Transcript of The Ableton Live Compressor

The purpose of this presentation is to demonstrate how to use the compressor included with Ableton Live 9 topics to be included are
Reflection
The Ableton live 9 compressor has the following features
Setting Values
On the left of the compressor are three controls. They are from top to bottom
Views Available in the Compressor
Collapsed View
This view is designed to show only the essential controls and includes

The threshold level on the left

A visual indication in the form of a inverted level meter which shows the amount of gain reduction

An output gain control - which controls the level of the signal after compression inthe middle

At the bottom of the display is a knee control

Visuals viewpoints of the effect of the compressor
By Mike Wilkinson from Leicester in the United Kingdom
Other controls and modes
We start with the different views because this has an impact on how the threshold value is set
There are three views available
Collapsed View
Transfer Curve
Activity Display
Transfer Curve
This view shows a graph of input level along the horizontal axis and output level along the vertical axis. It also contains

A control for threshold level on the left
An output gain control - which controls the level of the signal after compression the right
Controls for the knee and lookahead time
and linear/logarithmic release along the bottom

If the yellow circle on the orange line is moved (with the mouse or the cursor keys) left and right it changes the threshold and up and down changes the ratio
Activity View
This view has two mode selected at the top marked GR (Gain Reduction) and Output

The threshold value and output level are modifiable fields at the top of the display

At the bottom are Knee value, and Lookahead time and linear/logarthmic release time
This view shows the input level in grey and the amount of gain reduction in light orange

The horizontal orange line is the threshold level and can be used to modify the level

The images on the left show the display for the same drum loop at two ends of the threshold scale
Activity View showing Gain Reduction
Threshold value
-62.2db
Threshold value
-3.43db
This view shows the input level in grey and the ouput level in a darker grey

The horizontal orange line is the threshold level and can be used to modify the level

The images on the left show the display for the same drum loop at two ends of the threshold scale
Activity View showing Output Level
Threshold value
-62.2db
Threshold value
-3.43db
Collapsed View
The images on the left show the display at two threshold levels at different ends of the threshold scale on the same drum loop
Threshold value
-3.43db
Threshold value
-62.2db
The images on the left show the display at two threshold levels at different ends of the threshold scale on the same drum loop
Transfer Curve View
Threshold value
-62.2db
Threshold value
-3.43db
Setting Values
Below these controls is button marked auto which enables a release time to be automatically calculated based on the input signal level
To the right of the compressor are
reflection
Ratio which sets the ratio of compression between the input and output level
Attack which set the time to reach maximium compression when the signal has exceeded the threshold level set
Release which sets the time for compression to stop after the signal has decreased below the threshold level
the markup button which enable automatic adjustment of the output level based on the threshold level and the ratio
The mode button which switch between peak mode, RMS mode and the expander mode in which the compresssor operates as upwards compressor
Finally there is a wet/dry control to allow parallel compression values to be set
Multiple views of the compressor's effect on the input audio signal's level
Multiple modes of operation includes 2 forms of downward compression and 1 upwards
Selection of automatic operation of release time and output level selection
This concludes the presentation thanks for watching
