Are we assured that a typical digital high pass filter, say of the type found in the
EQ of Protools 8 and later, removes DC offset?

There's a lengthy back story here which for brevity sake I'll not get into, but it
seems that a digital HPF is not removing DC offset -- at least in PT.

I'm in the process of setting up some tests to prove it one way or the
other for sure, but am swamped at the moment.

Curious if any who are well-versed in DSP might say one of the following:

- that's true, a typical digital HPF will not remove DC offset and here's why....

- only a poorly designed digital HPF fails to remove DC offset.

- you're out of your mind, of course by definition ANY digital HPF removes DC
offsets.

- (something else entirely.)


Curious folks want to know.....

Thanks in advance,
