Microphones and Sound Recording
Terms in this set (57)
The method by which a microphone transforms sound waves into electrical energy that is analogous with frequency, waveform, and amplitude.
Moving coil microphone; when sound waves strike the diaphragm of a microphone and move its coil and electrical signal is produced. A magnet produces a magnetic field which surround the coil, and motion of the coil within this field causes current to flow. Very rugged, does NOT require an outside power source.
Its diaphragm consists of a light flexible membrane that vibrates with sound pressure towards a fixed back plate. The diaphragm is mounted close to, but not touching, a rigid back plate. Not as rugged and requires an outside power source. Gives a very flat frequency response.
Changes sound into electricity by the use of a thin metal strip suspended in a magnetic field that picks up the vibration and turns it into a signal by magnetic induction. Fragile and much less common type of transducer, they don't require outside power, but can be damaged if power is fed into them.
Lavelier Microphone (Lav)
a small electret or Ribbon diaphragm used for television, theatre, and public speaking applications in order to allow for hands-free operation
picks up sound from the front and back but not the sides
Slightly narrower pickup pattern than cardioid with slight rear pickup pattern.
A type of hyper cardioid microphone with several parallel tubes of different lengths in front of the diaphragm to enhance its directional focus.
a telescoping tube that a directional mic is mounted to so it can be positioned just out of the camera shot
measure of the range of frequencies a microphone can hear and reproduce
Three-pin plug for three-conductor "balanced" audio cables employed with high-quality microphones, mixers, and other audio equipment.
cables that allows you to connect the analogue audio outputs of components such as your CD player, radio tuner, pre-amplifier, DAC and television to your amplifier and receiver.
Dynamic microphone advantages/uses
Sturdy, tough, don't need electricity, and less expensive than condenser mics. Great for recording loud sounds (drums and electric-guitar amplifiers).
More sensitive to sound, can detect a higher range of frequencies, less rugged, more expensive, requires phantom power (+48v)
The sounds of a given location or space.
Created when a sound or signal is reflected causing a large number of reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space.
X-Y stereo pair
Stereo mic technique where two directional microphones are placed at 90° to each other facing the sound source
Stereo mic technique that employs a bidirectional microphone (with a Figure of 8 polar pattern) facing sideways and a cardioid facing the sound source.
Stereo mic technique that uses two cardioid or omni directional microphones spaced 3 - 10 feet apart from each other panned in left/right configuration to capture the stereo image of an ensemble or instrument.
Stereo mic technique that uses two cardioid microphones spread to a 110° angle. Simulates the position of human ears.
A microphone is placed relatively close to an instrument or sound source, within three to twelve inches, producing a dry or non-reverberant sound.
A microphone — typically a sensitive one — is placed at some distance from the sound source. The goal of this technique is to get a broader, natural mix of the sound source or sources, along with ambient sound, including reverberation from the room or hall.
A technique used in audio recording, whereby a performer listens to an existing recorded performance (usually through headphones in a recording studio) and simultaneously plays a new performance along with it, which is also recorded.
An audio recording technique in which a performer sings or plays along with their own prerecorded performance, usually to produce a stronger or "bigger" sound than can be obtained with a single voice or instrument.
A method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole.
Science of sound; quality that makes a room easy or hard to hear in
Direct input (DI)
Recording sound directly from the instruments output to the DAW input without amplification. Bass guitar is often recorded this way.
variations in air pressure resulting from the vibrations of material objects.
unit of measure for the loudness of a sound
the intensity of sound, perceived as loudness.
perceived as the sound's pitch (high or low)
a microphone pick up pattern that is sensitive to sound from all directions
a microphone pick up pattern that is sensitive to sound from only one direction (shotgun mic).
a microphone pick up pattern that is sensitive to sound from the front and somewhat to the sides
Disadvantages of a microphone with a condensor transducer
1) requires the use of an outside power source (a battery or phantom power) 2)NOT very durable
the directions in which a microphone is most sensitive to sound
DAW(Digital Audio Workstation)
an electronic device or computer software application for recording, editing and producing audio files such as songs, musical pieces, human speech or sound effects (Pro Tools).
the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies when placed very close to a sound source. Omni-directional pick up patterns do NOT exhibit this effect.
1/4 inch TS (tip-sleeve) phone
type of connector used for electric guitars, headphones, and amp (and SOME microphones, but not recommended)
1/8 (3.5mm) TS mini phone
type of connector used for connecting headphones to portable devices, such as cell phones.
Steps in the music recording process
3 to 1 rule
when using two microphones to record a source, normally you will get the best results(least phase issues) by placing the second mic three times the distance from the first mic that the first mic is from the source
common lossless audio container format used on Windows operating system that can be converted to and from AIFF without degradation of quality. Used to record audio for use in DAWs.
MPEG 1 Audio Layer 3, the most common lossy audio codec today, used for sound on the web due to its small file size

(AKA- figure 8 pickup pattern, pick up sound from the front/back)
Primary Use: mid-side stereo miking technique where you are miking a room or space, acoustic guitar
Large Diaphragm Condenser
Primary Use: Vocals, acoustic instruments, overheads for drum kit
Primary Use: LIVE Vocals
The space between a nominal signal (in this case, line level) and the point where the circuit fails or distorts/clips. In digital, basically anything under 0 dB would be considered headroom.
Ideal recording levels
peaks between -12 and -6
