I've tried ffmpeg, nero, eac3to, tsmuxer, libav, qaac and megui. I have a 6 channel aac from a movie. I just want to demux it to 6 mono wavs. I keep getting the error the Nero Decoder 2 instance failed, no matter what I do, trying other versions, etc.
In 2020 is there still no easy way to do this? Please advise. I'm on Win 10.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

Have not verified this yet, but why don't you try doing it in 2 steps?:
multichannel AAC -> multichannel WAV, and then
multichannel WAV -> individual mono WAV files
There seems to be a number of tools that should do that.

Or just put the aac file and batch file in a folder the CLI can write to.
Try this minor modification in a batch file:
Code:ffmpeg -i %1 -filter_complex "channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL][BR]" -map "[FL]" "%~dpn1.front_left.wav" -map "[FR]" "%~dpn1.front_right.wav" -map "[FC]" "%~dpn1.front_center.wav" -map "[LFE]" "%~dpn1.lfe.wav" -map "[BL]" "%~dpn1.back_left.wav" -map "[BR]" "%~dpn1.back_right.wav"
