The document is a glossary assignment for a games design course on sound design. It contains definitions for over 20 key terms related to sound design and production. For each term, it provides a short definition from an online source as well as any relevant details about how the term relates to the student's own production practice. The glossary covers areas such as foley artistry, sound file formats, audio limitations, recording systems, sampling, and more.

IG2 Task 1
1
Produce a glossary of terms specific to the methods and principles of sound design and production. Using a provided template, you must
research and gather definitions specific to provided glossary terms. Any definitions must be referenced with the URL link of the website you
have obtained the definition.
You must also, where possible, provide specific details of how researched definitions relate to your own production practice.

SOUND DESIGN
METHODOLOGY
Foley Artistry Foleyis the reproductionof everydaysound effects that are addedto film, video,
and other media in post-productionto enhance audioquality.

Sound Libraries a collectionof sounds storedon file (for example on CDs, DVDs, or as digital
audiofiles)

SOUND FILE FORMATS Uncompressed Uncompressedaudiofiles are the most accurate digitalrepresentationof a
soundwave, but can alsobe the most resource-intensive method ofrecording
and storing digital audio, both interms ofstorage and management. Their
accuracymakes themsuitable for archiving and deliveringaudio at high
resolution, and working withaudioat a professional level, andtheyare the
'master' audio format of choice.

.wav WAV is anaudio file format that was developedbyMicrosoft. It is sowide
spreadtodaythat it is called a standardPCaudio file format.

.aiff AIFF is short for Audio Interchange File Format, which is anaudio format initially
createdbyApple Computer for storing andtransmitting high-qualitysampled
audiodata.

.au The Au file format is a simple audio file format introducedbySun Microsystems.
The format was commononNeXT systems andonearlyWeb pages.

.smp A ".smp" file maybe one ofseveral different types of audiofile. For example, it
could be a Sample Vision audiosample file.

Lossy Compression “Lossy" compressionis the class of data encoding methods that uses inexact
approximations (or partialdata discarding) for representing the content that has
been encoded. Such compressiontechniques are used to reduce the amount of
data that would otherwise be needed to store, handle, and/or transmit the
representedcontent.

.mp3 MP3 is anaudio coding format for digital audiowhich uses a form of lossy data
compression. It is a common audio format for consumer audiostreaming or
storage, as well as a de facto standard ofdigital audiocompressionfor the
transfer andplaybackof music on most digital audioplayers.

AUDIO LIMITATIONS Sound Processor Unit (SPU) A sound card (also knownas anaudiocard) is aninternal computer expansion
card that facilitates economical input andoutput of audiosignalsto and from a
computer under control of computer programs. The termsoundcardis also
appliedto external audiointerfacesthat use software to generate sound, as
opposedto using hardware inside the PC.

Digital Sound Processor
(DSP)
Digital signal processing(DSP) is the mathematical manipulationof an
informationsignal to modifyor improve it insome way. It is characterizedbythe
representation of discrete time, discrete frequency, or other discrete domain
signals bya sequence of numbers or symbolsandthe processingof these signals.

Random Access Memory
(RAM)
Random-access memory(RAM/ræm/) is a formof computer data storage. A
random-accessmemorydevice allows data items to be readandwrittenin
roughlythe same amount oftime regardlessof the order in whichdata items are
accessed.

Mono Audio Mono audiois one of the "Accessibility" featuresthat you canenable through
the systemsettings. It allows youto listen through onlyone earphone. Thus the
term "stereophonic" applies to so-called "quadraphonic" and"surround-sound"
systems as well as the more commontwo-channel, two-speaker systems. It is
often contrasted withmonophonic, or "mono" sound, where audiois inthe form
of one channel, often centredinthe sound field (analogous to a visual field).
Stereo sound is now common inentertainment systems suchas broadcast radio
and TV, recorded music andthe cinema.

Stereo Audio Stereo, is a methodof soundreproductionthat createsanillusionof
directionalityand audible perspective. This is usuallyachievedbyusingtwo or
more independent audio channelsthrougha configurationof twoor more
loudspeakers (or stereo headphones) insucha wayas to create the impression
of sound heard fromvarious directions, as in naturalhearing.
http://en.wikipedia.org/wiki/Stereophonic_sound
Surround Sound Surroundsoundis a technique for enrichingthe soundreproductionqualityof an
audiosource withadditional audiochannels from speakers that surroundthe
listener (surround channels), providing sound from a 360° radius inthe
horizontalplane (2D) as opposedto "screen channels"(centre, [front] left, and
[front] right) originatingonlyfrom the listener's forward arc.

Direct Audio (Pulse Code
Modulation – PCM)
PCM stands for Pulse Code Modulation. PCMtechnologyis a means bywhich
standardaudiosignals (whichare representedbywaveforms)are convertedto
digital audiosignals(which are representedby1's and 0's - muchlike computer
data)withlittle, or no, compression.
