JACK-managed thread ("audio thread")

• executes process/xrun/sample_rate callbacks
• must be "real-time safe":
  • nycles = (A * nframes) + B
    where A and B are constant
  • no blocking calls
    • malloc
    • sleep
    • read/write/open/close
    • pthread_cond_wait
    • pthread_mutex_lock

Other Threads
