META Advanced Audio Framework (AAF)

The META™ Advanced Audio Framework (AAF) is a collection of popular audio codecs and post-processing effects, highly tuned to run efficiently on META DSP threads and presented in an easy-to-use framework using component-based stream construction.

The META AAF can run on a single META thread to provide a self-contained subsystem or be partitioned across multiple threads to optimize loading for complex multiple-input, multiple-output systems; the META processor supports up to four processor threads, each individually configurable to run general purpose or DSP code.

Different configurations of the AAF are available containing the appropriate audio codecs and postprocessing functions for application areas such as digital radio, connected audio appliances, mobile TV, digital TV, and home theatre systems.
