correct "pin setup" for Surround Pan 5.1

Qbrick wrote on 4/24/2025, 2:14 AM

Hi,

what's the correct setup for Surround Pan 5.1 if you have AC3 5.1? the goal is obtain the same channels audio level on export...

I mean:

1) you have a AC3 5.1 audio

2) you convert on flac 5.1

3) you import on Vegas Pro

Which is correct?

Thanks!

From your images, it looks like that you have 6 separate audio events - 1 each for FL, FR, C, RL, RR and LFE - and each has its own track. That's absolutely fine, but I'd start off with the centre pan point to be left at its default centre position. If you need to adjust the volume of any of the tracks, you can do that with the fader in the track header.

I could well be corrected on this point, but the pan point is best used when the 5.1 surround audio is contained in the one audio event and the pan point is moved to favour the fronts, rears or sides - or combinations thereof.

In Vegas Pro, R click on the surround panner in the track header, click on Sound Panner in the context menu and the sound panner window will open. Have a play around with the pan point and you will see what I mean. Also note that moving the pan point directly up to the C position doesn't alter the volume of the C channel - C volume is only altered (reduced) by moving the pan point down from the centre of the panner away from the C poistion.

down from the centre of the panner away from the C poistion.

When I drag and drop to Vegas Pro a flac file (5.1 --> 6 channels) I obtain 6 distinct treacks on Vegas

Is it possible drag & drop a flac on a one (5.1 type) audio track?

Or: What the correct way to import a 5.1 (lossless) file on Vegas Pro? I want the same audio levels (as the original) on every channels when I'll epxport :)

@Qbrick, please add the images directly to your post instead of on an external website.

@jetdv I've added them.

Not using FLAC thus far, I downloaded a sample 5.1 FLAC file that I found on an audio website and imported it into Vegas Pro 22 ... and it did import as 6 separate tracks just like you got:

BTW, I suspect that the sample track was a 2.0 track converted to 5.1 - not that that should matter for this purpose.

Importing the same FLAC audio track into another NLE resulted in just the one audio track with 6 channels rather than 6 separate tracks.

I've looked through Vegas Pro's preferences (including Internal Prefs) but could not find any obvious setting to change the behaviour with FLAC 5.1 audio, and nor could I find anything relating to this by doing a forum search for FLAC.

Hopefully, someone on the forum may provide have some suggestions based on experience about FLAC 5.1.

I would think that you will get that very result if you don't make changes to the audio levels using any of the pan points in the surround panners or any of the faders in the track headers.

We have the definitive answers (pics from Adobe Audition):

original from source:

PIN on center:

PIN on top:

As you can see (download 3 pics and cycle through them with IrfanView for example):

  • "original" = "PIN on center"
  • "original" <> "PIN on top"

So if I want export with the same audio level ( = without alter the audio wave) I have to choice "PIN on center"

PS

the 3 audio clip are perfectly aligned:

Mmmm ... that's what I wrote before:

 Also note that moving the pan point directly up to the C position doesn't alter the volume of the C channel - C volume is only altered (reduced) by moving the pan point down from the centre of the panner away from the C poistion.

That I would have thought was "definitive".

And also:

I'm not sure that I will be responding to this forum member in the future.

Sorry, I didn't read very well your response. I'm not speaking English very well.

I marked your post as definitive solution.
