a JACK or ALSA "period" is what almost everything on windows and MacOS calls a "buffer".

they do not have a term for what ALSA calls "a buffer" (the entire memory space available for audio i/o, typically mmapped into the using process' address space)

just about all modern audio interfaces use a double-buffer design. while the application writes/reads to one buffer, the hardware reads/writes from the other.

I'm getting a little confused when comparing our (Jack) buffer sizes with those
discussed on Windows, Mac and general music groups.

These latter never mention periods at all, and it's always frames per buffer,
so when trying to make comparisons should I take buffers as 1:1 or should I be
comparing their buffers to our periods?

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
