The good news is that ffmpeg appears to include the soxr algorithm anyway.

Yep, was looking at that. But would appreciate any additional insight,
since I am not entirely sure how to read that. For instance, if I compare
SoX to FFmpeg, yes, SoX looks way better in this particular case. Question
is - are these meaningful differences?
Also, the test goes from 96kHz back to 44.1kHz, and people very rarely
upload 96kHz.
So, I would mostly be interested in 48->44.1 and 44.1->44.1. Specifically,
does anything change in the latter case?
