The document provides definitions for various audio and sound design terms related to computer games. It includes definitions for formats such as .wav and .mp3 files, limitations including bit depth and sample rate, recording systems like MIDI and software, and concepts such as lossy compression, sampling, and sound design methodology. Each term's definition includes a short description and link to source, as well as how the term relates to the author's own production practice involving sound creation and editing software.

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.

DESCRIBE THE RELEVANCE OF THE RESEARCHED TERM TO YOUR
OWN PRODUCTION PRACTICE?
SOUND DESIGN
METHODOLOGY
Foley Artistry “Artist: a person who recreates non-computerized
sound effects for film,
television and radio”
http://www.folger.edu/documents/foleynew.pdf
Foley Artistry is relevant to my own practise from me
creating sounds form the MIDI keyboard.
Sound Libraries “a collection of sounds stored on file (for example on
CDs, DVDs, or as digital audio files)”
http://www.collinsdictionary.com/dictionar
y/english/sound-library
The sounds libraries are relevant to my own production
practise by gather all of my sound into one place for me to
use at any given time.
SOUND FILE
FORMATS
Uncompressed “restore to its uncompressed form; decompress data"
http://dictionary.reference.com/browse/uncompress
Uncompressed files were used in my work from me no
compressing them to be smaller when uploading to sound
cloud.
.wav “Waveform Audio File Format (WAVE, or more
commonly known as WAV due to its filename
extension)(rarely, Audio for Windows) is
a Microsoft and IBM audio file format standard for
storing an audio bit stream on PCs”
http://en.wikipedia.org/wiki/Wav
WAV files were used in my work with the sounds used in the
editing programme and become the final renders of my work
into .Wav files. To be heard and be used in many different
things we can do with them.
.aiff “Audio Interchange File Format." AIFF is a file
format designed to store audio data”
http://www.techterms.com/definition/aiff
.AIFF files were not used in my own production work
because mainly every file format I used in my work was Mp4
files.
.au “The Au file format is a simple audio file

format introduced by Sun Microsystems. The format
was common on NeXT systems and on early Web
pages. Originally it was headerless, being simply 8-
bit µ-law-encoded data at an 8000 Hz sample rate”
http://en.wikipedia.org/wiki/Au_file_format
.Au files were not used in my own production work because
every file format I used in my work was Mp4 files even
including the final rendered out files after editing them.
.smp “Symmetric Multiprocessing, a computer architecture
that provides fast performance by making
multiple CPUs available to complete
individual processes simultaneously
(multiprocessing)”
http://www.webopedia.com/TERM/S/SMP.html
.Smp files were not used in my own production work
because mainly every file format I used in my work was Mp4
files.
Lossy
Compression
“Lossy compression is typically associated with image
files, such as JPEGs, but can also be used for audio
files, like MP3s or AAC files”
http://www.techterms.com/definition/lossy
.mp3 “MP3, is an encoding format for digital audio which
uses a form of lossy data compression”
http://en.wikipedia.org/wiki/MP3
MP3 was used in my work when the files are rendered out
into the MP3 format just like the .WAV files.
AUDIO
LIMITATIONS
Sound
Processor Unit
(SPU)
“Integrated circuit that generates an audio signal and
sends it to a computer's speakers. The sound card can
accept an analog sound (as from a microphone or
audio tape) and convert it to digital data that can be
stored in an audio file”
http://encyclopedia2.thefreedictionary.com/Audio+pr
ocessing+unit
The SPU (Sound Processor Unit) was used in my work to hear
all of the sounds I created in my reaper projects and heard
after being rendered out.
Digital Sound
Processor (DSP)
“digital signal processing, which refers to
manipulatinganalog information, such as sound or
photographs that has been converted into
a digital form”
http://www.webopedia.com/TERM/D/DSP.html
Digital Sound Processor was used in my own production or
all of the rendered out files and all of the original unedited
files.
Random Access “RAM (pronounced ramm) is RAM was used in my work to help making the computer be

fast enough to support the reaper package files.
Mono Audio “mono sound, mono, or non-stereo sound, this early
sound system used a single channel of audio for sound
output”
http://www.webopedia.com/TERM/M/monophonic_s
ound.html
Mono Audio used in my work to be able to hear all sound
outputs coming from my work to headphones or speakers.
Stereo Audio “Stereophonic sound or, more commonly, stereo, is a
method of sound reproduction that creates an illusion
of directionality and audible perspective”
http://en.wikipedia.org/wiki/Stereophonic_sound
Stereo Audio used in my work to be able to hear all sound
outputs coming from my work to headphones or speakers.
Surround
Sound
“a system of stereophony involving three or more
speakers surrounding the listener so as to give a more
realistic effect”

outputs coming from my work to headphones or speakers.
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.

RECORDING
SYSTEMS
Analogue The analogue device reads data from a record as a
continuous signal. The opposite of analogue is digital,
these are the devices that read information in ones
and zeros.

MIDI Midi Musical Instrument Digital Interface is a technical
standard that describes a protocol, digital interface
and connectors and allows a wide variety of electronic
musical instruments, computers and other related
devices to connect and communicate with one
another.
http://en.wikipedia.org/wiki/MIDI
MIDI was used in my work when I used the MIDI keyboard
for making my own sounds from scratch and then add effects
to them to make the sounds change from when they started.
Software
Sequencers
Software sequencers usually have more features and
have the advantage of showing you a lot more
information at once because they use the computer's
screen and aren't locked into the knobs or buttons or
display of a hardware sequencer.

Software Plug-
ins
Software Plug-ins is a software component that adds a
specific feature to an existing software application.
http://en.wikipedia.org/wiki/Plug-in_(computing)
Software Plug-ins were used in my work with work when
changing my original sounds to the new sounds with the
different VST plugins to change the sounds by
Pitch,Volume,Sound and many more included in the plug-ins.

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.
http://en.wikipedia.org/wiki/MIDI_keyboard
MIDI keyboard instrument was used in my work to make
sounds in reaper using the MIDI keyboard by using it like a
normal keyboard for making sounds.
AUDIO
SAMPLING
File Size
Constraints -
Bit-depth
Bit depth is the number of bits of information in each
sample, and it directly corresponds to the resolution
of each sample.
http://en.wikipedia.org/wiki/Audio_bit_depth
Bit depth was used in my sound creations by rendering out
the final renders with 16-bit PCM as the default setting for
the bit-depth.
File Size
Constraints -
Sample Rate
Sample Rate 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.
http://en.wikipedia.org/wiki/Sampling_(signal_proces
sing)
Sample rate was used also in the rendering the files into
.WAV files at a default standard rate speed 44100 Hz.
