Sound Design Midterm

amplitude

the strength or intensity of a sound wave

frequency

rate at which any kind of motion repeats itself

hertz

measurement of frequency

wave length

determined by the frequency of the sound

sine wave

fundamental type of wave to represent a single frequency with no harmonics; building block of all sound

resonance

the act of enhancing certain frequencies of whatever is vibrating

Compression Waves

created by the movement of a speaker cone

Expansion

occurs when the cone moves inward to create a particle vacuum

Compression

Air particles rush to fill space of the particle vacuum until it expands again

Cycle

when a sound cone completes an expansion & compression

resonant frequency

The base level frequency of an object/space

harmonics

frequencies that are integer multiples of the fundamental frequency

constructive interference

The interference that occurs when two waves combine to make a wave with doubled amplitude

Complex wave

combo of the fundamental waves and harmonics

Input

anything that captures audio signal

processing

anything that changes, enhances, mimics or "corrects" an audio signal

Output

any device that transduces digital audio signal into an audible sound wave

connector

any cable that transfers data from one piece of gear to another

transducer

devices that converts energy from one form to another

Mic Level

level you get from most microphones

signal processor

device that manipulates the audio signal in a variety of ways for different applications

input gain or trim

first level of volume control

equalizer

adjusts the balance between frequencies within an audio signal

aux sends

allows you to split signal from orginal chain of your signal

monitors/signal processors

allow band members to hear parts of the mix they can't clearly hear onstage

pan

allows you to move the signal in the channel to left or right

channel fader

another level of gain control used for fine tuning

aux returns

points in the signal flow where the sent and processed signal is returned to the mix

aux master

gain control for the returned and usually processed signal

master fader

Controls the overall volume of any tracks assigned to the same output

signal processor

a device that manipulates the audio signal in a variety of ways

crossover

device that splits the audio signal into the correct frequencies

amplifiers

devices that converts electrical audio signal into mechanical energy

speaker

output device; final stage of signal flow

Reverb

echo without delay

TRS

Tip Ring Sleeve

sound

acoustic energy

condenser

picks up sound from statically charged plates

Phantom Power

Low voltage power used by Condensor Microphones

low pass filter

cuts out high end frequencies

high pass filter

cuts our low end frequencies

active speaker

does not require external power

passive speaker

requires external power

feedback

angry noise caused from high sensitivity of devices being heard in loop
