Doesn’t that plugin already output the correct mix including generating the LFE out of the bass part contained in the rear channels? Actually it should be possible to create a FLAC file or other format “on the fly” directly in Foobar as well.
Well, it kind of does. It does output all 6 channels, including the LFE channel, but for my purposes I wanted more than just a single file of all combined channels.
The CD-ROM disc contains PLAYLIST.TXT, DTS.EXE, and a folder called DTS. Inside the DTS folder are 4 files. Each file contains roughly a 20 minute section of audio from the movie. All 6 channels for that 20 minute section of the film are contained in each single file. For example, the file “S1003T6.R1” contains the first 20 minutes of 6-channel audio in the movie, starting from the DTS logo at the start of the movie till about the time the helicopter lands on the island.
The problem is that Foobar couldn’t open those 4 files in their native format on the CD-ROM. The files on the disc didn’t have a recognizable file extension. So, I copied the disc files to my computer and added the .AUD extension to each file. I was then able to open the files and play them back in Foobar. I still wanted to take a look at the individual waveforms themselves, so I used Foobar to convert the .AUD files to .WAV files. Each .WAV file contains all 6 discrete channels, although some of the individual tracks are paired as a L/R stereo track.
Opening each .WAV file in an audio editing app allowed me to separate those paired stereo tracks back into individual mono tracks that I could then pan left or right depending on what the track was. And I could isolate each individual track and listen to them separately, just for fun.
