Also…the phrase is lowest common denominator; and it applies for both
here. If the phones don’t do 44 but do 22khz; then 22khz the idiom applies
here too. It’s mostly a way of stating they find some kind of common
ground to work on; it’s not always literally the absolute lowest.
If one side offers 44kHz, 22kHz and 8kHz, and the other side offers 22kHz and
8kHz, then the lowest common denominator is 8kHz.
The highest common denominator is 22kHz.
To avoid mathematical / philosophical / linguistic arguments, I suggest people
say somethng like “the highest common capability” when talking about two sides
negotiating what quality to use.
Basically, the two sides offer each other the list of rates they support, and
the agrrement is the highest which is on both lists.
