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

SOUND FILE FORMATS Uncompressed Uncompressedformats like CD Audio, WAV, or AIFF are prettymuchperfect
representations of the audiothat was recorded.
http://www.prx.org/help/posting-audio/compressed-versus-uncompressed
.wav The Wave file format storesinformationabout the file's number of tracks
(mono or stereo), sample rate, bit depth, as well as the uncompressedraw
audiodata.

.aiff The AIFF format results inan uncompressedPCM(pulse-code modulation)

qualityof sound.

Lossy Compression Lossycompressiontechnologies attempt to eliminate redundant or
unnecessaryinformation.

.mp3 MP3 achieves its powerful compressionbystrippingout a lot of the sounds
in a songwhichour ears cannot hear, andusing complex mathematical
algorithms to reduce file sizes further. The result is that MP3 files are
around11 times smaller thanuncompressedmusic tracks.

Mono Audio Mono or monophonic describes a systemwhere all the audiosignalsare
mixed together androutedthrough a single audiochannel.

Stereo Audio True stereophonic soundsystems have two independent audiosignal
channels, andthe signals that are reproduced have a specific level and
phase relationshipto each other sothat when playedbackthrougha

Digital Mini Disc You can recordanderasefiles ona MiniDisc just as easilyas youcanon a
floppydisk. The big difference betweenthe a MiniDisc and a floppydisk is
that a MiniDisc canhold about 100 times more data (about 140 megabytes

floppy).
