage of space used as a reserve to insure a smooth flow of data. buffer: An area of memory, used for recording or editing data before it is stored in a more permanent form.

bulk dump
> data dump.

In computer jargon, this general term refers to data, address and control circuits., The term describes the circuits via which the CPU communicates with peripheral devices and expansion cards (see PCI, ISA).

Bus width
Refers to the maximum number of bits that can be transported via the bus simultaneously, i.e. the de facto number of parallel circuits.

Busmaster cards
Internal computer expansion cards that access the system memory to execute data transport without requiring CPU performance and thus free performance power for other tasks.

A group of eight binary digits (bits) processed as a unit by a computer and used especially to represent an alpha-numeric character; also see word.
