I recently bought the blu ray of "The Eye of the Needle" from Twilight Time. It has a very good isolated score in stereo. Except the Prelude and Finale are edited versions. Composed by the great Miklos Rozsa. These are the original tracks. The Varese release was a re-recording.

The isolated score is in DTS-MA 3.0 channel sound. 24 bit/48. I have already ripped the audio and separated the tracks but when I did this the center channel was lost. Does anyone know how I can keep the center channel?
I have adobe Audion and Audacity. Adobe Audition senses there are 3 channels but playback is mono.

I have no idea what to do. I hope someone here knows. Because this stuff drives me crazy.

Thanks for anyone who can help

Their CAT BALLOU blu was also 3 channel. The Center was the main channel, and L/R were almost unnecessary. Anyway, I use different programs because sometimes you get a glitch (which I did with two programs in this case). Assuming you are actually ripping - not recording the music as it's played - I've used HdBrStreamExtractor, DvdFab HD, and DVD Audio Extractor (the last unfortunately always cuts Blu-ray audio by chapter so cues need to be rejoined - DVD audio can be ripped as one long track).
If you simply google, you'll find lots of discussions on tech sites offering help, like this one:

I used those programs to rip the isolated score as one big file with silences in between. I play that large file in foobar and it says 3 Channel. The problem is when I edit the long track to take out just the music then it becomes 2 channel. The center is gone. Can't figure out why.

Yeah, I had that problem too, although it's essentially the same procedure as separating 6 channels from 5.1. You can use Foobar to do this. When you use the "convert" window, you need click on "Processing" and move "Matrix Mixer" from "Available DSP" to "Active DSP" window. If you dont have that plugin, download and add it to your "Components" folder. You can get it here:
http://skipyrich.com/wiki/Foobar2000:Matrix_Mixer
It's been zipped as a "7z" folder instead of just zip or rar, so you need 7zip(free) or windowsrar to unzip it.
After it's loaded you should see it listed in Foobar's Preferences: Components.

Add your audio in Foobar, right-click to get the Converter window, click on Processing, move "Matrix Mixer" from Available DSP to Active DSP. In the Active DSP window, click on "Matrix Mixer" which will activate the "Configure" button above it. Click that, and you'll get a Matrix display. It should have a bunch of 1's going diagonally down. If you have 3 channel audio, then you only need to work with the first 3 correlations in the matrix - FL, FR, FC. Replacing a 1 with 0 (zero) will omit that channel from being outputted when you "convert." You can get each channel outputted separately, or output 2 channels together as stereo. Obviously to get 3 separate channels, you'll have to replace 1's/0's three times. Note there's a "Normalize" option in the Matrix window margin. Un-tick that to keep the audio original.

Another option is try to load the original in Audacity. That might display all 3 channels, and then you could easily select/deselect whichever. I used Audacity to load my 3 separated mono channels, edited each, and mixed down to stereo.
Or you could upload the audio file (or mail me the disc) and I'll attempt to do it. wink
