FREE Music & Audio Advice Microphone Placement Techniques Questions and Answers

Question 1

When recording a source with two microphones, what is the primary purpose of the 3:1 rule?

Accepted Answer

To minimize phase cancellation and comb filtering between the microphones.

Answer

To ensure the microphones are equidistant from the source for a balanced stereo image.

Answer

To increase the proximity effect for a warmer, bass-heavy sound.

Answer

To position the microphones at a 90-degree angle for a coincident pair setup.

Question 2

An audio engineer is setting up a Blumlein pair to record a string quartet. Which of the following microphone configurations is correct for this technique?

Accepted Answer

Two bidirectional (figure-8) microphones with their capsules coincident and angled 90 degrees apart.

Answer

Two omnidirectional microphones spaced 3 to 10 feet apart.

Answer

Two cardioid microphones with their capsules placed as close as possible at a 90-degree angle.

Answer

Two cardioid microphones spaced 17 cm apart at a 110-degree angle.

Question 3

What are the standard specifications for the ORTF stereo microphone technique?

Accepted Answer

Two cardioid mics at a 110-degree angle, capsules spaced 17 cm apart.

Answer

Two bidirectional mics at 90 degrees, capsules coincident.

Answer

Two cardioid mics at 90 degrees, capsules coincident.

Answer

Two omnidirectional mics spaced 30 cm apart, parallel to each other.

Question 4

A recording engineer notices that a close-miked male vocal track sounds overly bassy and 'muddy'. Which microphone phenomenon is the most likely cause?

Accepted Answer

Proximity Effect

Answer

The 3:1 Rule

Answer

Phase Cancellation

Answer

Comb Filtering

Question 5

When using a coincident pair (X/Y) technique to record an acoustic guitar, what is the primary advantage regarding phase?

Accepted Answer

It minimizes phase issues because the capsules are as close as possible.

Answer

It maximizes phase differences to create a wide stereo image.

Answer

It intentionally creates phase cancellation to filter out unwanted frequencies.

Answer

It requires a third microphone to correct phase alignment.

Question 6

An engineer wants to capture the overall sound of a drum kit, including the cymbals and a balanced image of the tom-toms and snare. They decide to use a spaced pair (A/B) of overhead microphones. To keep the snare drum centered in the stereo image, what is a critical placement consideration?

Accepted Answer

Using one omnidirectional and one cardioid microphone.

Answer

Placing the microphones as far apart as possible to maximize stereo width.

Answer

Angling both microphones directly at the kick drum beater.

Answer

Ensuring both microphones are equidistant from the center of the snare drum.
