Audio-Pro with Multiple DSPs and Dynamic Load Distribution

The latest professional Karaoke system released in Japan has no ASIC for sound synthesis and effects processing, but instead a small group of load-sharing DSPs that co-operatively handle the varied and dynamically varying tasks of complex high-quality audio performance. The software-only system is a first for the audio industry, heralding a new generation of downloadable and task-sensitive software that delivers time-critical performance from distributed general-purpose silicon. The tasks of emulating a 64-voice orchestra plus real-time MPEG decode, live voice tracking with pitch and tempo following, and a full range of audio effects processing are represented in a network of active objects which are just-in-time serviced by a co-operating array of SIMD DSPs.
