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: 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 Foley is the reproduction of everyday sound effects that are added to film, video, and other media in post- production to enhance audio quality. These reproduced sounds can be anything from the swishing of clothing and footsteps to squeaky doors and breaking glass. http://en.wikipedia.org/wiki/Foley_(filmmaking) I have several foley artistry sounds. We have manually recorded our sounds then enhanced/ or heavily edited them using the Reaper software. Sound Libraries A sample library is a collection of digital sound recordings, known as samples, for use by composers, arrangers, performers, and producers of music. The sound files are loaded into a sampler - either hardware or computer-based - which is then used to create music. http://en.wikipedia.org/wiki/Sample_library We are currently working on a project involving our sample libraries of our produced sounds. They’re 6 samples for each category ranging from sci-fi to action sequences produced with our audio editing software. SOUND FILE FORMATS Uncompressed There is one major uncompressed audio format, PCM, which is usually stored in a .wav file on Windows or in a .aiff file on Mac OS. The AIFF format is based on the Interchange File Format (IFF). The WAV format is based on the Resource Interchange File Format (RIFF), which is similar to IFF. WAV and AIFF are flexible file formats designed to store more or less any combination of sampling rates or bitrates. This makes them suitable file formats for storing and archiving an original recording. http://en.wikipedia.org/wiki/Audio_file_format When we save and or complete our work, the file always becomes a compressed piece of work in order to save storage space. And also to make the file run faster.
Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 2 .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 bitstream on PCs. It is an application of the Resource Interchange File Format (RIFF) bitstream format method for storing data in "chunks", and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. http://en.wikipedia.org/wiki/WAV The wav file is well used in my work. The wav file is the final exported and rendered file that I use once created my jingles and other sound work that I have produced during lesson. Also Many of my manually recorded audio files that I went out to record were WAV files to begin with. .aiff Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintoshcomputer systems. http://en.wikipedia.org/wiki/Audio_Interchange_File_Format We currently have not used this in our course work. .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 We currently have not used this in our course work. .smp Music file used by SmartMusic, a music practice application for band, orchestra, and voice; saves an accompaniment that can be used for practicing solos and other musical parts; includes the sheet music information and can be used for assessment; replaced by the .SMPX in Finale 2014. http://www.fileinfo.com/extension/smp We currently have not used this in our course work.
Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 3 Lossy Compression In information technology, "lossy" compression is the class of data encoding methods that uses inexact approximations (or partial data discarding) for representing the content that has been encoded. Such compression techniques are used to reduce the amount of data that would otherwise be needed to store, handle, and/or transmit the represented content http://en.wikipedia.org/wiki/Lossy_compression We currently have not used this in our course work. .mp3 MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an encoding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. http://en.wikipedia.org/wiki/MP3 Also Mp3 is well used when exporting rendered and completed sound work that I have created. It is also a very common type of sound file, which many sound engines/software use because of its popularity with sound etc. 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, or accept digitized audio signals (as from an audio file) and convert them to analog signals that can be played on the computer's speakers. On a personal computer, the sound card is usually a separate circuit board that is plugged into the motherboard. http://encyclopedia2.thefreedictionary.com/Audio+processing+unit The sound processing units themselves are integrated in today’s pc’s laptops etc that we use to create our audio work on. Digital Sound Processor (DSP) The goal of DSP is usually to measure, filter and/or compress continuous real-world analog signals. The first step is usually to convert the signal from an analog to a digital form, by sampling and then digitizing it using an analog-to-digital converter (ADC), which turns the analog signal into a stream of numbers. However, often, the required output signal is another analog output signal, which requires a digital-to-analog converter (DAC). Even if this process is more complex than analog processing and We currently have not used this in our course work.
Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 4 has a discrete value range, the application of computational power to digital signal processing allows for many advantages over analog processing in many applications, such as error detection and correction in transmission as well as data compression. http://en.wikipedia.org/wiki/Digital_signal_processing Random Access Memory (RAM) Random-access memory (RAM) is a form of computer data storage. A random-access memory device allows data items to be read and written in roughly the same amount of time regardless of the order in which data items are accessed.In contrast, with other direct-access data storage media such as hard disks, CD-RWs, DVD- RWs and the older drum memory, the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement delays. http://en.wikipedia.org/wiki/Random-access_memory Ram is a valuable piece of hardware needed for editing software’s. Either its 3d modelling or even audio editing. A good amount of RAM is needed to keep enough space for the editing software to keep working correctly. Mono Audio Monaural or monophonic sound reproduction (often shortened to mono) is single-channel. Typically there is only one microphone, one loudspeaker, or (in the case of headphones and multiple loudspeakers) channels are fed from a common signa lpath. In the case of multiple microphones the paths are mixed into a single signal path at some stage. http://en.wikipedia.org/wiki/Monaural We currently have not used this in our course work. Stereo Audio Stereophonic sound or, more commonly, stereo, is a method of sound reproduction that creates an illusion of directionality and audible perspective. This is usually achieved by using two or more independent audio channels through a configuration of two or more loudspeakers (or stereo headphones)in such a way as to create the impression of sound heard from various directions, as in natural hearing http://en.wikipedia.org/wiki/Stereophonic_sound Most of our work is used by default with stereo audio enabled.
Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 5 Surround Sound Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (centre, [front] left, and [front] right) originating only from the listener's forward arc. http://en.wikipedia.org/wiki/Surround_sound We have tested surround sound type techniques, using ‘’Pan’’ which is used to transfer the sound from ear to the other. This can be very useful to create immersion, and make the sound itself very surround sound style. Direct Audio (Pulse Code Modulation – PCM) Although abbreviation PCM stands for Pulse Code Modulation, we understand it as general digital audio processing with volume samples generated in continuous time periods. The analog signal is recorded via analog to digital converters (ADC). The digital value (de-facto a volume at a specific time) obtained from ADC can be further processed. The following picture shows a perfect sinus waveform: http://www.alsa-project.org/alsa-doc/alsa- lib/pcm.html We currently have not used this in our course work. AUDIO RECORDING SYSTEMS Analogue Analog recording methods store signals as a continual wave in or on the media. The wave might be stored as a physical texture on a phonograph record, or a fluctuation in the field strength of a magnetic recording. This is different from digital recording of which among many possibilities include digital audio and digital video, which digital signals are represented as data or discrete numbers. http://en.wikipedia.org/wiki/Analog_recording We currently have not used this in our course work. Digital Mini Disc The MiniDisc (MD) is an obsolete magneto-optical disc- We currently have not used this in our
Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 6 based data storage device for 74 minutes and, later, 80 minutes, of digitized audio or 1 gigabyte of Hi-MD data. The Sony brand audio players were on the market from September 1992 until March 2013. http://en.wikipedia.org/wiki/MiniDisc course work. Compact Disc (CD) Known by its abbreviation, CD, a compact disc is a polycarbonate with one or more metal layers capable of storing digital information. The most prevalent types of compact discs are those used by the music industry to store digital recordings and CD-ROMs used to store computer data. http://www.webopedia.com/TERM/C/compact_disc.html We currently have not used this in our course work. Digital Audio Tape (DAT) Digital Audio Tape (DAT or R-DAT) is a signal recording and playback medium developed by Sony and introduced in 1987.[1] In appearance it is similar to a Compact Cassette, using 4 mm magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm × 54 mm × 10.5 mm. As the name suggests, the recording is digital rather than analog http://en.wikipedia.org/wiki/Digital_Audio_Tape We currently have not used this in our course work. MIDI Pronounced middy, an acronym for musical instrument digital interface, a standard adopted by the electronic music industry for controlling devices, such as synthesizers and sound cards that emit music. http://www.webopedia.com/TERM/M/MIDI.html MIDI is the keyboard that we use to ‘’paint’’ or jingle/s together. Used for making certain tunes within our project using different instruments. Software Sequencers A music sequencer (or simply sequencer) is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically MIDI or CV/Gate, and possibly audio and automation data for DAWs and plug- ins. http://en.wikipedia.org/wiki/Music_sequencer The software we currently use for our audio production work, called ‘’Reaper’’ already implements sequences to aid us for a much easier work flow.
Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 7 Software Plug-ins In computing, a plug-in (or plugin, extension, or add- on / addon) is a software component that adds a specific feature to an existing software application. When an application supports plug-ins, it enables customization. The common examples are the plug-ins used in web browsers to add new features such as search-engines, virus scanners, or the ability to utilize a new file type such as a new video format. Well-known browser plug-ins include the Adobe Flash Player. http://en.wikipedia.org/wiki/Plug-in_(computing) With the software we currently use ‘reaper’ it already comes with several VST’S and VSTI’S that help us to manipulate raw sounds etc. MIDI Keyboard Instruments A Musical Instrument Digital Interface (MIDI) keyboard is a musical instrument like a piano keyboard. 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 The MIDI instruments are used to create my jingles and other sound production that through the REAPER software. It produces a range of different sounds with all sorts of instruments. AUDIO SAMPLING File Size Constraints - Bit-depth Bit depth is the number of bits used to carry the data in each sample of audio. The bit depth chosen for recording limits the dynamic range of the recording. (Other factors in the audio chain may also limit this, so more bits often will not produce a better recording. http://wiki.audacityteam.org/wiki/Bit_Depth Bits are usually selected to 16 when im rendering my final completed sound or sounds. The software itself currently handles bit depth for us. File Size Constraints - Sample Rate In signal processing, sampling 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 (a discrete-time signal).A sample refers to a value or set of values at a point in time and/or space. Whenever we start some sort of audio projects, we have to keep in mind he amount of storage we have. And how much he file size is on its own.
