Uncompressed video, also called Clean HDMI, is
digital video information that has not been compressed, or
was not processed with compression on it when the video
was captured directly via video capture (e.g. from a digital
camera.

.smp (Symmetric MultiProcessing) A multiprocessing architecture
in which multiple CPUs, residing in one cabinet, share the
same memory. SMP systems provide scalability. As business
increases, additional CPUs can be added to absorb the
increased transaction volume.

Lossy
Compression
Lossy file compression results in lost data and quality from
the original version. Lossy compression is typically associated
with image files, such as JPEGs, but can also be used for audio
files, like MP3s or AAC files.

.mp3 MPEG-1 or MPEG-2 Audio Layer III, more commonly referred
to as MP3, is an encoding format for digital audio which uses
a form of lossy data compression.

Digital Sound
Processor
(DSP)
A Digital Signal Processor, or DSP, is a specialized
microprocessor that has an architecture which is optimized
for the fast operational needs of digital signal processing. A
Digital Signal Processor (DSP) can process data in real time,
making it ideal for applications that can’t tolerate delays.

Random
Access
Memory
(RAM)
AM (pronounced ramm) is
an acronym for random accessmemory, a type of computer
memory that can be accessed randomly; that is, any byte of
memory can be accessed without touching the preceding
bytes. RAM is the most common type of memory found
in computers and other devices, such as printers.

Mono Audio Monaural or monophonic sound reproduction (often
shortened tomono) is single-channel. Typically there is only
one microphone, one loud speaker, or (in the case
of headphones and multiple loudspeakers) channels are fed
from a common signal path.
http://en.wikipedia.org/wiki/Monaural
Stereo Audio Stereophonic sound or, more commonly, stereo, is a method
of sound reproduction that creates an illusion of
directionality and audible perspective. This is usually
achieved by using two or more independent audio channels
through a configuration of two or more loudspeakers (or
stereo headphones)in such a way as to create the impression
of sound heard from various directions, as in natural hearing.
http://en.wikipedia.org/wiki/Stereophonic_sound
Surround
Sound
Surround sound is a technique for enriching the sound
reproduction quality of an audio source with additional audio
channels from speakers that surround the listener (surround
channels), providing sound from a 360° radius in the
horizontal plane (2D) as opposed to "screen channels"
(centre, [front] left, and [front] right) originating only from
the listener's forward arc.

Direct Audio
(Pulse Code
Modulation –
PCM)
Pulse-code modulation (PCM) is a method used to digitally
represent sampled analog signals. It is the standard form of
digital audio in computers, Compact Discs, digital telephony
and other digital audio applications. In a PCM stream, the
amplitude of the analog signal is sampled regularly at
uniform intervals, and each sample is quantized to the
nearest value within a range of digital steps.

AUDIO
RECORDING
SYSTEMS
Analogue Analog device is usually a combination of both analog
machine and analog media that can together measure,
record, or reproduce (emit[disambiguation needed])
continuous information, for example, the almost infinite
number of grades of transparency, voltage, resistance,
rotation, or pressure. In theory, the continuous information
(also analog signal) has an infinite number of possible values
with the only limitation on resolution being the accuracy of
the analog device.

Digital Mini
Disc
The MiniDisc (MD) is an obsolete magneto-optical disc-based
data storage device for 74 minutes and, later, 80 minutes, of

3. digitized audio or 1 gigabyte of Hi-MD data. The Sony brand
audio players were on the market from September 1992 until
March 2013.[1]
http://en.wikipedia.org/wiki/MiniDisc
Compact Disc
(CD)
Stands for "Compact Disc." CDs are circular discs that are 4.75
in (12 cm) in diameter. The CD standard was proposed by
Sony and Philips in 1980 and the technology was introduced
to the U.S. market in 1983. CDs can hold up to 700 MB of
data or 80 minutes of audio. The data on a CD is stored as
small notches on the disc and is read by a laser from an
optical drive. The drives translate the notches (which
represent 1's and 0's) into usable data.

Digital Audio
Tape (DAT)
Acronym for digital audio tape, a type of magnetic tape that
uses a scheme called helical scan to record data. A DAT
cartridge is slightly larger than a credit card in width and
height and contains a magnetic tape that can hold from 2 to
24 gigabytes of data. It can support data transfer rates of
about 2 MBps. Like other types of tapes, DATs are sequential-
access media.
http://www.webopedia.com/TERM/D/DAT.html
MIDI Stands for "Musical Instrument Digital Interface." It is a
connectivity standard that musicians use to hook together
musical instruments (such as keyboards and synthesizers)
and computer equipment. Using MIDI, a musician can easily
create and edit digital music tracks. The MIDI system records
the notes played, the length of the notes, the dynamics
(volume alterations), the tempo, the instrument being
played, and hundreds of other parameters, called control
changes.

Software
Sequencers
An electronic device or software program that can be
instructed to order and modify digitally stored musical
sounds for playback, as through a synthesizer.

Software
Plug-ins
In computing, a plug-in (or plugin, extension, or add-on /
addon) is a software component that adds a specific feature
to an existing software application. When an application
supports plug-ins, it enables customization. The common
examples are the plug-ins used in web browsers to add new
features such as search-engines, virus scanners, or the ability
to utilize a new file type such as a new video format. Well-
known browser plug-ins include the Adobe Flash Player, the
QuickTime Player, and the Java plug-in, which can launch a
user-activated Java applet on a web page to its execution a
local Java virtual machine.

MIDI
Keyboard
Instruments
A MIDI keyboard is typically a piano-style user interface
keyboard device used for sending MIDI signals or commands
over a USB or MIDI cable to other devices connected and
operating on the same MIDI protocol interface. This could
also be a personal computer running software such as a
digital audio workstation (DAW) that listens to and sends
MIDI information to other MIDI devices connected by cable
or running internal to the personal computer system. The
basic MIDI keyboard does not produce sound.

Bit-depth
In digital audio using pulse-code modulation (PCM), bit depth
is the number of bits of information in each sample, and it
directly corresponds to the resolution of each sample.
Examples of bit depth include Compact Disc Digital Audio,
which uses 16 bits per sample, and DVD-Audio and Blu-ray
Disc which can support up to 24 bits per sample.

Sample Rate
In signal processing, sampling is the reduction of a
continuous signal to a discrete signal. A common example is
the conversion of a sound wave (a continuous signal) to a
sequence of samples (a discrete-time signal).
