Graphs showing the eect of applying ratio
Item Description
1 Input level The ‘x-axis’ of the graph.
2 Output level The ‘y-axis’ of the graph.
3 This portion of the graph is pre-threshold and is unaected by compression, that is, with a gradient of 1:1.
4 This portion of the graph is post-threshold and shows the eects of compression. The gradient is the same as the compression ratio.
5 Threshold The point where the gradient changes and where compression starts to be applied.
6 Graph with no ratio applied, that is, 1:1 gradient. (What you put into the compressor, you get out.)

Threshold
The following diagram shows the eect on the compressor graph of adjusting threshold.
Item Description
1 Threshold: The point where the gradient changes and where compression starts to be applied.
2 A threshold reduction will move the threshold point left, as shown in the example above (green line). Less signal is passed 1:1.
3 A threshold increase will move the threshold point right, as shown in the example above (yellow line). More signal is passed 1:1.
Compressor graph
This section uses examples to illustrate the eect on the compressor graph of
adjusting the compressor’s parameters.
Ratio
The following diagram shows a signal on the compressor graph with ratio
applied; it shows the point of threshold and how ratio aects the gradient of
the signal following this. The graph on the right shows an uncompressed signal,
that is, with no ratio applied.
