Questions and Answers

What is a common consequence of a high dynamic range in an audio track?

The track will have a consistent volume level throughout.
The loud parts of the track will be distorted.
The quiet parts of the track may be too quiet, requiring volume adjustments. (correct)
The track will have a low overall volume.

In Audacity, where can you find the compressor effect?

View -> Volume and Compression -> Compressor
File -> Import -> Compressor
Edit -> Volume -> Compressor
Effect -> Volume and Compression -> Compressor (correct)

What does a compressor do to the dynamic range of an audio track?

It has no impact on the dynamic range; it only adjusts the overall volume.
It increases the dynamic range, making quieter parts quieter and louder parts louder.
It completely removes the dynamic range, making audio at a constant level.
It reduces the dynamic range, making the difference between quiet and loud parts less significant. (correct)

Dynamic Range

The difference between the loudest and quietest parts of an audio track.

Compressor

An audio effect that reduces the dynamic range of a sound by making loud parts quieter and quiet parts louder.

Threshold

The level at which the compressor starts to reduce the signal's volume.

Ratio

A ratio determines how much the volume of a sound is reduced after it crosses the threshold.

Limiter

An audio effect that prevents audio signals from exceeding a specific threshold.

Study Notes

Dynamic Range Control in Audacity

High dynamic range audio can cause listener discomfort due to large volume fluctuations.
Audacity offers tools to reduce dynamic range and increase audio loudness.
Volume and Compression -> Compressor effect reduces dynamic range.
Compressor reduces sounds above a set threshold by a specified ratio.
This reduction requires adding "make-up gain" or normalisation.
"Knee width" and "smoothing" parameters minimise distortion.
Use factory presets for initial adjustment.
Master effect or real-time mode for visualizing adjustments.

Compressor vs. Limiter

Compressor vs. Limiter: Both reduce loudness, but the limiter is stricter.
A compressor may allow sounds to temporarily exceed the threshold, while a limiter prevents any sound exceeding the threshold.
A compressor uses a low ratio, while a limiter is harsher in its approach.
Both effects benefit from factory presets to get started.
Master effect mode allows for real-time monitoring.
Use limiter to avoid clipping.
