Microphones
This polar pattern picks up in all directions.
What is omnidirectional?
We perceive this as pitch in sound.
What is frequency?
This equipment is used to add voltage to microphones, control volume of mix, route signals to monitors or effects, and manipulate the signals with EQ.
What is a mixer?!
The perception of sound seemingly in the middle of two speakers.
What is phantom image?
This stereo miking technique is also called "coincident".
What is XY?
This type of microphone works by electromagnetic induction, and contains both a diaphragm and coil of wire.
What is a dynamic microphone?
This is the unit in which we measure amplitude.
What are decibels?
Where a fader should be set to when setting levels on a microphone.
What is unity (or zero).
When two sound waves are in phase with each other and add together.
What is constructive interference?
This stereo miking technique can be referred to as A/B, or this other term.
What is spaced pair?
An SM58 dynamic microphone has this polar pattern, named for it's "heart" shape.
What is cardioid?
The range of human hearing.
What is 20hz-20khz?
Vocal --> Mic --> Mixer -->Speaker
Please describe the transfer of energy happening in the above diagram. Describe the type of energy and the "level" ie microphone level.
What is acoustic energy (mic level)to electrical energy(mic level) to line level to speaker level.
This chamber has no room reflections and is used to measure and test sound equipment... or to drive you crazy.
What is an anechoic chamber?
Use one of these boxes to convert a line-level, unbalanced source to a mic level, balanced source.
What is a DI box.
This microphone is best for picking up higher frequencies , and requires power to work.
What is a condenser microphone?
When the frequency decreases, the length of this increases.
What is wavelength?
This filter cuts off low frequencies on your signal.
What is a high pass filter?
The point at which the direct sound coming from an instrument is equal to the room sound.
Hint - elephant ears.
What is critical distance?
Two tools we use to create depth in our stereo image.
What are pan and reverb?
The phenomena that occurs in directional microphones, where low frequencies are enhanced as you move closer to the microphone.
What is proximity effect?
This is the equation we use to measure wavelength.
What is Wavelength = Speed of Sound/Frequency?
XLR cables and TRS cables are examples of these, which work through common mode rejection.
What are balanced cables?
This is also known as phase cancelling.
What is destructive interference?
This stereo miking technique is named after a French radio company and is also called semi-coincident.
What is ORTF?
