Cubase DC Offset (or any other process) on split audio - Weird behaviour?

Cubase

Hi all,

Currently using both v8.5 32 bit and v11 64bit, bit I assume issue/behavior happens in both?

In v8.5, this is what happens, say I have one vocal wav (for example) that I have split up into multiple parts and I then re-use said parts multiple times all over my project. E.g. a chorus part, and ad-lib, a single sung phrase etc.

If I apply “Remove DC Offset” on one of the said parts, and click on “Continue” I would expect every single split part/copies of the part to have 0 DC offset, in fact I would have expected Remove DC Offset to be applied globably to the whole vocal and thefore all vocal parts?

But this never seems to happen, it’s very inconsistent, usually it only applies to the part i selected and maybe a few other copies of the part. I can’t work out why? What am I doing wrong?

Also is there way of applying DC offset to all parts in the pool? The way I see it, you would always want to remove DC offset right? In my case I always get a lot more headroom.

Hi,

First of all, it depends, if all the Audio Events point to the very same Audio Clip (Audio File). You can check this in the Info Line or in Pool.

Second, the Direct Offline Process (DC Offset in your case) is applied to the Audio Clip as the whole. So if the DC Offset changes during the recording, it might not fit for every single Audio Event. Audio Event is a “window/frame” of the whole file, in fact.

Thanks @Martin.Jirsak , much appreciated.
With what you said in mind, is there a workaround for this?
I’ve been playing around with processing in the pool, which seems to be a better way to approach this as you can see the instances used.

Hi,

You would need to Bounce Selection to get a new file for every single Audio Event. Then you can use the DC Offset individually.

Ah I may have come across a strange (known) bug?
I’ve just started using the pool to do processing (e.g. DC offset remove) and also tidy up the offline history of my parts.
When I use the project window, and click on an audio part, then menu->statistics, it still shows some DC offset.
But when I do statistics for the same part in the pool, it shows 0 DC offset (i.e. the process did in fact seem to work!). I also notice running statistics in the pool takes longer, is it perhaps more thorough?

Hi,

I’m the Pool you don’t edit the Audio Event, you whit the Audio Clip.

In the Project window you are most probably working with the Audio Events, not Audio Parts (if you apply the Direct Offline Process).

I know it’s semantics, but there are no “Parts” in the pool. Only the files (aka the Audio Events).
Just make sure you’re comparing apples to apples.

Hi,

There are no Audio Events. There are Audio Clips. Audio Event is a “window/frame” of the Audio Clip, which you can see (and handle) in the Project window. :wink:

@Martin.Jirsak I stand corrected.
In Cubase nomenclature, I was under the impression that an Audio Event and Audio Clip is the same thing.
Where can an Audio Event differ from an Audio Clip?

Hi,

The Audio Event is just a part of the Audio Clip. You can set Fade In/Out and Gain of the Audio Event in the Info Line. These are not applied to the Audio Clip.

Thanks Martin!

I could also answer this myself by going to the manual… :man_facepalming:
