I have to encode a 5.1 mix for a film into LT RT. I have never done that before, and it does not seem to work.
I have the 5.1 mix as 6 separate files. I have created a new session and then import all the files to 6 different tracks. I created a 5.0 output and deleted the lfe. So the remaining 5 tracks I route to the correct output on the 5.0. Then I insert the Matrix Encoder in the 5.0. I get a good sounding stereo file.
Now I want to reverse the process. I create a session with an LRCS output. I import the stereo encoded file and put the decoder in the LRCS output. What I hear now is a mono file. What am I doing wrong?
