Stereo output transputer interface board

There are many applications, particularly within the field of music synthesis and studio post-production, where a stereo output is required. Stereo is the industry standard format for the great majority of commercial recordings which are often subject to digital processing as well as being the format in which most composers and researchers in music technology carry out their work. It is also the audio format used for sound localisation processing and much psychoacoustic testing. This paper presents a design of a high performance stereo output system that can be interfaced to a parallel processing environment. The parallel processing environment and interfaces are based around transputers, the stereo processing is based around a Philips SAA7322/SAA7323 CMOS chip.
