JACK as an audio API

• providing a new API was never a central goal of JACK
• enforcing a new programming model was

• as an API JACK provides many benefits because of its high-level of abstraction:
  • no hardware configuration
  • no software (driver) configuration
  • no format negotiation (all channels are mono, 32 bit floating point)
  • no main loop (JACK-managed thread handles it)

• on the other hand:
  • requires multi-threaded (lock-free) programming skills
  • involves use of a client/server system
  • "pull" model is harder for some kinds of apps
