Just checking if anyone knows of a way to remap the channels of an AC3 file without encoding? Is it possible to do this losslessly? Or do I need to convert to wav, remap and then encode as DTS HD or 640 kbps AC3 etc? Thanks

You could try this:
https://ffmpeg.org/ffmpeg-filters.html#channelmap If you use it with the '-c copy' flag then it shouldn't re-encode the audio. I'm not sure if this will affect the dialnorm value or not though. Thanks given by: alleycat
