Digital audio represents data as bit patterns. As such they are easily transmitted and stored either for archiving purposes (on hard disk), or for temporary purposes ("buffering" audio data). Buffering data has the undesired effect of delaying audio, and should hence be avoided where ever possible. In this article we present a design tactic for digital audio systems that avoids buffering and that relies on the predictable nature of underlying hardware to deliver data just-in-time. We show how to use this tactic, how to compute minimum buffer sizes required, and how to scale the design to larger systems.
