Transcript

  • 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: Lewis Brady RESEARCHED DEFINITION (provide short internet researched definition and URL link) DESCRIBE THE RELEVANCE OF THE RESEARCHED TERM TO YOUR OWN PRODUCTIO N PRACTICE? SOUND DESIGN METHODOLOG Y Foley Artistry Foley is the reproduction of everyday sound effects that are added to film, video, and other mediums in post-production to enhance audio quality http://en.wikipedia.org/wiki/Foley_(filmmaking) Sound Libraries A sample library is a collection of digital sound recordings, known as samples, for use by composers http://en.wikipedia.org/wiki/Sample_library SOUND FILE FORMATS Uncompresse d Uncompressed video, also called Clean HDMI, is digital video information that has not been compressed, or was not processed with compression on it when the video was captured directly via video capture (e.g. from a digital camera. http://en.wikipedia.org/wiki/Uncompressed_video .wav The format for storing sound in files developed jointly by Microsoft and IBM. http://www.webopedia.com/TERM/W/WAV.html .aiff AIFF is short for Audio Interchange File Format, which is an audio format initially created by Apple Computer for storing and transmitting high-quality sampled audio data. http://www.abyssmedia.com/formats/aiff-format.shtml .au .au is the Internet country code top-level domain (ccTLD) forAustralia. http://en.wikipedia.org/wiki/.au .smp (Symmetric MultiProcessing) A multiprocessing architecture in which multiple CPUs, residing in one cabinet, share the same memory. SMP systems provide scalability. As business increases, additional CPUs can be added to absorb the increased transaction volume. http://www.pcmag.com/encyclopedia/term/51559/smp Lossy Compression Lossy file compression results in lost data and quality from the original version. 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 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. http://en.wikipedia.org/wiki/MP3 AUDIO Sound The SPU is the unit responsible for all aural capabilities of the
  • 2. LIMITATIONS Processor Unit (SPU) psx. It handles 24 voices, has a 512kb sound buffer, and has ADSR envelope filters for each voice and lots of other features. http://psx.rules.org/spu.txt Digital Sound Processor (DSP) A Digital Signal Processor, or DSP, is a specialized microprocessor that has an architecture which is optimized for the fast operational needs of digital signal processing. A Digital Signal Processor (DSP) can process data in real time, making it ideal for applications that can’t tolerate delays. http://www.futureelectronics.com/en/microprocessors/digit al-signal-processors.aspx Random Access Memory (RAM) AM (pronounced ramm) is an acronym for random accessmemory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers. http://www.webopedia.com/TERM/R/RAM.html Mono Audio Monaural or monophonic sound reproduction (often shortened tomono) is single-channel. Typically there is only one microphone, one loud speaker, or (in the case of headphones and multiple loudspeakers) channels are fed from a common signal path. http://en.wikipedia.org/wiki/Monaural 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 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 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. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. http://en.wikipedia.org/wiki/Pulse-code_modulation AUDIO RECORDING SYSTEMS Analogue Analog device is usually a combination of both analog machine and analog media that can together measure, record, or reproduce (emit[disambiguation needed]) continuous information, for example, the almost infinite number of grades of transparency, voltage, resistance, rotation, or pressure. In theory, the continuous information (also analog signal) has an infinite number of possible values with the only limitation on resolution being the accuracy of the analog device. http://en.wikipedia.org/wiki/Analog_device Digital Mini Disc The MiniDisc (MD) is an obsolete magneto-optical disc-based data storage device for 74 minutes and, later, 80 minutes, of
  • 3. digitized audio or 1 gigabyte of Hi-MD data. The Sony brand audio players were on the market from September 1992 until March 2013.[1] http://en.wikipedia.org/wiki/MiniDisc Compact Disc (CD) Stands for "Compact Disc." CDs are circular discs that are 4.75 in (12 cm) in diameter. The CD standard was proposed by Sony and Philips in 1980 and the technology was introduced to the U.S. market in 1983. CDs can hold up to 700 MB of data or 80 minutes of audio. The data on a CD is stored as small notches on the disc and is read by a laser from an optical drive. The drives translate the notches (which represent 1's and 0's) into usable data. http://www.techterms.com/definition/cd Digital Audio Tape (DAT) Acronym for digital audio tape, a type of magnetic tape that uses a scheme called helical scan to record data. A DAT cartridge is slightly larger than a credit card in width and height and contains a magnetic tape that can hold from 2 to 24 gigabytes of data. It can support data transfer rates of about 2 MBps. Like other types of tapes, DATs are sequential- access media. http://www.webopedia.com/TERM/D/DAT.html MIDI Stands for "Musical Instrument Digital Interface." It is a connectivity standard that musicians use to hook together musical instruments (such as keyboards and synthesizers) and computer equipment. Using MIDI, a musician can easily create and edit digital music tracks. The MIDI system records the notes played, the length of the notes, the dynamics (volume alterations), the tempo, the instrument being played, and hundreds of other parameters, called control changes. http://www.techterms.com/definition/midi Software Sequencers An electronic device or software program that can be instructed to order and modify digitally stored musical sounds for playback, as through a synthesizer. http://www.thefreedictionary.com/sequencer 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, the QuickTime Player, and the Java plug-in, which can launch a user-activated Java applet on a web page to its execution a local Java virtual machine. http://en.wikipedia.org/wiki/Plug-in_(computing) 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. This could also be a personal computer running software such as a digital audio workstation (DAW) that listens to and sends MIDI information to other MIDI devices connected by cable or running internal to the personal computer system. The basic MIDI keyboard does not produce sound. http://en.wikipedia.org/wiki/MIDI_keyboard AUDIO SAMPLING File Size Constraints - Bit-depth In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. Examples of bit depth include Compact Disc Digital Audio, which uses 16 bits per sample, and DVD-Audio and Blu-ray Disc which can support up to 24 bits per sample.
  • 4. http://en.wikipedia.org/wiki/Audio_bit_depth 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). http://en.wikipedia.org/wiki/Sampling_(signal_processing)
