"Hello, the"?

On my JB940, 46.4 ms.  In divide mode it uses "f" for the duration of an SP
stereo frame, and on LP2 or LP4 recordings each click of the knob jumps 2 or
4 "f"s respectively, each being one real frame.

I don't remember what it does for SP mono: I know that my other Sony decks,
when you try to divide SP mono tracks, offer eighty-six notches per second,
but every other one is fake and will just round to one side or the other if
you confirm division there.  So you really get actual frames of about 23.2ms
of SP mono.

The smallest division is 424 bytes: 11.6ms of both channels of SP stereo,
23.2 of SP mono or of both channels of LP2, or 46.4 of joint stereo LP4
information.  You can't separate the left channel and the right channel of
an SP stereo frame into different tracks from one another.

23.2ms.
