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

Question 1

An audio engineer wants to make a bass guitar part more present and powerful without sacrificing the punch of its initial transients.
They decide to blend the original, unprocessed bass track with a heavily compressed version of the same track.
What is this technique called?

Accepted Answer

Parallel Compression

Answer

Sidechain Compression

Answer

Upward Expansion

Answer

Serial Compression

Question 2

Which of the following best defines 'dynamic range' in the context of an audio recording?

Accepted Answer

The difference in decibels between the loudest possible undistorted peak and the noise floor.

Answer

The average loudness level of the entire track, measured in LUFS.

Answer

The frequency response of the recording, from the lowest to the highest audible frequency.

Answer

The ratio of the input signal to the output signal of a compressor.

Question 3

A producer is mixing an electronic dance track and wants the synth pad to rhythmically decrease in volume every time the kick drum hits, creating a characteristic 'pumping' effect. Which compression technique is most suitable for this task?

Accepted Answer

Sidechain Compression

Answer

Multiband Compression

Answer

Parallel Compression

Answer

Upward Compression

Question 4

In a standard downward compressor, what is the function of the 'Threshold' parameter?

Accepted Answer

It sets the decibel level at which the compressor begins to apply gain reduction.

Answer

It determines how much the signal is reduced once compression starts.

Answer

It controls how quickly the compressor stops applying gain reduction after the signal falls below the set level.

Answer

It adjusts the overall output volume after the signal has been compressed.

Question 5

What is the primary difference between a compressor and a limiter?

Accepted Answer

A limiter is essentially a compressor with a very high, often infinite, ratio.

Answer

A limiter can only be used on the master bus, while a compressor can be used on individual tracks.

Answer

A compressor has attack and release controls, while a limiter does not.

Answer

A compressor reduces the volume of quiet sounds, while a limiter reduces the volume of loud sounds.

Question 6

Which of the following describes the function of upward compression?

Accepted Answer

It increases the volume of signals that fall BELOW a set threshold, leaving loud signals untouched.

Answer

It increases the volume of signals that go ABOVE a set threshold.

Answer

It attenuates the signal as soon as it is detected, with no attack time.

Answer

It blends a dry signal with a signal that has been processed by a downward expander.
