More and more vendors are adding audio, and occasionally telephony, to their workstations. At the same time, with the growing popularity of window systems and mice, workstation applications are becoming more interactive and graphical. Audio provides a new dimension of interaction for the user, and the possibility of a powerful new data type for multi-media applications. This paper describes our architecture for the integration of audio and telephony into a graphics workstation environment. Our framework is a client-server model; at the heart is an audio server that allows shared access to audio hardware, provides synchronization primitives to be used with other media and presents a device-independent abstraction to the application programmer.
