Understanding & Applying Frequency Graphs

Question 1

Some occasions where you would use a frequency graph

Answer 1

EQ
Multiband compressor
Microphone frequency response

Question 2

What’s on each axis of a frequency graph?

Answer 2

X-axis: Frequency (Hz)
Y-axis: Volume (dB)

Question 3

What’s different about how frequency graphs are written?

Answer 3

They’re logarithmic (Non-linear)
As they increase in power of 10s

Question 4

Large diaphragm condenser

Answer 4

High pass filter
Slight high end boost

Question 5

Dynamic

Answer 5

Good low end frequency
Brightens up the high end without the muddy mid frequencies

Question 6

Ribbon

Answer 6

Pretty much a flat line with a slight high end cut off

Question 7

Comparing AKG C414 and Audit D6 on the woofer

Answer 7

Both similar
More low end with little high end

Question 8

Tweeter

Answer 8

C414-Some low end, mid frequencies cut off, high end boost
D6-Little low end with mid frequencies cut off, more high end boost

Question 9

Full range-On axis

Answer 9

Better representation of the 2 mic’s frequency response
C414-A flat line
D6-More high end with a slight mid frequency cut off

Question 10

Full range-Off axis

Answer 10

C414-Same as on axis
D6-A bit more low end boost, meaning that the change of position can have an impact on the frequency response of a dynamic microphone
