maybe.
the problem is many audio streams do not have presentation time stamps.
(PTS) IE when to present it (absolute time)
Video+audio streams have relative PTSs to ensure lip sync once
presented to the user.
I have 3 different DAB radio sets in my house and they ALL have
different presentation delays so having the cricket on in different
rooms with different radios is a audible delay mess.

the counter.
60 years later, technology has advanced a bit! However, the town where I
live does sound its fire horn every day at noon -- presumably so that
people can set their clocks. Maybe everybody has a mobile phone these days
and can get an accurate time that way....
