The join filter appears to work - specifying a 6.0 layout does indeed
output what I want, but: the backend video player (AVPro) in the game I'm
playing does not respect/acknowledge 6.0 (seemingly) so that doesn't work.
Also the webplayer for the CDN I'm using also does not work (flv.js). Lucky
me!

Unfortunately due to platform limitations, AAC is the only
mutli-channel audio codec supported in my use case. However, I do not see,
at a glance, where the AAC specification mandates that if there are 6
channels, that channel 4 must be a 128hz LFE channel. AAC also supports the
6.0 channel layout

That's what I thought! However, here are some commands showing this. I set
the lowpass to be 10khz on channel4 just to prevent any confusion (it
should clearly _not_ sound like any kind of real low pass filter). With an
input of "vid.mp4" that has standard stereo, run the following:
ffmpeg -i

A more succinct way of putting it: if I channelsplit (or any other type of
upmixing as far as I'm aware) into 6 channels, channel 4 always has a 128hz
low pass filter applied to it. I do not want this
My particular use case is I play a game that supports multi-channel live
audio streams, but no

Hi I'm probably using ffmpeg in an edge-case way, but I simply want to take
2 channels/stereo, and end up with 6 channels of audio, where I can
apply/modify/filter each channel as I please. And I figured out the ffmpeg
