Audio processing and functions
Background
Audio processing in Cubase LE can be called “non-de-
structive”, in the sense that you can always undo your last 
operation using the Undo command on the Edit menu. 
This is possible because processing affects audio clips 
rather than the actual audio files, and because audio clips 
can refer to more than one audio file. This is how it works:
1.If you process an event or a selection range, a new au-
dio file is created in the Edits folder, within your project...

Common settings and features
If there are any settings for the selected Audio processing 
function, these will appear when you select the function

hidden when the dialog appears. To reveal these, click the 
“More...” button.

threshold level and replaces them with silence. The dialog 
contains the following settings:
Threshold

Levels below this value will close the gate.

The time it takes for the gate to open fully after the audio 
level has exceeded the threshold level.

Remove DC Offset
This function will remove any DC offset in the audio selec-
tion. A DC offset is when there is too large a DC (direct 
current) component in the signal, sometimes visible as the 
signal not being visually centered around the “zero level 
axis”. DC offsets do not affect what you actually hear, but 
they affect zero crossing detection and certain process-
ing, and it is recommended that you remove them.
There are no parameters for this function.
