One of the Audacity developers has been looking into this.
It appears that there has been a problem with the AAC encoder for a long time, but it has been mostly hidden by another bug. That other bug has now been fixed, exposing this bug. This is now logged on the Audacity bug tracker.

Re: Fixing "Robot" Voice
a series of lectures I need to watch for class. (This will amount to several dozen hours of audio with this problem If your tutor expects you to listen to many hours of such badly recorded material, your entire class should put in a joint complaint to the school / college.

Re: Align similar tracks exactly
I don't understand what you are asking. If both projects are simply different edits if the same file, then you already know that they are the same except for an offset, so why do you need to test?

Re: Problem with effects
For Linux Mint users, or Ubuntu users with Flatpak enabled, there is a working Flatpak for Audacity-2.4.1 which provides all effects correctly. Last time I looked the Flatpak builds had problems with external libraries and plug-ins, such as LAME, FFmpeg, and third party plug-ins. Have you checked t...

Re: mono recording for a multitrack
The ability to map physical inputs to recording channels is still a "wish list feature" (Audacity does not yet have this feature. A workaround is to record 2 channels stereo, then split the stereo track to mono , then delete the unused track (click the [ X ] in the top left corner of the t...

Re: Audacity theme in Ardour (-ish) style
The ones above have all names starting with "Tn" (TnStartOn, TnCalibrate, TnAutomateSelection...) They relate to an experimental feature that was added and abandoned many years ago. There's not many references to it, but here's one: https://wiki.audacityteam.org/wiki/Experimental_Features...
