How do I turn ordinary speech into something inaudible, in Adobe Audition? So it sounds a bit like mumble
I think that comprehensible speech consists of vowels and consonants put in some order. Killing one of the two will make something incomprehensible.
I would try to kill consonants to be more exact, ...

How can I merge two sound clips *without* crossfade to achieve a seamless transition?
Not unless you join at a zero crossing; i.e.where the wave crosses the centre line & has 'no volume' [but then, all your edits should be at zero-crossing anyway].
Even Audacity has cross-fade. It'...

Is it legitimate to use a low pass filter on short segments of audio around stitch between two amplitude signals to remove noise?
The answer is to be found in understanding what a crossfade is. A crossfade can be either "Constant Level" or "Constant Power". One is linear, one is logarithmic in shape.
You need to build a table ...
