CMP Acoustics and Recording Techniques Questions and Answers

Question 1

A producer is recording a podcast with two hosts sitting directly across from each other at a table, using a single microphone.
To capture both voices clearly while rejecting sound from the sides, which microphone polar pattern is most suitable?

Accepted Answer

Bidirectional (Figure-8)

Answer

Cardioid

Answer

Omnidirectional

Answer

Shotgun

Question 2

When recording an electric bass guitar, a producer wants to capture both the sound of the amplifier and a clean, unaffected signal simultaneously for later processing (a technique known as re-amping). What single piece of equipment is essential for splitting the bass's high-impedance signal, sending one line to the amp and another balanced, low-impedance line to the mixing console?

Accepted Answer

A DI (Direct Input) Box

Answer

A compressor with a sidechain input

Answer

A high-pass filter

Answer

A multi-pattern condenser microphone

Question 3

A vocalist is recording a track with a sensitive condenser microphone. During playback, the producer notices distracting, low-frequency 'pops' on words with hard consonants like 'p' and 'b'. What is the most common and effective tool used to prevent this issue during recording?

Accepted Answer

A pop filter

Answer

A de-esser plugin

Answer

A shock mount

Answer

A dynamic microphone

Question 4

A producer is setting up a home studio in a small, rectangular room. They notice that certain bass frequencies sound significantly louder or weaker depending on where they stand in the room. This phenomenon, caused by sound waves reflecting between parallel surfaces and combining, is known as:

Accepted Answer

Standing waves (or room modes)

Answer

Phase cancellation

Answer

The Doppler effect

Answer

Reverberation time (RT60)

Question 5

To minimize phase cancellation and comb filtering when using two microphones on two different sound sources (e.g., two separate guitar amps), which common microphone placement guideline should a producer follow?

Accepted Answer

The 3:1 rule

Answer

The inverse square law

Answer

The X/Y coincident pair technique

Answer

The 80 Hz roll-off rule

Question 6

A producer needs to record the powerful, high-SPL (Sound Pressure Level) sound of a snare drum and a loud guitar amplifier. Which type of microphone is generally best suited for these applications due to its durability and ability to handle high volumes without distortion?

Accepted Answer

Dynamic microphone

Answer

Ribbon microphone

Answer

Small-diaphragm condenser microphone

Answer

Tube condenser microphone
