PHYSICS OF SOUND
When sound waves add up to a decreased amplitude, quieter, thinner sound
What is destructive interference?
The perceived “tone colour” or “tone quality” of a complex sound
What is timbre?
This part of the ear acts as a “funnel” to the middle ear.
What is the pinna?
The device used to convert a continuous audio voltage signal into a discrete/binary one.
What is an Analog to Digital Converter (ADC)?
A connector used to attach unbalanced cables to electric musical instruments.
What is a 1/4" TS (tip, sleeve) connector?
What is amplitude?
These 4 characteristics refer to a sound’s “envelope”
What is Attack, Decay, Sustain, Release?
The membrane that separates the outer and middle ear.
What is the ear drum?
Sound data that is represented by a continuous voltage.
What is analog audio?
The component of a mixer that receives incoming signal & allows for level adjustment, EQ processing, and sending.
What is a channel strip?
A zone of low pressure in a sound wave
What is a rarefaction?
Any resonant frequency of a sound above the fundamental
What is an overtone?
The three bones in the middle ear also known as "ossicles".
What are the Malleus (aka hammer), Incus (aka anvil) and Stapes (aka stirrup)?
The idea that we must sample at 2x the highest frequency we want to capture/reproduce
What is Nyquist’s Sampling Theorem?
A type of cable with 3 conductors (not looking for the connector name, just cable name).
What is a balanced cable OR stereo unbalanced cable?
Number of complete waves passing a fixed point in a given amount of time
What is frequency?
Any component of a frequency spectrum that does not proportionally relate to the fundamental
What is an inharmonic overtone?
The sound of ringing, whistling or buzzing in the ears when there is no external stimulus
What is tinnitus?
These are 3 examples of analog audio devices and their storage mediums.
What are phonograph & cylinder, gramophone & disc, turntable & vinyl, reel-to-reel & tape, 8-track player & cart, cassette player & cassette.
A mixer feature that is useful for adding reverb or creating headphone mixes.
What is a send?
Type of wave in which the vibration the of the medium is parallel to the direction the wave travels
What is a longitudinal wave?
Periodic changes in the pitch of a tone
What is vibrato?
The way humans can tell what direction sound is coming from. Includes: Interaural Time Difference, Interaural Level Difference, and Head-Related Transfer Function
What are binaural cues?
The 2 factors that determine the quality of digital audio.
What are sample rate and bit depth?
A cable capable of transferring 8 simultaneous digital audio channels at 44.1kHz
What is an ADAT cable?
