Way to split AAC file without reencoding?

I have a 90 minute AAC file I'd like to split without reencoding and was wondering if it was possible in foobar2000. The only other way to do it I've been able to find is BeSplit, which is incredibly old and requires WinAmp for some reason. I'd rather avoid that because in foobar the chapters show up (it's actually a video from a concert) and I'd rather not have to manually find the start and end points of each song.

mp3DirectCut, despite its name it can also cut AAC files.

If I understand you correctly, it is contained in MP4/M4A container and has chapters which fb2k can show as sub-tracks,  and you want to split it according to chapters?
Then try https://github.com/nu774/m4acut/releases

It's a simple CLI tool, so you have to use it from command prompt.
However, it can automatically split input according to chapter points or cuesheet, preserving original tags, taking care of frame boundaries/padding, enabling perfect gapless playback.
You can manually split by specifying start/end point if you want.
All other tools I know don't support gapless playback of resulting files (that's why I wrote it).

First:

Then, find the readme on the page here and experiment:

BTW, thanks nu774 for a boss tool.  squirtmph, if your needs are less exacting you might take a look at LosslessCut:
