What is DC offset in this context? I've seen this

before, but don't really understand what it means.
Is this the same thing refered to by the ecasound options -ezf and -ezx?
-ezf
Finds the optimal value for DC-adjusting. You can use the result as
a parameter to -ezx effect.
You have to beware of this, as it will only correctly fix a constant DC
offset (I know thats a tautology, but bear with me ;), you can fix
non-constant (which is more common), by using a very low cutoff, low order
highpass filter, as in the LADSPA dc_remove plugin.
