Hi, I have Windows 8.1 in my 1TB HDD, 8GB of RAM, i7 4th gen. and Audacity 2.0.5. I’m trying to synchronize an AC3 audio track with 6 channels (Dolby 5.1).
First, the length of the audio track is 4h . So it takes a HUGE lot to load in Audacity, and running my computer with a HDD doesn’t help much, xD.
Well, all I have to do is add 2 seconds more of silence in the middle of the track, and then it’s synced. AFTER doing that, I select “export…”, selected AC3 using FFMPEG and OK. After start exporting, Audacity asks me to put each track in the channels I want them to be. By default Audacity selected 1 channel for each track. I didn’t move anything cause everything seemed right, and clicked OK.
Took 20 min, lol. Then, I listen to it, and I only hear voices in the left headphone. Seems like if the default selection of the channels were something like ALL the voices tracks to the left speakers, rest of surround and subwoofer, to the right. So here go the questions:
When selecting in which of the 6 channels I wanna hear each track, how can I know if the channel I selected is the subwoofer center, left speaker, right speaker, centre speaker, back left speaker or righ back speaker? Because I was so unlucky that Audacity put all the 3 audio tracks in the left side.
Is there any way I can leave the AC3 track in its original quality? Just add the 2 seconds and save it as it is, without compression. I’m saying this because my exported AC3 audio track is 300MiB and the original unsynced track is 700MiB, and I notice that the quality of my exported AC3 was worse.
