It's perfectly normal. Export puts Jack in 'freewheeling' mode
which means that it doesn't sync to the soundcard but starts
a new cycle as soon as the previous one has ended (the sound
card output gets 'silence' for output meanwhile, and input is
discarded). So things will run 'as fast as possible' which
means CPU load will go up to 100%.

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
