Question 1

What is the primary purpose of a diffuser panel in a recording studio?

Accepted Answer

Scatter sound waves to reduce flutter echo

Answer

Diffusers scatter sound waves in multiple directions, breaking up flutter echo and standing waves without deadening the room.

Question 2

Which microphone pattern is best for isolating a single instrument on a loud stage while rejecting side bleed?

Accepted Answer

Hypercardioid

Answer

Hypercardioid patterns have the narrowest front pickup lobe and strong rear rejection, making them ideal for high-isolation scenarios.

Question 3

What does 'critical distance' refer to in room acoustics?

Accepted Answer

The point where direct and reverberant sound levels are equal

Answer

Critical distance is where the direct sound field and the reverberant field have equal energy, influencing microphone placement decisions.

Question 4

A recording engineer notices a 'comb filtering' artifact in a guitar track. What most likely caused it?

Accepted Answer

Two slightly delayed versions of the same signal being combined

Answer

Comb filtering results from mixing a signal with a slightly delayed copy of itself, creating alternating peaks and notches across the frequency spectrum.

Question 5

What is the recommended sample rate for recording audio intended for high-resolution music distribution?

Accepted Answer

88.2 or 96 kHz

Answer

88.2 kHz or 96 kHz are standard high-resolution sample rates that capture extended frequency content beyond CD quality for premium distribution.
