midterm Flashcards
frequency
the number of complete cycles of a repetitive waveform that occurs in one second
dBFS
a dB reference level equal to “full scale” or “Full code”
full scale
refers to the maximum voltage level possible before “digital clipping”
- responds in a fashion very similar to how human ears perceive loudness
- decibel scale
- originally designed for broadcast and recording
VU meter (dBu)
dBspl
local pressure deviation from the ambient atmospheric pressure, caused by a sound wave
bit rate
- bit depth
- number of data bits replayed or transferred in a given period of time
fidelity
the degree of “accuracy” of a recording or sound reproduction
high fidelity
a signal that is transmitted with full range and very low distortion
loFi music
- low fidelity
- music or production quality in which elements usually regarded as imperfections of a recording or performance are audible, sometimes as an aesthetic choice
Direct Drive turntable
- one of the three main phonograph designs currently being produced
- directly turned the table with the motor
Belt drive turntable
- one of the three main phonograph designs currently being produced
- belt connected to a motor turns the table
stylus
stylus is a phonograph or gramophone needle used to play back sound on gramophone records, as well as to record the sound indentations on the master record
rpm
revolutions per minute
digitization
taking a tangible object (analog) and turning it into a computer file(digital)
audio restoration
generalized term for the process of removing imperfections from sound recordings
preservation copy
digital original that all other derivatives are copied from
work copy
for audio editing or restoriation
access copy
for ordinary playback and distribution
adobe waveform editor
displays the continuous wave form of the sound
adobe multitrack editor
displays multiple tracks at one time for editing
adobe spectral frequency view
displays the spectral view of the track for editing
adobe metadata editor
displays the categories for entering metadata information
- has two plates with a voltage between them
- one of the plates is made of very light material and acts as the diaphragm
- the diaphragm vibrates when struck by sound waves, changing the distance between the two plates
condenser (capacitor) microphone
- consisting of a coil of wire attached to a thin, lightweight diaphragm that vibrates in response to sound
- the coil in turn vibrates within the field of the magnet and a signal is generated in proportion to the acoustic vibration the mic receives
dynamic microphone
omnidirectional
equally sensitive to sound from all directions, having no specific directionality
cardioid
has maximum sensitivity from the front, less sensitivity from the sides, and minimal sensitivity from the back of the diaphragm
hyper-cardioid
has focused sensitivity from the front, but sound from the rear is not suppressed quite as mcuh
A/B technique
spacing a pair of cardioid or omnidirectional microphones apart in such a way that they cover the space but do not create phase issues for each other
(. | | )
XY technique
two cardioid microphones of the same type and manufacture with the two mic capsules wither as close as possible or within 12 inches of each other
( X )
ORTF technique
two cardioid microphones with a spacing of 17 sm between the microphone diaphragms and with an 110 degree angle between capsules

podcast
- combination of the words iPod and broadcast
- an audio or video, delivered via the internet
reasons to podcast
- direct info dissemination to an audience or consumer
- business/product promotion and branding
- people love free content
- alternative income: advertisements, patreon
best practices fo podcasting
- nail your brand and know your audience
- good audio quality
- research your guest
- good intro technique
- promote your guest and their “product” at the beginning
