Abstract

The world's first software-only Karaoke Machine released in Japan (2002) has no ASIC for sound synthesis and effects processing, but instead a group of load-sharing DSPs that run a multiprocessor version of the author's Extended Csound to support a 64-voice orchestra, real-time MPEG decode, live voice tracking with pitch and tempo following and a full range of audio effects. A new version of the software aimed at low-cost low-power silicon now enables similar interactive performance on lightweight mobile platforms with the same professional audio quality and Internet connectivity. This presentation will describe the system, and close with a live demonstration.
