Abstract:
Audio Signal Processing systems have come a long way since the early days of a main() loop with calls to input/output functions, communication functions, and signal processing functions. These advances have come about due to the need for the embedded audio DSP to balance performing more complex tasks and reducing development time and effort. This tutorial session will explore a few advances in the area of audio signal processing systems and focus on some key concerns with each of them. In particular, the topics that will be discussed include simultaneous audio inputs and multi-zone outputs, control architecture, device interfaces, memory management, and use of real-time operating systems (RTOS). Additionally, some systems-level issues with audio-video mixed products will be described.
