Everything I have up to 1/31/23 Flashcards
oscillation
movement back and forth at a regular speed
Pitch
the quality of a sound governed by the rate of vibrations producing it; the degree of highness and lowness of a tone
Timbre
Generally refers to the quality of a sound by a particular voice or instrument; Timbre is useful in being distinct from pitch, intensity and loudness as a descriptor of sound. Harmonies help shape an instruments timbre.
Formants
Are frequency peaks in the spectrum which have a high degree of energy. Formant Frequencies are essentially resonance frequencies of a vocal track. These frequencies vary among different persons and words.

Gain
Relates to a signals strength/measurment of amp.
Volume
Amount of space that a substance/object occupies. Informally used as a measurement of sound/degree of loudness.
(how much air is being moved)
What does FET stand for?
field effect transducer
Hertz
cycles per second
Reverb
sound of reflections off walls
What frequencies are humans most sensitive to?
1-5 kHz
but we hear
3.5 kHz best
Sample Rate
The process of taking discrete readings of a signal at various moments in time. Each sample is a snapshot of the signal at a particular instant.
Consumer Line Level
-10dBv
Pro Line Level
+4dBu
Bit Depth
Quantizes Amplitude
Higher bit depth means?
Greater Dynamic Range
Quantization
This means each sample is assigned to the closest available value.
Waveforms in audio are broken down into 7 fundamental characteristics, what are they?
Frequency
Amplitude
Velocity
Envelope
Wavelength
Phase
Harmonic Content
What are the 2 MOST fundamental parts of waveforms?
Amplitude and Frequency
How is amplitude perceived to the human ear?
as the LOUDNESS of something
What are the common construction techniques used in studio design?
Floated Floors
Double Walls
Isolation Booth
Double Windows and Doors
Hanging ceilings*
What is the goal of room design?
To have a room with a flat frequency response without adding its own sound.
What is the spreading or scattering of sound waves called?
Diffusion
In audio what is 48v and what is it used for?
48v is Phantom Power
it is used to power your mic
What is a device called that changes one form of energy to another corresponding form of energy?
Transducer
What is the principle in which dynamic and ribbon mics generate an electric current?
Magnetic Induction
What are the 3 most common polar patterns?
Omni
Cardioid
Bi-Directional
Describe how the 3 most common polar patterns are drawn on a graph.
Omni is a circle
Cardioid is heart shaped
Bi-Directional is a figure 8
What are 3 balanced connectors used in studios?
XLR
TRS
Define proximity effect
effect that causes an increase in bass response whenever a directional mic is brought within a foot of a sound source.
simple: closer mic get more bass response
what is the human range of hear in regards to amplitude dynamic range?
0 - 120dB
120dB=PAIN
SPL stands for?
Sound Pressure Level
Frequency is perceived as?
PITCH
if frequency changes then so does pitch
Directional polar response
More responsive to sounds coming from a certain direction.
