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 FILE FORMATS Uncompressed ncompressedaudio files are the most accurate digital
representation of a soundwave, but can also be the most resource-
intensive methodof recording and storingdigital audio, bothin
terms of storage and management. Their accuracymakes them
suitable for archivinganddeliveringaudioat high resolution, and
workingwith audio at a professional level, andtheyare the
'master' audio format of choice.

.wav Microsoft's native uncompressedaudioformat for Windows. While
a flexible format, capable ofstoring veryhigh qualityaudio, WAV
has a fewlimitations whichhave become apparent over its lifetime,
and extensions to the format have beendevelopedto address
them. One shortcoming identifiedinWAV is its inabilityto hold any
metadata describing its audiocontents (see BWF).
PCM bitstream audiois storedas a series of standard RIFF
(Resource Interchange File Format)chunks
File size is alsolimitedto 4Gb. This limit derives from the use of a
.wavis one of manysoundfiles, WAV has
manylimitations but WAV is Microsoft file

Lossy Compression Lossless andlossycompression are terms that describe whether or
not, in the compression of a file, alloriginal data canbe recovered
when the file is uncompressed. Withlossless compression, every
single bit of data that was originallyinthe file remains after the file
is uncompressed. All of the information is completelyrestored. This
is generallythe technique ofchoice for text or spreadsheet files,
where losingwords or financial data couldpose a problem. The
Graphics Interchange File (GIF) is an image format usedon the Web
that provides lossless compression.

Direct Audio (Pulse Code
Modulation – PCM)
Pulse-code modulation (PCM) is a methodused
to digitallyrepresent sampled analog signals. It is the standardform
of digital audio in computers,Compact Discs, digitaltelephonyand
other digital audio applications. Ina PCMstream, the amplitudeof
the analog signal is sampledregularlyat uniform intervals, andeach
sample is quantized to the nearest value within a range ofdigital
steps. http://en.wikipedia.org/wiki/Pulse-code_modulation

AUDIO RECORDING
SYSTEMS
Analogue In telecommunications, an analogue signal is one inwhich a base
carrier's alternating current frequencyis modifiedin some way,
such as byamplifying the strength ofthe signal or varyingthe
frequency, inorder to addinformation to the signal. Broadcast and
telephone transmission have conventionallyused analogue
technology.
An analogue signalcanbe representedas a series ofsine waves.
The term originatedbecause the modulationof the carrier wave is
analogous to the fluctuations ofthe humanvoice or other sound
that is being transmitted.

AUDIO SAMPLING File Size Constraints - Bit-
depth
Bit depthis the number of bits used to carrythe data ineach
sample of audio. The bit depthchosen for recording limits the
dynamic range of the recording. (Other factors inthe audiochain
mayalsolimit this, somore bits oftenwill not produce a better
recording.)http://wiki.audacityteam.org/wiki/Bit_Depth

In signal processing, samplingis the reductionof a continuous
signal to a discrete signal. A commonexample is the conversionof
a soundwave (a continuous signal)to a sequence of samples(a
discrete-time signal).
