Music & Audio Advice FREE Music & Audio Advice Compression and Dynamic Range Questions and Answers 2

Question 1

What does the 'knee' setting on a compressor control?

Accepted Answer

How gradually the compressor transitions from uncompressed to compressed signal

Answer

The knee setting determines whether compression engages abruptly (hard knee) or gradually (soft knee) as the signal approaches the threshold.

Question 2

In parallel compression, what is blended with the compressed signal?

Accepted Answer

The original uncompressed signal

Answer

Parallel compression mixes the dry, uncompressed signal with a heavily compressed copy to retain transients while adding sustain and density.

Question 3

What is the typical dynamic range of a commercial pop recording after mastering?

Accepted Answer

6-10 dB

Answer

Modern commercial pop masters typically have a dynamic range of about 6-10 dB due to heavy compression and limiting during the mastering process.

Question 4

What happens when you set a compressor's ratio to infinity:1?

Accepted Answer

It functions as a limiter, preventing signal from exceeding the threshold

Answer

An infinity-to-one ratio means no signal passes above the threshold, which is the defining behavior of a brick-wall limiter.

Question 5

Which parameter would you adjust to prevent a compressor from clamping down on every drum transient in a mix bus?

Accepted Answer

Increase the attack time

Answer

A slower attack time allows the initial transient of each drum hit to pass through before the compressor engages, preserving punch and impact.
