The time it takes for a processor to react to a signal above the threshold.
What is BandWidth
Is the range of frequencies around the center frequency of an equalizing filter that will be affected.
What is Breathing
This is a property/effect created by a compressor when the release is set incorrectly. Breathing is noticed when, due to a slow return (release) to operating level, there is a very noticeable rise of the noise floor.
What is a Compressor
a dynamic processor that makes loud sounds softer and makes soft sounds louder. They also increase the audible level of the noise floor and limit the overall dynamic range of the audio being processed.
What is a De-Esser
A compressor that reacts to a selected range of frequencies, usually used to reduce the sibilant frequencies of a vocal/voiceover track.
What is a Equalizer
A processor that allows for the intentional altering of the frequency characteristics of an audio signal.
What is an Expander
A processor that allows for the increase of the dynamic range of the audio signal that is being processed.
What is a Field Effect Transistor
A Transistor where the voltage varies the size of the signal stream and enhances even order harmonics.
What is Make-Up Gain
The parameter on a compressor to increase the output of the unit after dynamic reduction has been applied.
What is a Gate/Noise Gate
A processor designed to reduce the noise floor in an audio signal.
What is the definition of Hold
Is a parameter on a gate that determines how long the gate is held open before the onset of attenuation begins (this is when the gate starts to close).
What is the Key Input
Is an additional input back into a gate that is used to control when the gate opens.
What is the definition of Knee
a parameter on a compressor that determines when the compressor starts working. With a hard knee setting the knee and threshold are the same value. With a soft knee setting the compression will begin slightly below the threshold and gradually transition to slightly above the threshold.
What is a Leveling Amplifier
A compressor with a medium attack time, a medium to slow release time, a high ratio setting and low threshold. This type of unit is constantly in gain reduction. (Example: Universal Audio LA 2A)
What are Mic Pre-Amplifiers
A circuit (the first stage of recording console or a standalone device) that raises the output of a microphone to line level.
What is a Peak Limiter
A compressors that have a fast attack time and a medium to fast release time with a high ratio setting, usually 10:1 and higher, and a high threshold. (Example: UREI/Universal Audio 1176)
What is Pumping
This is a property/effect created by a compressor when the setting are such that you detect a sudden and usually unwanted, deep gain reduction by the compressor.
What is Range
Is a parameter on a gate that determines the amount of attenuation when the gate is closed.
What is Ratio
A parameter on a dynamic processor that sets the relationship between input and output levels.
What is the definition of Release
A parameter that determines how long the compressor will take to return to nominal after compression.
What is the definition of Release for a Gate
A parameter that sets the amount of time it takes for the gate to close once the Hold time has elapsed.
What is a Side-Chain
Is an additional input into a compressor that is used to control when the compressor changes from a unity gain amplifier to a compressor.
What is the Threshold
A parameter on a dynamics processor that determines when the processor begins to work.
Comb Filtering: The cancelation and/or reinforcement at different frequencies, which is dependant on the amount phase shift/delay.
Convolution Reverb: Is a process for digitally simulating the reverberation of a physical or virtual space. This process is based on the mathematical convolution operation that uses a pre-‐recorded audio sample of the impulse (I.R.) of the space being modeled.
Delays: A devise that delays a signal emulating reflections/echos.
Delay Time: Is the length of time between the original signal and when the initial repeat is heard.
Depth: Is a parameter that determines the distance the repeated delay time drifts away from the original delay time.
Diffusion: Is a parameter on a reverb that emulates objects within a room.
Doppler Effect: The perceived increase in pitch of a sound as it moves closer to the listener. Also the pitch will decrease as the sound moves away from the listener.
Early Reflections: A parameter setting in a reverb that allows the user to control the reflections of sound off of nearby surfaces.
Feedback: A setting on a delay unit that allows for the delayed signal to return to the input of the unit, thus creating a controlled feedback loop. This will allow the user to create repeats of the original signal
Pre-Delay: A parameter that sets the time between the original signal and when the reverb begins.
Pre-Echo: Is a parameter on a reverb that emulates the first reflections of nearby boundaries. (See Early Reflections)
Reverb Time: A parameter on a reverb that determines the length of time it takes for sound/acoustic energy to decay within a space.
