Convert True HD 5.1 to WAV

Hello
I want to convert a Dolby True HD 5.1 track as it comes in the Blu ray to WAV so I can use it in Vegas.
At first, I converted it to a single 6 channel wav with eac3to, but I just discovered that the channel distribution when imported to the timeline is wrong.
I read about the problem and tried to use again eac3to to convert it into 6 different ways using .wavs in the command. That way I got the following files:
Stem C
Stem R
Stem LFE
Stem L
Stem LS
Stem RS
When I import them to Vegas I don’t know how to map them or how to keep them loseless. Are that 6 mono files keeping the True HD?
I would like to obtain a single file because I’ve already edited a lot in the timeline and I could keep them if I replace the w64 5.1 file that I’ve using for the edit. I need a 5.1 wav that contains the correct channel distribution and True HD, and that it will be imported to Vegas correctly to the 6 audio tracks when replacing the incorrect w64.
Cheers

Set your project properties to 5.1. Each track should have a visual representation of the speakers, and you can pan the channel by dragging the orange dot (or however it’s represented in later versions) to the right speaker. Render as WAV/W64, and you won’t lose any quality owing to recompression.

There’s no quality loss upon converting to WAV.

What’s incorrect about the w64 file? Use eac3to to produce one. As long as you set up each track properly, there shouldn’t be a problem.

I meant that I did most of the video/audio editing with the first w64 file, that didn’t have correct channel assignment. So i needed to replace it with another wav 5.1 that had the proper channel distribution. So I created another Vegas project, imported the separated 6 mono tracks and panned each to the right speaker (I hope I did that correctly). Then I exported it as w64 5.1 PCM 24Bit/48.000 Hz. Then I went to the edit project and replaced the original wav 5.1, that was directly converted from True HD 5.1 with eac3to, with the new one. I had to pan again the channels into the right speaker and it seems to be working well but I will do a test.

I didn´t have sound in Channels 1 and 2 with Pan Type set to “Constant Power”. I mean, there was no audo sounding while the peaks were there, and that channels were empty in the rendered wav. When i changed the Pan Type to “Film” or to "Add Channels (0db Center), that FR and FL channels have sound. My question is, if i want to keep the pan intact as it is on the Blu Ray, which pan mode is the correct? I just want to keep the 5.1 Ac3 Dolby Digital True HD exactly as it came on the BR. I see that “Pan Type Film” moves the speaker symbol to a middle point between the center and FR speakers in the FR channel panning, between the center and FL speakers in the FL channel, and so it goes…, while the "Add Channels (0db Center) " is just putting the marked rhomboid symbol in each speaker. Do you know which way is the correct to keep the channels intact?

Create a new project. Set the audio to 5.1. Create 6 audio tracks on your timeline. in the surround pan box on each track, move the orange diamond to the speaker that corresponds with the surround channel you want to use that track for. Make sure you then mute all other speakers that are not being used for that track by clicking on each one. When muted the unused speakers will be a lighter grey. Right click on the surround box on each track and set the pan type to “Balance 0db” for the first 5 tracks. on the 6th track, right click on the surround box and set that to “LFE only” . Import your mono wavs and place them on the corresponding track. Now you can export them to wav64 using the “Sony wav64 - 48,000hz 24bit 5.1 PCM” preset. Don’t have “enable multichannel mapping” ticked. then export you file. When you want to import it back into vegas , import the file then drag it onto your timeline to create new tracks ( a blank area below your existing audio tracks). Don’t drag it onto existing tracks as this can mess up the channel mapping. It will create 4 new tracks: Stereo F&R, Mono Centre, Stereo SL&SR and LFE.
