You are right, eac3to is great. But I skipped in my file and compared the audio and I found out that I mapped the channels wrong. The example I picked has a centred voice in the original DTS, my audacity flac has it on the right ear, the output from eac3to on the left. (I'm using stereo headphones)
Code:
command line: eac3to "input.dts" "output.flac" -25.000 -slowdown -167ms -2,0,1,4,5,3
audacity mapping see previous post
(unimportant fun fact: the output from eac3to is with 660MB twice the size of audacity output, both flac)
Do you recognize where I failed at mapping?
And, as eac3to doesn't support opus output, should I simply go with AAC after my tests are finished?
