combine multi source audio files to export interleaved audio

One of the main features listed in the 17.3.1 release notes is the ability to 'combine multi source audio files to export interleaved audio'.

I was hoping this meant we can finally create an empty 5.1 audio track and populate it with six separate mono audio files, but I haven't been able to accomplish this.

Has anyone figured this out yet?

I just tried this and got it working with the following method. No idea if this involved the 17.3.1 change, as I'd never tried it in earlier versions:

1. Create a Timeline containing 6 x mono tracks


2. Go to the Fairlight page

3. Fairlight menu -> Link Group

4. Select the six tracks, then Link as: 5.1 (or 5.1 Film)


5. Deliver page, Single clip mode, Audio, Output Track 1: Timeline Track, choose Track 1, and see it shows "5.1" next to it:


Render that and drag the resulting file back into Resolve. It has 6 channels and is recognised as 5.1:


And in MediaInfo:

Code: Select all

Nice!

My workaround is creating a 5.1 track, then 'Convert to Linked Group' and drag the mono clips into it, and then it behaves pretty much like a normal 5.1 track.

It would have been nice and a lot less cluttered if you could just drag'em into a native 5.1 track though.

Ahh OK, I misunderstood and thought you wanted to actually export a file, like the change log was referring to.

Yeah if you just want a 5.1 track in Resolve, Convert To Linked Group on a 5.1 track - or the Link Group method I used here - is the way to do it.

Look a export in the fairlight timeline right click.
See the clips or range on the timeline first

Oh yeah, cool. So if you choose "Interleaved - Single File":


You can export this:

Thanks Peter, this is a great feature!

Nonetheless I would still like the option to create a multi channel master clip from a selection of mono audio files, and 'populate' a multi channel track with mono files of my own choosing.

This would frequently save me some time and help make projects less cluttered and less error prone.
