- 1. Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games 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. Name: Callum Deighton RESEARCHED DEFINITION (provide short internet researched definition and URL link) DESCRIBE THE RELEVANCE OF THE RESEARCHED TERM TO YOUR OWN PRODUCTION PRACTICE? SOUND DESIGN METHODOLOGY Foley Artistry A technical process by which sounds are created or altered for use in a film, video, or other electronically produced work. http://www.thefreedictionary.com/foley In my work i have altered some sounds i recorded around the college to make a sound that you would find that was relatable to the subject of work. Sound Libraries a collection of sounds stored on file (for example on CDs, DVDs, or as digital audio files) http://www.collinsdictionary.com/dictiona ry/english/sound-library When we were using the sound programs there was a sound library available for us to use. SOUND FILE FORMATS Uncompressed Uncompressing (or decompressing) is the act of expanding a compression file back into its original form. http://whatis.techtarget.com/definition/un compressing-or-decompressing

AIFF is an audio format originally developed by Apple Computer for storing high-quality sampled audio data. http://pc.net/glossary/definition/aiff .au A digital audio file format from Sun that is used on the Internet and can be played by a Java program. http://www.yourdictionary.com/au-file .smp A multiprocessing architecture in which multiple CPUs, residing in one cabinet, share the same memory. http://encyclopedia2.thefreedictionary.co m/SMP Lossy Compression A compression technique that does not decompress data back to 100% of the original. http://www.pcmag.com/encyclopedia/t erm/46335/lossy-compression
- 3. Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 3 .mp3 a computer file format for the compression and storage of digital audio data. http://www.merriam- webster.com/dictionary/mp3 when we finished making our sounds they would be exported into mp3 file formats for us to listen to and upload. AUDIO LIMITATIONS Sound Processor Unit (SPU) Digital Sound Processor (DSP) A digital sound processor is a tool that incorporates computer technology to change the technical aspects of analog sound. http://www.ehow.com/facts_5879513_d efine-digital-sound- processor.html#ixzz2zTVn5xep Random Access Memory (RAM) Random access memory (RAM) is the best known form of computer memory. http://computer.howstuffworks.com/ram. htm RAM would be used when we would save the sounds to the computer in order to upload them. Mono Audio Mono or monophonic describes a system where all the audio signals are mixed together and routed through a single audio channel. http://www.mcsquared.com/mono- stereo.htm We had the option of using mono sound headphones when we were making the sounds. Stereo Audio Sound that is directed through two or more speakers so that it seems to surround the listener and to come from more than one source http://www.oxforddictionaries.com/definit ion/english/stereo We had the option of using stereo sound headphones when we were making the sounds.

Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 4 Surround Sound a system for playing sounds, especially in cinemas, that uses three or more loudspeakers so that the person listening seems to be surrounded by the sound. http://dictionary.cambridge.org/dictionary/british /surround-sound We had the option of using surround sound headphones when we were making the sounds. Direct Audio (Pulse Code Modulation – PCM) Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. http://en.wikipedia.org/wiki/Pulse- code_modulation When we would upload the sounds to the program it would be played as direct audio. Analogue analogue technology uses changing physical quantities such as voltage to store data. http://www.ldoceonline.com/dictionary/a nalogue When we would export the sound it would change the file to a sound file and not a program file. Digital Mini Disc a digital disc medium for storing music or data where a small disc is housed in a cartridge and is either recordable or playback. http://dictionary.reference.com/browse/ minidisc We have not used a Digital Mini Disc so far in our work.

Software Plug-ins They are called that because these are little computer applications that run inside a "host" application, i.e., a sequencer, typically. These plugin devices are very important, as they have led the software revolution towards our virtual studios which is changing all recording studios, both home and pro. Today there are few hardware devices left that cannot be emulated by plugins and software. As you see from this page, software based synthesizers, effects processors, samplers and multi- track recorders can all work together on one single computer. http://tweakheadz.com/software-plugins/ Software plugins were also available for use on the program, they would be very useful as they are very in depth with the available changes such as changing the pitch, tempo, depth and echo among many other options.

The MIDI portion indicates that the instrument has a communication protocol built in that allows it to communicate with a computer or other MIDI-equipped instrument. http://www.wisegeek.com/what-is-a- midi-keyboard.htm On the program there was a variety of keyboard based instruments for us to use which would be very crucial in making some of the sounds. AUDIO SAMPLING File Size Constraints - Bit-depth In digital audio, bit depth describes the number of bits of information recorded for each sample. http://en.wikiaudio.org/Bit_depth It was possible to view the bit depth of each sound i made. File Size Constraints - Sample Rate Sampling is the process of measuring an audio signal at specific points in time. http://stereos.about.com/od/glossaryofte rmss/g/sampling.htm
