A trademarked, patented technology of ElectroVoice in its microphone designs to vary the proximity effect in its microphones. Variable-D places several ports along the microphone body, each of which has a reduced level of sensitivity to higher frequencies the further they are placed from the microphone’s diaphragm.
Shorthand for “Voltage Controlled Amplifier,” an amp whose gain is affected by an external voltage fed to it.
A system of mix automation in some mixing consoles in which sound levels or other functions are altered through the use of voltage controlled amplifiers.
Several VCA faders that are fed control voltages from a group master slide. A feature in higher-end mixing boards that enables the engineer to control groupings of independent signals by a single fader that uses VCA to adjust the voltage sent to each channel.
See “Voltage Controlled Oscillator.”
In synthesizers and keyboard controllers, a MIDI message that transmits data on how hard the key was struck. Velocity messages can be used to transmit volume information, as well as triggering different samples on a multi-sampled instrument patch.
See “Pressure-Gradient Microphone.”
(Also called “Touch Sensitive“) A feature on a MIDI instrument such as a keyboard that transmits a MIDI velocity message depending on how hard the key is struck.
A smooth and repeated changing of the pitch up and down from the regular musical pitch, often done by singers or performed by string and wind players.
(Also called Software Instrument) One of a number of software-based synthesizers, samplers or sound samples that are stored and accessed via computer and performed by an external MIDI controller, rather than in a standalone synthesizer or module. Because of the wide versatility available from these instruments, a growing number of composers and electronic musicians are working with virtual instruments that can be stored in hard drives, rather than purchasing stacks of keyboards and modules.
A room in the recording studio that is used for recording vocals in isolation. This practice prevents bleed-through of the sounds of other instruments into the vocal microphone, and also reduces natural ambience and reverberation in the vocal recording.
An audio processing device effects device or plug-in that analyzes the characteristics of an audio signal and uses them to affect another synthesized signal. Primarily developed for the purpose of producing synthesized voice effects from human speech, a vocoder creates the characteristic robotic vocal sound or the “human synthesizer” effect that makes it sound like the synth is speaking or singing words.
1) Besides the obvious definition of the sound humans make from their mouths…in synthesizers, a voice refers to one of a number of sounds/pitches that may be played at the same time. “Monophonic” means only one voice plays at a time, while “polyphonic” means multiple voices can sound at once. (See also “Polyphonic”, “Monophonic.”) 2) In some synthesizers, like Yamaha, “voice” may also refer to a specific sound patch available on the synth.
The recording of vocal announcements or narration over a bed of music in video, film or commercials.
Computer memory whose data will will be lost when the computer is turned off. RAM (Random Access Memory) is the most common form of volatile memory.
