Compression and Dynamics Processing

Start with compression

The Compression mind map introduces compression as a way to reduce the dynamic range between the loudest and quietest parts of an audio signal. It describes boosting quieter signals and attenuating louder ones. Another mind map with the same title also introduces this process, so you can look at both explanations as you study.

Compression and EQ offers another starting point. Its compression section describes controlling dynamic levels and removing peaks. Controlling Dynamics introduces changes in volume and the measurement of sound level in decibels.

Move from maps to flashcards

After looking at a map, use Music Tech: Compression to check the terms you have encountered. Its questions cover dynamic range, threshold, gain reduction and compression ratio, along with threshold and ratio diagrams. Return to the maps when you want to look over an explanation again.

RTEC SEM 2 asks about gain riding, why a compressor is used and what its threshold does. The Music flashcards include questions about noise gating and references to videos on automation and compression.

Explore gates and signal processing

Music Tech Assessment describes a noise gate that mutes a signal when its input falls below a threshold. The noise-gate mind map also discusses letting a signal through or stopping it, including use with a microphone affected by unwanted background noise.

Signal Processing is the quiz on this page. Its questions include compressor or gate attack settings and cutting a frequency with a de-esser. The attack question is described as based on personal opinion, so consider that context when using it.

Use the collection together

These resources form the Compression and Dynamics Processing section of Music Technology and Production in Music. The maps give you explanations to explore, while the flashcards and quiz offer questions to work through. Choose a term from the quiz, then return to a relevant map or flashcard deck to study it further.
