Dynamics Processors-Advanced Controls Flashcards
What does attack do?
Controls how quickly the processor responds to a signal once it crosses the threshold
Fast attack
The compressor engages almost immediately, reducing the signal’s volume quickly, useful for controlling sharp transient like drum hits
Slow attack
The compressor takes longer to respond, allowing the initial part of the transient to pass through before reducing the signal’s level (Suitable for strings)
What does release do?
Controls how quickly the processor stops reducing the signal’s volume after the input signal falls back below the threshold
Fast release
The processor stops compressing quickly after the signal dips below the threshold, which can give a more punchy or dynamic feel but may sound unnatural if set too fast
Slow release
The processor gradually stops compressing, creating a smoother, more controlled sound but potentially reducing some of the dynamics if too slow
What does knee do?
How the compression transitions as the signal approaches and exceeds the threshold
Hard knee
Compression starts immediately and sharply when the signal exceeds the threshold, applying the full ratio instantly
Results in more aggressive and noticeable compression, which is ideal for when you want to clamp down on loud signals quickly
Soft knee
Compression starts more gradually as the signal approaches the threshold, slowly increasing the amount of gain reduction
Creates a smoother, more naturally-sounding compression, making it useful for more transparent control over dynamics
What does make-up gain do?
Compensates for the overall volume reduction caused by compression to restored the signal to its original or desired volume level
Without make-up gain
The compressed signal might sound too quiet compared to the uncompressed signal
With make-up gain
You can bring the overall level back up after compression, maintaining consistent loudness while keeping the dynamic range controlled
What does side-chain do?
An external signal used to control the compressor or other dynamics effect, instead of the signal being processed itself
Without side-chain compression
The compressor reacts to the loudness of the signal it’s processing
With side-chain compression
The compressor reacts to an external signal
For example, a kick drum can trigger the compressor to lower the volume of a bass track every time the kick hits
This technique is called ducking, popular in electronic music to make space for the kick drum by reducing the bass’s level temporarily
