To see what a given input file sounds like after being transcoded to
each of several different output formats, at a couple of different
bitrates in your range of interest, just run a for loop in Bash, no?
Something like (untested):
for i in {m4a,ogg,opus}; do
for j in {64k,96k}; do
ffmpeg -i infile.flac -b:a "$j" outfile_"$j"."$i"
done
done
Tweak this for more detail if desired.
Then listen to the results, and go with whichever combination of bitrate
& codec you find most satisfying?
