Sorry if this has been discussed and answered before, but I have a question about finding the center channel to export in a 5.1 set-up.
I am able to isolate the vocal/center track from a video to use for video editing, and when I try to export it, I’m not able to identify the correct channel. I choose export and then it takes me to the channel screen, with only one displayed. I expand to 6 channels and I have matched the file with each channel separately and exported all the different files. On some channels, it plays in the left, some in the right, and some none at all! On the ones where it does play in an incorrect channel, it does also play in the center, but none in the center only. Any advice?
On second thought, I’ve only previewed the output file through the video editing program in which I’m using it (avs4you), and not as its own file. That may have something to do with it, but feedback is still appreciated! Thanks again!
and exported all the different files. On some channels, it plays in the left, some in the right, and some none at all!
You exported 6 separate files?
You’re just trying to get a mono file that plays from only the center speaker? With the other channels silent?
What format did you export to? WAV?, AC3?
Did you export in mono?, stereo?, multi-channel?
I think a mono Dolby Digital file will play out of the center-channel only (unless you use a Pro Logic option to “spread-out” the sound). …Or maybe you have to make a 5.1 (or 5.0) file with all channels silent, except the center channel.
In Dolby Pro Logic, a stereo file with identical left & right channels should be steered to the front-center, or a mono file should be steered to front-center.
I’ve never made a 5.1 channel file with Audacity… I’ve made 5.1 channel DVD files by making 6 mono files and then making an AC3 (Dolby Digital) file with [u]wavtoac3encoder[/u]. (Then, I used my DVD authoring application to combine my audio & video and make a DVD.)
I deleted all the channels except the one I needed and then exported that in each channel to test it out. I did it in mono as a FLAC.
What I’m trying to do is to add the vocal/center channel to an already-existing audio mix in the video. Like I said, though, it may be due to limitations in avs4you; if I can’t get any solutions here, I’ll contact them.
You mean you want to make all six channels have the same content (your one vocal-removed track)
If that is what you want, then in the Advanced Mixing Options window you should move the slider to six channels, click on the track box on the left of the window, then click all five other channels, so that each channel has a line connected to the track box.
Audacity doesn’t do multi-channel playback so what it sounds like depends on the player app and the sound card.
No, just the center channel. I’ll try with the video program and see what I can figure out.
If you have the center channel audio copied into a mono FLAC you should be OK.
That’s assuming AVS4YOU can accept FLAC as input. I’ve never used AVS4YOU. You may have to make sure AVS4YOU “knows” it’s a mono file. You may have to make a stereo file with the same signal in both channels, but I wouldn’t expect that.
If you play a mono file on a regular 2-channel stereo system the sound should come out of both speakers.
If you play a mono file on a surround system, it may depend on the settings… But the sound shouldn’t come only from the rear, or only from the right or left, or anything weird like that.
