Demux and remux AC3 (channel mapping)

OtonVM · 14th April 2009, 10:36

I had to resample an AC3 5.1 audio track (for PAL -> NTSC conversion) so I used tmpgenc xpress 4 to select each channel and export it into wav.

The result are 6 mono tracks: FR, FL, FC, LFE, BR, BL.

I opened them in Audition and ran a resample script in batch which exported again 6 tracks. I kept the names consistent so I would not confuse which channel is which.

Than I imported them into WAV to AC3 encoder with the MUX Wizard so I could map each channel properly.

The resulting AC3 sounds wrong, panned to the right, dialogues are muffled.

I guess I mapped the channels incorrectly. Am I missing something?
