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%. Ciao, -- FA 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.
