AA//DD - short for Analog to Digital Conversion. The conversion of
analog data or information into digital or binary form (See
binary).
AASSIIO
O – Audio Stream Input Output. ASIO, developed by
Steinberg, is a cross-platform, multi-channel audio transfer
protocol. It allows software to have access to the multi-channel
capabilities of a wide range of powerful sound cards.
BBiinnaarryy - A digital numbering system based on two where data
is expressed as combinations of "0"s and "1"s). Bit - A single
unit of digital information expressed as a "0" or "1.”
CCoorree AAuuddiioo - This is an ultra-low latency, high quality
MAC-compatible audio driver that is built directly in to the OS
X operating system.
DDeecciibbeell ((DDBB)) - A unit of measurement for expressing sound
pressure level (SPL), signal level and variation or differences in
signal level.
DDiiggiittaall TToo AAnnaalloogg CCoonnvveerrtteerr - A circuit used to change binary
data that make up the digital audio signal into discrete voltage
levels that approximate the original analog audio waveform.
Abbreviated as D/A converter.
DDSSPP - An abbreviation for Digital Signal Processing (Any signal
processing done after an analog audio signal has been
converted into digital audio.
DDyynnaam
miicc PPrroocceessssiinngg ((DDyynnaam
miicc SSiiggnnaall PPrroocceessssiinngg)) - An signal
processing system which automatically changes the gain to
maintain a preset level ratio or relationship between the loudest
and quietest passages of music.
DDyynnaam
miicc RRaannggee - The level difference, expressed in dB, between
the loudest level and quietest level of a recording or live audio
source.
FFiilltteerr - A circuit that removes or acts on certain frequency signals
above or below a predetermined point called a cut-off
frequency.
FFrreeqquueennccyy - The rate or speed at which an audio source
generates complete cycles in one second. The number of cycles
that occur in one second is call hertz (Hz).
FFrreeqquueennccyy RRaannggee - The range of frequencies over which an
electronic device delivers its best performance or over which a
sound source will produce substantial energy.
FFrreeqquueennccyy RReessppoonnssee - A plot or graph of frequencies that an
audio device, such as a mic, amplifier or speaker, can accurately
reproduce within stated parameters or conditions.
HHaarrm
moonniiccss - A tone along with whole-number multiples of the
fundamental tone that distinguish the pitch of a particular
instrument or sound.
HHaarrm
moonniicc DDiissttoorrttiioonn - The occurrence of harmonics in the output
signal of a playback device or amplifier which were not present
in the original input signal.
HHeerrttzz ((HHzz..)) - A unit of frequency measurement used to express
the number of complete cycles occurring in a one-second
interval. Abbreviated as Hz.
II//O
O - Short for "Input/Output." A port or in-line control for
channeling the flow of signal data to and from a device.
kkHHzz - The Abbreviation for kilohertz (1,000 Hz).
LLEEDD - See light emitting diode.
