Thank you kindly for your fast and very thorough reply. I did indeed place the settings as you have said and yes, I have installed “32 bit FFmpeg for Audacity Only” and it tells me that is already sees it. So all that is fine.
I DID happen in the meantime to stumble upon a nice thorough Blu-ray authoring tutorial on DOOM or some such, and within it’s lengthy instructions it did show in detail how to export from the 6 Mono files using ‘Other Uncompressed Options’ simply choosing either WAV or FLAC format (I wasn’t aware that they supported multi-channel files) NOW, with trying THAT I at least did get it to do something and not just sit there like it did when I tried the ‘Custom FFmpeg’ choice and it DID indeed render a file in each case. One FLAC and one WAV. In both cases I got the nice diagram showing the 6 channels going directly to 6 channels.
BUT… When I then went to try and listen to either file (using VLC because I figure it plays bloody everything) I sat there as the progress bar moved naturally as if the song was playing, but there was only silence…
Sorry to be so long-winded, but here is a simple synopsis:
When trying to use the ‘Custom FFmpeg’, then seeing the 6 channel diagram, when I then hit ‘OKAY’ it just sat there and did nothing. A resulting file showed on my desktop, but it was ‘0’ bytes in size.
When I used either WAV or FLAC as my choice, it DID render one file in each occasion, but I cannot hear anything when trying to place either of them back with VLC. And I checked each file using MediaTab and supposedly in each case it showed an uncompressed 16 bit audio file and bit rates like SOMETHING was there.
And, as far as the command line stuff… Well, I’m sorry to say that that is WAY beyond my ability I’m afraid; a bit too complicated. BTW, SHOULD VLC be able to play the uncompressed 16 bit WAV or FLAC files that Audacity generated? I’m pretty sure it plays back 5.1 audio files because the MKV snippet that I extracted from the movie that contains the original DTS file plays just fine with along the video (the snippet is a song from the closing credits of a movie that is about 3 1/2 minutes in length.
Here were the steps I took:
I took the 4.4 Gig movie file (MKV containing MPEG4 video & DTS audio) and I used MKV Extract to strip out the full DTS soundtrack.
I then loaded the DTS file into Audacity and edited out everything except the 3 1/2 minute song. All 6 Mono tracks were shown and played back just fine in Audacity (I know it wasn’t playing back all 6 together, but everything seemed to track and be working just fine.
Here is where I’m stumped. I cannot seem to export the damn thin properly into a playable format that I can hear (the WAV & FLAC renderings) And, I cannot render anything at all using the ‘Custom FFmpeg’ option.
So, I am sitting here with this nice 3 1/2 minute song sitting in Audacity in 6 lovely Mono tracks, and here I am…
I hope you don’t mind my being so detailed, but I wanted you to understand where I am in this. BTW, your search function is so beyond me, there is NO bloody way for me to find where that link was. But, later on before I got your reply, I DID see another link about the same thing and this one did take me to the manual where it explained in detail how to use the ‘Custom FFmpeg’ option. But, when I hit ‘OKAY’, nada…
Now, I DO have the MKV snippet that has both video and audio that I painstakingly extracted from the original 4.4 Gig file using Avidemux (that took a while!) And I can play the MKV snippet with VLC or on my Blu-ray player (if I wanna hear it in 5.1) just fine. But the edit isn’t that great with Avidemux and it has like 10 seconds before the song starts and about 10 seconds after the song ends, not to mention the accompanying video which I don’t need. So, that is why I used Audacity, so I could get the edit exactly right. But, now that I have, I cannot for the life of me export it in any usable way. (BTW, the song is by RUSH’s Alex Lifeson who does this GREAT little song at the end of the film ‘DOUBLE’, so I promise you it is worth it! )
Thank you again for all your help!
