Cubase14 -Latency: buffer size 32 - 4096 no difference at recording?

Cubase

Hi guys,

I thought I understood latency but now I know I don’t.
Recently I did some updates on PC (Drivers, BIOS, etc.).
After that I ran into a Recording error: Audio drop out detected.

I used to record with 64 buffer size, and just thought okay, let’s increase buffer one step up, check latency for record shift and I’m good.
Then I checked my HW latency via a loop test:
TRACK → Mixer Out → (Cable) → Mixer In → NEW Track record.

At this test I found that nothing changes, between 32 - 4096 buffer size.
I usually record with no plugins, vst’s etc. enabled.
But I expected to see a difference between the two test tracks I recorded due to buffer change.

My HW is a RME Digiface (PCI-E) with a Yamaha 01v96v2.

Can anybody explain me why there is no change, when I change the buffer size?

Here a screenshot from the test setup:

There is no change because Cubase is compensating for the reported latency and changing buffer changes the amount being reported correctly.
The loopback test (and record offset) is testing and fixing unreported latency in your system which usually does not change with buffer setting but will probably change with sample rate.

Thanks, understood.

The existing (not changing) offset is now just my Mixer.
Thats good to know.

Was this always like that in Cubase?
I can’t remember this behavior almost 20 years ago, I used Cubase 5 at the time.
I’m just recently back in music :slight_smile:

Cheers!
