EQ Flashcards
(11 cards)
What are the axis of an EQ graph?
X-axis = Freq / Hz
Y-axis = Gain / Amp (dB)
What does the centre line mean on an EQ graph?
0 dB
What is a high shelf boost?
A boost in the high frequencies.
What does the direction of the slope mean for the frequencies?
The frequencies in the direction of the slope are being cut.
e.g. slope going towards lows, lows are being cut.
What is resonance?
A boost in volume where the cutoff point is.
What is the slope of an EQ graph measured in?
dB per octave
What is semi-parametric EQ
Has a fixed ‘Q’ so can only alter around a fixed width.
What is parametric / band EQ?
You can alter the gain, centre frequency / cutoff, and ‘Q’.
What is the centre frequency for BPFs?
Frequency at which a BPF allows frequencies to pass through.
What is ‘Q’ on an EQ graph?
Width of band that you’re affecting.
How was EQ initially used and when?
Used to correct mic issues in the 1930s. Eventually used more creatively in the 50s-60s.
