Expanders may be used for many purposes, both technically and artistically. These include
background noise reduction and file clean up, the reduction of ambient noise disturbance in
live recordings, presence and dynamic profiling of instruments, and creative control of
ambient reverb etc. Because the Oxford Expander has 20 samples of signal preview, it is
particularly useful for instrument dynamic profiling, as it can act on the signal before gain
control actually occurs, meaning that, for example, you can actually profile the leading edge
of a percussive attack.
2.6 Gate
The Gate controls of the plug-in are presented similarly to the Expander function, except that
there is no Ratio control. Programme gating has become ever more popular in recent years,
since its inclusion in some professional console systems. Originally intended as a technical
tool for tape noise suppression and similar functions, many useful and often fashion changing
artistic effects have been achieved using gates.
