Audio Recording 1 Quiz 3

transducer

first in recording chain, converts the acoustic sound into electrical sound

Large Diaphragm microphones

Best for vocals, drums, and anything that you would want a bigger more full sound for

Small Diaphragm microphones

are used to isolate a particular area of a sound source, like the bridge of a guitar or string

Emile Berliner

Invented the Gramophone, invented acoustic tiles

The types of microphones?

Condenser, Dynamic, Ribbon

condenser microphone

has a fixed backplate, NEEDS +48 OF PHANTOM POWER, and this current charges, and the space created in between is the frequency of the sound

good for higher frequencies like vocals and cymbals

Dynamic Microphone

is moved by a metal coil, which creates voltage around the diaphragm, handling a higher SPL and more durable

Example of Dynamic Microphone

Shure SM57 and SM58

Ribbon Microphones

form of a dynamic microphone, but holds a METAL RIBBON inside a U-shaped magnet, and as the ribbon moves it creates the electrical signal

used for warm vocals, or guitars, for that vintage colorful sound

Polar pickup patterns

the polar patterns of a mic with show how it will pick up sound

omnidirectional

picks up from all angles of the microphone

cardioid microphone

only one side

bidirectional

picks up sound in two usually opposite directions

shotgun

picks up directly infront

Mic Cable, what is it made of

it has the pins in the cable, one hot and cold signal, and third one is a ground

The lower the frequency the more---

onmidirectional it is

the higher the frequency the more ---

cardioid

Proximity effect

the closer you are to the source, the more of a boost you will get of beta frequencies, usually in cardioid

condensers usually have a flatter freq. response

Shure SM57 is really good for

vocals, clear and crisp, didn't capture lower frequencies as good

Audix D2 is better for

more mid to lower frequencies, is a dynamic

Microphone stands 1

Short tall

Mic stand 2

boom

mic stand 3

telescoping arms

mis stand 4

tripod/round

mic stand 5

isolation

Pop filter

designed to soften and disperse air plosives

Wind Screen

same as pop filter, but eliminate wind and outside noises

Close miking how to position

less than three inches away from the source of the sound, which creates a tight sound quality while eliminating any outside acoustic sound from being picked up

3:1 miking rule

To reduce leakage and maintain phase integrity, for every unit of distance between the original mic and sound source, the second mic should be separated by at least 3 times that distance

How to separate instrument's and eliminate bleed in a room

use gobos and distance

Proximity effect

lower frequencies get boosted the closer it gets, you get a boomier sound

distant miking

placing a mic further from the source can pick up a large amount of the sound such as an ensemble thereby preserving the overall tone balance, allowing for the acoustics of the room to be picked up more clearly

stereo miking techniques

using two mics that can be panned to capture a full sound

spaced pair

two mics placed a certain distance apart, left right fashion, overheads for drums, piano, choir, or small ensemble acoustic guitars

XY stereo tech

two matched cardioid mics placed coincidently (diaphrams close together) with grills almost touching but facing in opposite directions between a 90 and 135 degree angle- capturing a certain space

ORTF

After french radio organization, it uses two matched cardioid microphones with a spacing of 17 cm between the microphone diagphrams, and with a 110 angle between the caples, emulates the REAL HUMAN EAR DISTANCE

Blemein Pair

TWO BIDIRECIONAL MICS placed coincidently at a 90 degree angle to achieve a stero field between them

Mid/Side

A pair of one cardioid and one bi directions mic. The cardioid is the mid placed forward towards the source picks up direct sound. The bidirectional microphone is placed sideways coincidentally

Mid side more about it...

One of those duplicate signals need to be slightly out of phase, and go to audiosuite—invert. The need to be panned or they will cancel out

Decca tree

hese are used for very large ensembles, using 3 omnidirctional microphones, to get as wide as possible of a recording setting two microphones 6 feet apar with a center mic placed 3 feet infron

What microphone was used for vocal tracking

Telefunken AK47

What mic was used for room

Audio Technica 4050

Mic used for kick

Shure Beta 91 and 52
