Transcript

  • 1. Effects Unit Distortion Distortion effects create "warm", "dirty" and "fuzzy" sounds by compressing the peaks of a musical instrument's sound wave and adding overtones. http://en.wikipedia.org/wiki/Distortion_(music) Talk Box A talk box is an effects unit that allows a musician to modify the sound of a musical instrument. The musician controls the modification by lip syncing, or by changing the shape of their mouth. http://en.wikipedia.org/wiki/Talk_box Bonjovi (Living On A Prayer http://www.youtube.com/watch?v=lDK9QqIzhwk Pitch Bend A smooth uninterrupted glide in passing from one tone to another, especially with the voice or a bowed stringed instrument. http://www.thefreedictionary.com/Pitch+bend Delay + Multitap Delay Delay is an audio effect which records an input signal to an audio storage medium, and then plays it back after a period of time. Multitap delayed signal may either be played back multiple times, or played back into the recording again, to create the sound of a repeating, decaying echo. http://en.wikipedia.org/wiki/Delay_(audio_effect)
  • 2. Auto tune Auto-Tune is a proprietary audio processor created by Antares Audio Technologies. Auto-Tune uses a phase vocoder to correct pitch in vocal and instrumental performances. It is used to disguise off-key inaccuracies and mistakes, and has allowed singers to perform apparently perfectly tuned vocal tracks without needing to sing in tune. http://en.wikipedia.org/wiki/Auto-Tune Example: T-pain (Bartender) http://www.youtube.com/watch?v=Lt2wjJlP2N4 Phaser A phaser is an audio signal processing technique used to filter a signal by creating a series of peaks and troughs in the frequency spectrum. The position of the peaks and troughs is typically modulated so that they vary over time, creating a sweeping effect. For this purpose, phasers usually include a low-frequency oscillator. http://en.wikipedia.org/wiki/Phaser_(effect) Temeblo An imitative sound, as of thunder or an explosion, produced artificially for theatrical purposes, as for a film, play, or radio program. Often used in the plural. http://www.thefreedictionary.com/sound+effect Vibrato Vibrato is a musical effect consisting of a regular, pulsating change of pitch. It is used to add expression to vocal and instrumental music. Vibrato is typically characterized in terms of two factors: the amount of pitch variation ("extent of vibrato") and the speed with which the pitch is varied ("rate of vibrato"). http://en.wikipedia.org/wiki/Vibrato Compression Audio compression is a form of data compression designed to reduce the transmission bandwidth requirement of digital audio streams and the storage size of audio files. Audio compression algorithms are implemented in computer software as audio codecs. http://en.wikipedia.org/wiki/Audio_compression_(data)
  • 3. Limiter A compressor or limiter is an automatic volume control that reduces the volume when the input gets too loud. Originally they were used to prevent AM radio transmitters from distorting if the announcer got too close to the microphone, and to keep volume levels consistent. Then some creative folks discovered that a compressor can sound cool as an effect on voices and musical instruments. http://www.ethanwiner.com/compressors.html Gating A Noise Gate or gate is an electronic device or software that is used to control the volume of an audio signal. In its most simple form, a noise gate allows a signal to pass through only when it is above a set threshold: the gate is 'open'. http://en.wikipedia.org/wiki/Noise_gate Surround Sound Surround sound encompasses a range of techniques such as for enriching the sound reproduction quality of an audio source with audio channels reproduced via additional, discrete speakers. http://en.wikipedia.org/wiki/Surround_sound Prince (The Beautiful Ones) http://www.youtube.com/watch?v=DijrdUoFt80 Mono-aural Commonly called mono sound, mono, or non-stereo sound, this early sound system used a single channel of audio for sound output. In monophonic sound systems, the signal sent to the sound system encodes one single stream of sound and it usually uses just one speaker. Monophonic sound is the most basic format of sound output. http://www.webopedia.com/TERM/M/monophonic_sound.html
  • 4. Stereo The term Stereophonic, commonly called stereo, sound refers to any method of sound reproduction in which an attempt is made to create an illusion of directional and audible perspective. This is usually achieved by using two or more independent audio channels through a configuration of two or more loudspeakers 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 Copyright Copyright is a legal concept, enacted by most governments, giving the creator of an original work exclusive rights to it, usually for a limited time. Generally, it is "the right to copy", but also gives the copyright holder the right to be credited for the work, to determine who may adapt the work to other forms, who may perform the work, who may financially benefit from it, and other related rights. http://en.wikipedia.org/wiki/Copyright Performing rights Performing rights are the right to perform music in public. It is part of copyright law and demands payment to the music’s composer/lyricist and publisher (with the royalties generally split 50/50 between the two). Public performance means that a musician or group who is not the copyright holder is performing a piece of music live, as opposed to the playback of a pre-recorded song. http://en.wikipedia.org/wiki/Performing_rights Licenses A license may be granted by a party ("licensor") to another party ("licensee") as an element of an agreement between those parties. A shorthand definition of a license is "an authorization (by the licensor) to use the licensed material (by the licensee)." In particular, a license may be issued by authorities, to allow an activity that would otherwise be forbidden. It may require paying a fee and/or proving a capability. The requirement may also serve to keep the authorities informed on a type of activity, and to give them the opportunity to set conditions and limitations. https://en.wikipedia.org/wiki/License Contract A contract is an agreement having a lawful object entered into voluntarily by two or more parties, each of whom intends to create one or more legal obligations between them.
