That was quite in depth!

Yes,  I liked how they did the latency tests.

They went all in on that one.
Funny enough I recently did my own latency test with my audio interface. Similar, but different.

Was that a clap test?

Something similar, but only with audio.
And then aligning the 2 sources in my DAW to see where the 2nd waveform started.

So they have a built in mechanism for adding/removing delay?

In fact, the DAWS do, so incoming audio is delayed by xxx ms to match the latency the software is introducing.
But this was different.
My audio interface allows for sending audio out and then I returned it after sending it though an FX box (analogue, so no latency) and recorded both incoming and returned audio to see the internal latency.
This is a digital interface, so everything is processed digitally and then converted back to analog. Which apparently takes 1ms.

1ms seems pretty good though.

It's perfect.
Not noticeable

The only problem could be that the 2 could get out of phase, so they cancel eachother out (in some frequencies).
But I never record dry signal coming through this send FX loop, so I'm good.

But once its setup why would it change?

The DAW is fine, but this is my interface.
It can't do this compensation, so it's just something to know and work around.
It will screw you up once and then you know what to do
Very common in the mixer business btw.

You see more and more FX pedals with a true dry bypass exactly for this reason. So you don't get any latency (and don't alter the sound either)
